Modifier and Type | Method and Description |

static Filter |
createFilterFromArguments(ArrayList<byte[]> filterArguments) |
boolean |
filterAllRemaining()
Filters that never filter all remaining can inherit this implementation that
never stops the filter early.
|
Filter.ReturnCode |
filterKeyValue(Cell v)
Filters that dont filter by key value can inherit this implementation that
includes all Cells.
|
boolean |
filterRow()
Filters that never filter by rows based on previously gathered state from
FilterBase.filterKeyValue(Cell) can inherit this implementation that
never filters a row. |
boolean |
filterRowKey(byte[] buffer,
int offset,
int length)
Filters that do not filter by row key can inherit this implementation that
never filters anything.

static PrefixFilter |
parseFrom(byte[] pbBytes) |
void |
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.
