org.apache.hadoop.hbase.rest.filter.FilterFactory

Constructs Filters from JSON. Filters are defined as JSON Objects of the form: { "type" : "FILTER_CLASS_NAME", "args" : "FILTER_ARGUMENTS" } For Filters like WhileMatchRowFilter, nested Filters are supported. Just serialize a different filter in the form (for instance if you wanted to use WhileMatchRowFilter with a StopRowFilter: { "type" : "WhileMatchRowFilter", "args" : { "type" : "StopRowFilter", "args" : "ROW_KEY_TO_STOP_ON" } } For filters like RowSetFilter, nested Filters AND Filter arrays are supported. So for instance If one wanted to do a RegExp RowFilter UNIONed with a WhileMatchRowFilter(StopRowFilter), you would look like this: { "type" : "RowFilterSet", "args" : [ { "type" : "RegExpRowFilter", "args" : "MY_REGULAR_EXPRESSION" }, { "type" : "WhileMatchRowFilter" "args" : { "type" : "StopRowFilter" "args" : "MY_STOP_ROW_EXPRESSION" } } ] }

   * @return RowSetFilter with all input filters in an AND Statement
   * @throws org.apache.hadoop.hbase.rest.exception.HBaseRestException
   */
  protected RowFilterInterface unionFilters(String filters)

    FilterFactory f = RESTConstants.filterFactories.get("RowFilterSet");
    return f.getFilterFromJSON(filters);
