  • Method Details

    • reset

      void reset()
      Resets the column to default state.

    • setNullAt

      void setNullAt(int rowId)
      Set null at rowId.

    • setNulls

      void setNulls(int rowId, int count)
      Set nulls from rowId to rowId + count (exclude).

    • fillWithNulls

      void fillWithNulls()
      Fill the column vector with nulls.

    • setDictionary

      void setDictionary(Dictionary dictionary)
      Set the dictionary, it should work with dictionary ids.

    • hasDictionary

      boolean hasDictionary()
      Check if there's a dictionary.

    • reserveDictionaryIds

      WritableIntVector reserveDictionaryIds(int capacity)
      Reserve a integer column for ids of dictionary. The size of return WritableIntVector should be equal to or bigger than capacity. DictionaryIds must inconsistent with setDictionary(org.apache.flink.table.data.columnar.vector.Dictionary). We don't support a mix of dictionary.

    • getDictionaryIds

      WritableIntVector getDictionaryIds()
      Get reserved dictionary ids.
