Examples of org.apache.hadoop.hbase.filter.ValueFilter

org.apache.hadoop.hbase.filter.ValueFilter
This filter is used to filter based on column value. It takes an operator (equal, greater, not equal, etc) and a byte [] comparator for the cell value.
This filter can be wrapped with {@link WhileMatchFilter} and {@link SkipFilter}to add more control.
Multiple filters can be combined using {@link FilterList}.
To test the value of a single qualifier when scanning multiple qualifiers, use {@link SingleColumnValueFilter}.
