filterAllRemaining()
Filters that never filter all remaining can inherit this implementation that
never stops the filter early.
|
Filter.ReturnCode |
filterKeyValue(Cell v)
A way to filter based on the column family, column qualifier and/or the column value.

boolean |
filterRowKey(Cell cell)
Filters a row based on the row key.

reset()
Filters that are purely stateless and do nothing in their reset() methods can inherit
this null/empty implementation.
|
byte[] |
toByteArray()
Return length 0 byte array for Filters that don't require special serialization
|
String |
toString()
Return filter's info for debugging and logging purpose.
