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.

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
