                                    short rowLen)

方法详细资料

getRowLength

public short getRowLength()

指定者:

getRowLength 在接口中 Cell

覆盖:

getRowLength 在类中 ByteBufferKeyValue

返回:

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

getKeyLength

public int getKeyLength()

heapSize

public long heapSize()

指定者:

heapSize 在接口中 HeapSize

覆盖:

heapSize 在类中 ByteBufferKeyValue

返回:

Approximate 'exclusive deep size' of implementing object. Includes count of payload and hosting object sizings.

getSerializedSize

public int getSerializedSize()

Override by just returning the length for saving cost of method dispatching. If not, it will call ExtendedCell.getSerializedSize() firstly, then forward to KeyValue.getSerializedSize(boolean). (See HBASE-21657)

指定者:

getSerializedSize 在接口中 Cell

指定者:

getSerializedSize 在接口中 ExtendedCell

覆盖:

getSerializedSize 在类中 ByteBufferKeyValue

返回:

Serialized size (defaults to include tag length).

equals

public boolean equals(Object other)

从类复制的说明: ByteBufferKeyValue

Needed doing 'contains' on List. Only compares the key portion, not the value.

覆盖:

equals 在类中 ByteBufferKeyValue

hashCode

public int hashCode()

从类复制的说明: ByteBufferKeyValue

In line with ByteBufferKeyValue.equals(Object), only uses the key portion, not the value.

覆盖:

hashCode 在类中 ByteBufferKeyValue
