java.lang.Objectorg.apache.hadoop.hbase.filter.RowFilterSet
public class RowFilterSet
Implementation of RowFilterInterface that represents a set of RowFilters which will be evaluated with a specified boolean operator MUST_PASS_ALL (!AND) or MUST_PASS_ONE (!OR). Since you can use RowFilterSets as children of RowFilterSet, you can create a hierarchy of filters to be evaluated.

Method Summary | |
---|---|
void |
addFilter(RowFilterInterface filter)
Add a filter. |
boolean |
filterAllRemaining()
Determines if the filter has decided that all remaining results should be filtered (skipped). |
boolean |
filterColumn(byte[] rowKey,
byte[] colKey,
byte[] data)
Filters on row key, column name, and column value. |
boolean |
filterRow(SortedMap<byte[],Cell> columns)
Filter on the fully assembled row. |
boolean |
filterRowKey(byte[] rowKey)
Filters on just a row key. |
RowFilterSet.Operator |
getOperator()
Get the operator. |
boolean |
processAlways()
Returns whether or not the filter should always be processed in any filtering call. |
void |
readFields(DataInput in)
|
void |
reset()
Resets the state of the filter. |
void |
rowProcessed(boolean filtered,
byte[] rowKey)
Called to let filter know the final decision (to pass or filter) on a given row. |
void |
validate(byte[][] columns)
Validates that this filter applies only to a subset of the given columns. |
