Constructor Detail

RecordOnHeap

public RecordOnHeap(long seq,
                    int size,
                    boolean isTombstone,
                    int additionalInt)

Method Detail

rawSeqValue

public final long rawSeqValue()

Specified by:

rawSeqValue in class Record

Returns:

the value of the raw, low-level "seq" property which encodes both the record's sequence number and whether it's alive. If zero, then this object does not relate to any live record, but garbageCount keeps tracking the number of garbage records on the same key in the same chunk.

rawSizeValue

public final int rawSizeValue()

Specified by:

rawSizeValue in class Record

Returns:

the raw, low-level "size" property which encodes both the size of the record and whether it's a tombstone.

keyPrefix

public long keyPrefix(KeyHandle kh)

Specified by:

keyPrefix in class Record

Parameters:

kh - the key handle associated with this record

Returns:

the key prefix associated with this record

negateSeq

public final void negateSeq()

Description copied from class: Record

Negates the value of the rawSeq property.

Specified by:

negateSeq in class Record

additionalInt

public final int additionalInt()

Specified by:

additionalInt in class Record

Returns:

the "additional int" property which, for a value record, denotes the garbage count and for a tombstone denotes file position.

decrementGarbageCount

public final int decrementGarbageCount()

Description copied from class: Record

Decrements this record's garbage count.

Specified by:

decrementGarbageCount in class Record

incrementGarbageCount

public final void incrementGarbageCount()

Description copied from class: Record

Increments this record's garbage count.

Specified by:

incrementGarbageCount in class Record

setAdditionalInt

public final void setAdditionalInt(int newCount)

Description copied from class: Record

Sets the raw "additional int" property on this record.

Specified by:

setAdditionalInt in class Record

See Also:

Record.additionalInt()

setRawSeqSize

public final void setRawSeqSize(long rawSeqValue,
                                int rawSizeValue)

Description copied from class: Record

Sets the raw "seq" and "size" values on this record.

Specified by:

setRawSeqSize in class Record

See Also:

Record.rawSeqValue(), Record.rawSizeValue()
