org.apache.hadoop.hbase.filter.Filter.filterRowKey()
Filters a row based on the row key. If this returns true, the entire row will be excluded. If false, each KeyValue in the row will be passed to {@link #filterKeyValue(KeyValue)} below. @param buffer buffer containing row key @param offset offset into buffer where row key starts @param length length of the row key @return true, remove entire row, false, include the row (maybe).

    Filter deserializedFilter = FilterList.parseFrom(serializedFilter);


    // Filter an entity with the deserialized filter.
    EntityId entityId = factory.getEntityId(10, 10L);
    byte[] hbaseKey = entityId.getHBaseRowKey();
    boolean filtered = deserializedFilter.filterRowKey(hbaseKey, 0, hbaseKey.length);
    assertEquals(INCLUDE, filtered);
