Constructor Detail

FirstOnRowCell

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

Method Detail

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: Cell

Returns the type of cell in a human readable format using Cell.Type. Note : This does not expose the internal types of Cells like KeyValue.Type.Maximum and KeyValue.Type.Minimum

Returns:

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