    - #### INSTANCE

          public static final TruePredicate INSTANCE

      An instance of the TruePredicate.

  - ### Constructor Detail

    - #### TruePredicate

          public TruePredicate()

  - ### Method Detail

    - #### truePredicate

          public static <K,V> TruePredicate<K,V> truePredicate()

    - #### writeData

          public void writeData(ObjectDataOutput out)
                         throws IOException

      Description copied from interface: `DataSerializable`
      Writes object fields to output stream
      Specified by:
        `writeData` in interface `DataSerializable`
      Parameters:
        `out` - output
      Throws:
        `IOException` - if an I/O error occurs. In particular, an `IOException` may be thrown if the output stream has been closed.

    - #### readData

          public void readData(ObjectDataInput in)
                        throws IOException

      Description copied from interface: `DataSerializable`
      Reads fields from the input stream
      Specified by:
        `readData` in interface `DataSerializable`
      Parameters:
        `in` - input
      Throws:
        `IOException` - if an I/O error occurs. In particular, an `IOException` may be thrown if the input stream has been closed.

    - #### apply

          public boolean apply(Map.Entry mapEntry)

      Description copied from interface: `Predicate`
      Applies this predicate to the given map entry.

      Implementations must be thread-safe, since this method may be called by multiple threads concurrently.

      Specified by:
        `apply` in interface `Predicate<K,V>`
      Parameters:
        `mapEntry` - the map entry to apply this predicate to.
      Returns:
        `true` if the given map entry matches this predicate, `false` otherwise.

      Specified by:
        `getFactoryId` in interface `IdentifiedDataSerializable`
      Returns:
        factory ID

    - #### getId

          public int getId()

      Description copied from interface: `IdentifiedDataSerializable`
      Returns type identifier for this class. It should be unique per DataSerializableFactory.

      Returns:
        type ID

    - #### equals

          public boolean equals(Object o)
