org.apache.hadoop.hbase.filter.WhileMatchFilter
public class WhileMatchFilter
A wrapper filter that returns true from filterAllRemaining()
as soon
as the wrapped filters Filter.filterRowKey(byte[], int, int)
,
Filter.filterKeyValue(org.apache.hadoop.hbase.KeyValue)
,
Filter.filterRow()
or
Filter.filterAllRemaining()
methods
returns true.

boolean |
filterAllRemaining()
Filters that never filter all remaining can inherit this implementation that never stops the filter early. |
Filter.ReturnCode |
filterKeyValue(KeyValue v)
Filters that dont filter by key value can inherit this implementation that includes all KeyValues. |
boolean |
filterRow()
Filters that never filter by rows based on previously gathered state from FilterBase.filterKeyValue(KeyValue) 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. |

Filters that are purely stateless and do nothing in their reset() methods can inherit this null/empty implementation. |
