FirstOnRowCell(byte[] row, int roffset, short rlength)

Method Summary

Modifier and Type	Method	Description
byte[]	getRowArray()	Contiguous raw bytes that may start at any index in the containing array.
short	getRowLength()	Returns Number of row bytes.
int	getRowOffset()	Returns Array index of first row byte
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

FirstOnRowCell

public FirstOnRowCell(byte[] 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.

getRowArray

public byte[] getRowArray()

Description copied from interface: Cell

Contiguous raw bytes that may start at any index in the containing array. Max length is Short.MAX_VALUE which is 32,767 bytes.

Specified by:

getRowArray in interface Cell

Overrides:

getRowArray in class PrivateCellUtil.EmptyCell

Returns:

The array containing the row bytes.

getRowOffset

public int getRowOffset()

Description copied from interface: Cell

Returns Array index of first row byte

Specified by:

getRowOffset in interface Cell

Overrides:

getRowOffset in class PrivateCellUtil.EmptyCell

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.EmptyCell

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
