  • Method Details

    • reset

      public void reset()
      Resets the column to default state. - fills the isNull array with false. - sets noNulls to true.

    • setNullAt

      public void setNullAt(int i)
      Description copied from interface: WritableColumnVector
      Set null at rowId.

    • setNulls

      public void setNulls(int i, int count)
      Description copied from interface: WritableColumnVector
      Set nulls from rowId to rowId + count (exclude).

    • fillWithNulls

      public void fillWithNulls()
      Description copied from interface: WritableColumnVector
      Fill the column vector with nulls.

    • isNullAt

      public boolean isNullAt(int i)

    • reserveDictionaryIds

      public HeapIntVector reserveDictionaryIds(int capacity)
      Description copied from interface: WritableColumnVector
      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 WritableColumnVector.setDictionary(org.apache.flink.table.data.columnar.vector.Dictionary). We don't support a mix of dictionary.

    • getDictionaryIds

      public HeapIntVector getDictionaryIds()
      Returns the underlying integer column for ids of dictionary.

    • getLen

      public int getLen()
