Method Summary

Modifier and Type	Method	Description
ByteBuffer	getRowByteBuffer()	Returns The ByteBuffer containing the row bytes.
short	getRowLength()	Returns Number of row bytes.
int	getRowPosition()	Returns Position in the ByteBuffer where row bytes start
long	getTimestamp()	Return a long value representing time at which this cell was "Put" into the row.
Cell.Type	getType()	Typically, at server side, you'd better always use the ExtendedCell.getTypeByte() as this method does not expose the Maximum and Minimum because they will not be returned to client, but at server side, we do have cells with these types so if you use this method it will cause exceptions.
byte	getTypeByte()	Returns The byte representation of the KeyValue.TYPE of this cell: one of Put, Delete, etc
long	heapSize()	Return the approximate 'exclusive deep size' of implementing object.

Constructor Details

LastOnRowByteBufferExtendedCell

public LastOnRowByteBufferExtendedCell(ByteBuffer row,
 int roffset,
 short rlength)

Method Details

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.

getRowByteBuffer

public ByteBuffer getRowByteBuffer()

Description copied from class: ByteBufferExtendedCell

Returns The ByteBuffer containing the row bytes.

Overrides:

getRowByteBuffer in class PrivateCellUtil.EmptyByteBufferExtendedCell

getRowPosition

public int getRowPosition()

Description copied from class: ByteBufferExtendedCell

Returns Position in the ByteBuffer where row bytes start

Overrides:

getRowPosition in class PrivateCellUtil.EmptyByteBufferExtendedCell

getRowLength

public short getRowLength()

Description copied from interface: Cell

Returns Number of row bytes. Must be < rowArray.length - offset.

Specified by:

getRowLength in interface Cell

Overrides:

getRowLength in class PrivateCellUtil.EmptyByteBufferExtendedCell

getTimestamp

public long getTimestamp()

Description copied from interface: Cell

Return a long value representing time at which this cell was "Put" into the row. Typically represents the time of insertion, but can be any value from 0 to Long.MAX_VALUE.

getTypeByte

public byte getTypeByte()

Description copied from interface: ExtendedCell

Returns The byte representation of the KeyValue.TYPE of this cell: one of Put, Delete, etc

getType

public Cell.Type getType()

Description copied from interface: ExtendedCell

Typically, at server side, you'd better always use the ExtendedCell.getTypeByte() as this method does not expose the Maximum and Minimum because they will not be returned to client, but at server side, we do have cells with these types so if you use this method it will cause exceptions.

Returns:

The data type this cell: one of Put, Delete, etc
