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

org.apache.hadoop.hbase.filter.WhileMatchFilter
A wrapper filter that returns true from {@link #filterAllRemaining()} as soonas the wrapped filters {@link Filter#filterRowKey(byte[],int,int)}, {@link Filter#filterKeyValue(org.apache.hadoop.hbase.KeyValue)}, {@link org.apache.hadoop.hbase.filter.Filter#filterRow()} or{@link org.apache.hadoop.hbase.filter.Filter#filterAllRemaining()} methodsreturns true.
