Overrides:

getValueArray in class PrivateCellUtil.TagRewriteByteBufferExtendedCell

Returns:

The array containing the value bytes.

getValueOffset

public int getValueOffset()

Description copied from interface: Cell

Returns Array index of first value byte

Specified by:

getValueOffset in interface Cell

Overrides:

getValueOffset in class PrivateCellUtil.TagRewriteByteBufferExtendedCell

getValueLength

public int getValueLength()

Description copied from interface: Cell

Returns Number of value bytes. Must be < valueArray.length - offset.

Specified by:

getValueLength in interface Cell

Overrides:

getValueLength in class PrivateCellUtil.TagRewriteByteBufferExtendedCell

getValueByteBuffer

public ByteBuffer getValueByteBuffer()

Description copied from class: ByteBufferExtendedCell

Returns Position in the ByteBuffer where value bytes start

Overrides:

getValuePosition in class PrivateCellUtil.TagRewriteByteBufferExtendedCell

heapSize

public long heapSize()

Description copied from interface: HeapSize

Return the approximate 'exclusive deep size' of implementing object. Includes count of payload and hosting object sizings.

Specified by:

heapSize in interface HeapSize

Overrides:

heapSize in class PrivateCellUtil.TagRewriteByteBufferExtendedCell

write

public int write(OutputStream out,
 boolean withTags)
          throws IOException

Description copied from interface: ExtendedCell
