getRowArray
Implement Cell interface- Specified by:
getRowArray
in interfaceCell
- Returns:
- The array containing the row bytes.
-
getRowOffset
Description copied from interface:Cell
Returns Array index of first row byte- Specified by:
getRowOffset
in interfaceCell
-
getRowLength
Description copied from interface:Cell
Returns Number of row bytes. Must be < rowArray.length - offset.- Specified by:
getRowLength
in interfaceCell
-
getFamilyArray
Description copied from interface:Cell
Contiguous bytes composed of legal HDFS filename characters which may start at any index in the containing array. Max length is Byte.MAX_VALUE, which is 127 bytes.- Specified by:
getFamilyArray
in interfaceCell
- Returns:
- the array containing the family bytes.
-
getFamilyOffset
Description copied from interface:Cell
Returns Array index of first family byte- Specified by:
getFamilyOffset
in interfaceCell
-
getFamilyLength
Description copied from interface:Cell
Returns Number of family bytes. Must be < familyArray.length - offset.- Specified by:
getFamilyLength
in interfaceCell
-
getQualifierArray
Description copied from interface:Cell
Contiguous raw bytes that may start at any index in the containing array.- Specified by:
getQualifierArray
in interfaceCell
- Returns:
- The array containing the qualifier bytes.
-
getQualifierOffset
Description copied from interface:Cell
Returns Array index of first qualifier byte- Specified by:
getQualifierOffset
in interfaceCell
-
getQualifierLength
Description copied from interface:Cell
Returns Number of qualifier bytes. Must be < qualifierArray.length - offset.- Specified by:
getQualifierLength
in interfaceCell
-
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.- Specified by:
getTimestamp
in interfaceCell
-
getTypeByte
Description copied from interface:ExtendedCell
Returns The byte representation of the KeyValue.TYPE of this cell: one of Put, Delete, etc- Specified by:
getTypeByte
in interfaceExtendedCell
-
getSequenceId
Description copied from interface:ExtendedCell
A region-specific unique monotonically increasing sequence ID given to each Cell. It always exists for cells in the memstore but is not retained forever. It will be kept forHConstants.KEEP_SEQID_PERIOD
days, but generally becomes irrelevant after the cell's row is no longer involved in any operations that require strict consistency.- Specified by:
getSequenceId
in interfaceExtendedCell
- Returns:
- seqId (always > 0 if exists), or 0 if it no longer exists
-
getValueArray
Description copied from interface:Cell
Contiguous raw bytes that may start at any index in the containing array. Max length is Integer.MAX_VALUE which is 2,147,483,647 bytes.- Specified by:
getValueArray
in interfaceCell
- Returns:
- The array containing the value bytes.
-
getValueOffset
Description copied from interface:Cell
Returns Array index of first value byte- Specified by:
getValueOffset
in interfaceCell
-
getValueLength
Description copied from interface:Cell
Returns Number of value bytes. Must be < valueArray.length - offset.- Specified by:
getValueLength
in interfaceCell
-
getTagsArray
Description copied from interface:RawCell
Contiguous raw bytes representing tags that may start at any index in the containing array.- Specified by:
getTagsArray
in interfaceRawCell
- Returns:
- the tags byte array
-
getTagsOffset
Description copied from interface:RawCell
Return the first offset where the tags start in the Cell- Specified by:
getTagsOffset
in interfaceRawCell
-
getTagsLength
Description copied from interface:RawCell
HBase internally uses 2 bytes to store tags length in Cell. As the tags length is always a non-negative number, to make good use of the sign bit, the max of tags length is defined 2 * Short.MAX_VALUE + 1 = 65535. As a result, the return type is int, because a short is not capable of handling that. Please note that even if the return type is int, the max tags length is far less than Integer.MAX_VALUE.- Specified by:
getTagsLength
in interfaceRawCell
- Returns:
- the total length of the tags in the Cell.
-
heapSize
Implement HeapSize interface -
clone
Implement Cloneable interface- Overrides:
clone
in classObject
- Throws:
CloneNotSupportedException
-
