|---|---|
void |

boolean |
equals(Object other)
Needed doing 'contains' on List.
|
byte[] |
getFamilyArray()
Contiguous bytes composed of legal HDFS filename characters which may start at any index in the
containing array.

getKey()
Do not use unless you have to.
|
int |
getKeyLength() |
int |
getKeyOffset() |
byte[] |
getQualifierArray()
Contiguous raw bytes that may start at any index in the containing array.
|
int |
getQualifierLength() |
private int |
getQualifierLength(int rlength,
int flength) |
int |
getQualifierOffset() |
byte[] |
getRowArray()
Contiguous raw bytes that may start at any index in the containing array.
|
short |
getRowLength() |
int |
getRowOffset() |
byte[] |
getTagsArray()
Contiguous raw bytes representing tags that may start at any index in the containing array.
|
int |
getTagsLength()
This returns the total length of the tag bytes
|
int |
getTagsOffset()
This returns the offset where the tag actually starts.
|
long |
getTimestamp() |
int |
getTimestampOffset() |
byte |
getTypeByte() |
byte[] |
getValueArray()
Contiguous raw bytes that may start at any index in the containing array.
|
int |
getValueLength() |
int |
getValueOffset() |
int |
hashCode()
In line with
KeyValue.equals(Object), only uses the key portion, not the value. |
long |
heapSize()
HeapSize implementation
We do not count the bytes in the rowCache because it should be empty for a KeyValue in the
MemStore.
|
void |
set(KeyValue.KeyOnlyKeyValue keyOnlyKeyValue) |
void |
setKey(byte[] key,
int offset,
int length)
A setter that helps to avoid object creation every time and whenever
there is a need to create new KeyOnlyKeyValue.
|
String |
toString() |
int |
write(OutputStream out,
boolean withTags)
Write this cell to an OutputStream in a
KeyValue format. |
