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.

filterAllRemaining()
Filters that never filter all remaining can inherit this implementation that never stops the filter early. |

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 |
boolean |
filterRowKey(byte[] buffer,
int offset,
int length)
Filters that do not filter by row key can inherit this implementation that never filters anything. |
