    All Methods Static Methods Instance Methods Abstract Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `protected String` | `_addName(int[] quads, int qlen, int lastQuadBytes)` This is the main workhorse method used when we take a symbol table miss.
    `protected JsonToken` | `_closeArrayScope()`
    `protected void` | `_closeInput()`
    `protected JsonToken` | `_closeObjectScope()`
    `protected JsonToken` | `_eofAsNextToken()` Helper method called at point when all input has been exhausted and input feeder has indicated no more input will be forthcoming.
    `protected JsonToken` | `_fieldComplete(String name)`
    `protected String` | `_findName(int q1, int lastQuadBytes)`
    `protected String` | `_findName(int q1, int q2, int lastQuadBytes)`

    `protected void` | `_reportInvalidChar(int c)`
    `protected void` | `_reportInvalidInitial(int mask)`
    `protected void` | `_reportInvalidOther(int mask)`
    `protected void` | `_reportInvalidOther(int mask, int ptr)`

    `protected JsonToken` | `_startObjectScope()`
    `protected void` | `_updateTokenLocation()`
    `protected JsonToken` | `_valueComplete(JsonToken t)`
    `protected JsonToken` | `_valueCompleteInt(int value, String asText)`
    `protected JsonToken` | `_valueNonStdNumberComplete(int type)`
    `boolean` | `canParseAsync()` Method that can be called to determine if this parser instance uses non-blocking ("asynchronous") input access for decoding or not.
    `byte[]` | `getBinaryValue(Base64Variant b64variant)` Method that can be used to read (and consume -- results may not be accessible using other methods after the call) base64-encoded binary data included in the current textual JSON value.
    `ObjectCodec` | `getCodec()` Accessor for `ObjectCodec` associated with this parser, if any.
    `JsonLocation` | `getCurrentLocation()` Method that returns location of the last processed character; usually for error reporting purposes
    `Object` | `getEmbeddedObject()` Accessor that can be called if (and only if) the current token is `JsonToken.VALUE_EMBEDDED_OBJECT`.
    `Object` | `getInputSource()` Method that can be used to get access to object that is used to access input being parsed; this is usually either `InputStream` or `Reader`, depending on what parser was constructed with.
    `String` | `getText()` Method for accessing textual representation of the current event; if no current event (before first call to `ParserMinimalBase.nextToken()`, or after encountering end-of-input), returns null.
    `int` | `getText(Writer writer)` Method to read the textual representation of the current token in chunks and pass it to the given Writer.
    `char[]` | `getTextCharacters()` Method similar to `JsonParser.getText()`, but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information.
    `int` | `getTextLength()` Accessor used with `JsonParser.getTextCharacters()`, to know length of String stored in returned buffer.
    `int` | `getTextOffset()` Accessor used with `JsonParser.getTextCharacters()`, to know offset of the first text content character within buffer.
    `JsonLocation` | `getTokenLocation()` Method that return the starting location of the current token; that is, position of the first character from input that starts the current token.
    `String` | `getValueAsString()` Method that will try to convert value of current token to a `String`.
    `String` | `getValueAsString(String defValue)` Method that will try to convert value of current token to a `String`.
    `boolean` | `hasTextCharacters()` Method that can be used to determine whether calling of `JsonParser.getTextCharacters()` would be the most efficient way to access textual content for the event parser currently points to.
    `int` | `readBinaryValue(Base64Variant b64variant, OutputStream out)` Similar to `JsonParser.readBinaryValue(OutputStream)` but allows explicitly specifying base64 variant to use.
    `abstract int` | `releaseBuffered(OutputStream out)` Method that can be called to push back any content that has been read but not consumed by the parser.
    `void` | `setCodec(ObjectCodec c)` Setter that allows defining `ObjectCodec` associated with this parser, if any.
    `protected ByteQuadsCanonicalizer` | `symbolTableForTests()`

      When tokenizing non-standard ("odd") tokens, this is the type to consider; also works as index to actual textual representation.

    - #### _currBufferStart

          protected int _currBufferStart

      Since we are fed content that may or may not start at zero offset, we need to keep track of the first byte within that buffer, to be able to calculate logical offset within input "stream"

    - #### _currInputRowAlt

          protected int _currInputRowAlt

      Alternate row tracker, used to keep track of position by `\r` marker (whereas `_currInputRow` tracks `\n`). Used to simplify tracking of linefeeds, assuming that input typically uses various linefeed combinations (`\r`, `\n` or `\r\n`) consistently, in which case we can simply choose max of two row candidates.

    - #### NonBlockingJsonParserBase

          public NonBlockingJsonParserBase(IOContext ctxt,
                                           int parserFeatures,
                                           ByteQuadsCanonicalizer sym)

  - ### Method Detail

    - #### getCodec

          public ObjectCodec getCodec()

      Description copied from class: `JsonParser`
      Accessor for `ObjectCodec` associated with this parser, if any. Codec is used by `JsonParser.readValueAs(Class)` method (and its variants).
      Specified by:
        `getCodec` in class `JsonParser`

    - #### setCodec

          public void setCodec(ObjectCodec c)

      Description copied from class: `JsonParser`
      Setter that allows defining `ObjectCodec` associated with this parser, if any. Codec is used by `JsonParser.readValueAs(Class)` method (and its variants).
      Specified by:
        `setCodec` in class `JsonParser`

    - #### canParseAsync

          public boolean canParseAsync()

      Description copied from class: `JsonParser`
      Method that can be called to determine if this parser instance uses non-blocking ("asynchronous") input access for decoding or not. Access mode is determined by earlier calls via `JsonFactory`; it may not be changed after construction.

      If non-blocking decoding is u (@code true}, it is possible to call `JsonParser.getNonBlockingInputFeeder()` to obtain object to use for feeding input; otherwise (`false` returned) input is read by blocking

      Overrides:
        `canParseAsync` in class `JsonParser`
      Since:
        2.9

    - #### symbolTableForTests

          protected ByteQuadsCanonicalizer symbolTableForTests()

    - #### releaseBuffered

          public abstract int releaseBuffered(OutputStream out)
                                       throws IOException

      Description copied from class: `JsonParser`
      Method that can be called to push back any content that has been read but not consumed by the parser. This is usually done after reading all content of interest using parser. Content is released by writing it to given stream if possible; if underlying input is byte-based it can released, if not (char-based) it can not.
      Overrides:
        `releaseBuffered` in class `JsonParser`
      Returns:
        -1 if the underlying content source is not byte based (that is, input can not be sent to `OutputStream`; otherwise number of bytes released (0 if there was nothing to release)
      Throws:
        `IOException` - if write to stream threw exception

    - #### _releaseBuffers

          protected void _releaseBuffers()
                                  throws IOException

      Description copied from class: `ParserBase`
      Method called to release internal buffers owned by the base reader. This may be called along with `ParserBase._closeInput()` (for example, when explicitly closing this reader instance), or separately (if need be).
      Overrides:
        `_releaseBuffers` in class `ParserBase`
      Throws:
        `IOException`

    - #### getInputSource

          public Object getInputSource()

      Description copied from class: `JsonParser`
      Method that can be used to get access to object that is used to access input being parsed; this is usually either `InputStream` or `Reader`, depending on what parser was constructed with. Note that returned value may be null in some cases; including case where parser implementation does not want to exposed raw source to caller. In cases where input has been decorated, object returned here is the decorated version; this allows some level of interaction between users of parser and decorator object.

      In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.

      Overrides:
        `getInputSource` in class `JsonParser`

    - #### _closeInput

          protected void _closeInput()
                              throws IOException

      Specified by:
        `_closeInput` in class `ParserBase`
      Throws:
        `IOException`

    - #### hasTextCharacters

          public boolean hasTextCharacters()

      Description copied from class: `JsonParser`
      Method that can be used to determine whether calling of `JsonParser.getTextCharacters()` would be the most efficient way to access textual content for the event parser currently points to.

      Default implementation simply returns false since only actual implementation class has knowledge of its internal buffering state. Implementations are strongly encouraged to properly override this method, to allow efficient copying of content by other code.

      Overrides:
        `hasTextCharacters` in class `ParserBase`
      Returns:
        True if parser currently has character array that can be efficiently returned via `JsonParser.getTextCharacters()`; false means that it may or may not exist

    - #### getCurrentLocation

          public JsonLocation getCurrentLocation()

      Description copied from class: `ParserBase`
      Method that returns location of the last processed character; usually for error reporting purposes
      Overrides:
        `getCurrentLocation` in class `ParserBase`

    - #### getTokenLocation

          public JsonLocation getTokenLocation()

      Description copied from class: `ParserBase`
      Method that return the starting location of the current token; that is, position of the first character from input that starts the current token.
      Overrides:
        `getTokenLocation` in class `ParserBase`

    - #### getText

          public String getText()
                         throws IOException

      Method for accessing textual representation of the current event; if no current event (before first call to `ParserMinimalBase.nextToken()`, or after encountering end-of-input), returns null. Method can be called for any event.
      Specified by:
        `getText` in class `ParserMinimalBase`
      Throws:
        `IOException`

    - #### _getText2

          protected final String _getText2(JsonToken t)

    - #### getText

          public int getText(Writer writer)
                      throws IOException

      Description copied from class: `JsonParser`
      Method to read the textual representation of the current token in chunks and pass it to the given Writer. Conceptually same as calling:

            writer.write(parser.getText());

      but should typically be more efficient as longer content does need to be combined into a single `String` to return, and write can occur directly from intermediate buffers Jackson uses.
      Overrides:
        `getText` in class `JsonParser`
      Returns:
        The number of characters written to the Writer
      Throws:
        `IOException`

    - #### getValueAsString

          public String getValueAsString()
                                  throws IOException

      Description copied from class: `JsonParser`
      Method that will try to convert value of current token to a `String`. JSON Strings map naturally; scalar values get converted to their textual representation. If representation can not be converted to a String value (including structured types like Objects and Arrays and null token), default value of null will be returned; no exceptions are thrown.
      Overrides:
        `getValueAsString` in class `ParserMinimalBase`
      Throws:
        `IOException`

    - #### getValueAsString

          public String getValueAsString(String defValue)
                                  throws IOException

      Description copied from class: `JsonParser`
      Method that will try to convert value of current token to a `String`. JSON Strings map naturally; scalar values get converted to their textual representation. If representation can not be converted to a String value (including structured types like Objects and Arrays and null token), specified default value will be returned; no exceptions are thrown.
      Overrides:
        `getValueAsString` in class `ParserMinimalBase`
      Throws:
        `IOException`

    - #### getTextCharacters

          public char[] getTextCharacters()
                                   throws IOException

      Description copied from class: `JsonParser`
      Method similar to `JsonParser.getText()`, but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information. Note, however, that:
      - Textual contents are not guaranteed to start at index 0 (rather, call `JsonParser.getTextOffset()`) to know the actual offset
      - Length of textual contents may be less than the length of returned buffer: call `JsonParser.getTextLength()` for actual length of returned content.

      Note that caller MUST NOT modify the returned character array in any way -- doing so may corrupt current parser state and render parser instance useless.

      The only reason to call this method (over `JsonParser.getText()`) is to avoid construction of a String object (which will make a copy of contents).

      Specified by:
        `getTextCharacters` in class `ParserMinimalBase`
      Throws:
        `IOException`

    - #### getTextLength

          public int getTextLength()
                            throws IOException

      Description copied from class: `JsonParser`
      Accessor used with `JsonParser.getTextCharacters()`, to know length of String stored in returned buffer.
      Specified by:
        `getTextLength` in class `ParserMinimalBase`
      Returns:
        Number of characters within buffer returned by `JsonParser.getTextCharacters()` that are part of textual content of the current token.
      Throws:
        `IOException`

    - #### getTextOffset

          public int getTextOffset()
                            throws IOException

      Description copied from class: `JsonParser`
      Accessor used with `JsonParser.getTextCharacters()`, to know offset of the first text content character within buffer.
      Specified by:
        `getTextOffset` in class `ParserMinimalBase`
      Returns:
        Offset of the first character within buffer returned by `JsonParser.getTextCharacters()` that is part of textual content of the current token.
      Throws:
        `IOException`

    - #### getBinaryValue

          public byte[] getBinaryValue(Base64Variant b64variant)
                                throws IOException

      Description copied from class: `JsonParser`
      Method that can be used to read (and consume -- results may not be accessible using other methods after the call) base64-encoded binary data included in the current textual JSON value. It works similar to getting String value via `JsonParser.getText()` and decoding result (except for decoding part), but should be significantly more performant.

      Note that non-decoded textual contents of the current token are not guaranteed to be accessible after this method is called. Current implementation, for example, clears up textual content during decoding. Decoded binary content, however, will be retained until parser is advanced to the next event.

      Overrides:
        `getBinaryValue` in class `ParserBase`
      Parameters:
        `b64variant` - Expected variant of base64 encoded content (see `Base64Variants` for definitions of "standard" variants).
      Returns:
        Decoded binary data
      Throws:
        `IOException`

    - #### readBinaryValue

          public int readBinaryValue(Base64Variant b64variant,
                                     OutputStream out)
                              throws IOException

      Description copied from class: `JsonParser`
      Similar to `JsonParser.readBinaryValue(OutputStream)` but allows explicitly specifying base64 variant to use.
      Overrides:
        `readBinaryValue` in class `JsonParser`
      Parameters:
        `b64variant` - base64 variant to use
        `out` - Output stream to use for passing decoded binary data
      Returns:
        Number of bytes that were decoded and written via `OutputStream`
      Throws:
        `IOException`

    - #### getEmbeddedObject

          public Object getEmbeddedObject()
                                   throws IOException

      Description copied from class: `JsonParser`
      Accessor that can be called if (and only if) the current token is `JsonToken.VALUE_EMBEDDED_OBJECT`. For other token types, null is returned.

      Note: only some specialized parser implementations support embedding of objects (usually ones that are facades on top of non-streaming sources, such as object trees). One exception is access to binary content (whether via base64 encoding or not) which typically is accessible using this method, as well as `JsonParser.getBinaryValue()`.

      Overrides:
        `getEmbeddedObject` in class `JsonParser`
      Throws:
        `IOException`

                                   throws JsonParseException

      This is the main workhorse method used when we take a symbol table miss. It needs to demultiplex individual bytes, decode multi-byte chars (if any), and then construct Name instance and add it to the symbol table.
      Throws:
        `JsonParseException`
