Method Detail

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.

Specified by:

reserveDictionaryIds in interface WritableColumnVector

Overrides:

reserveDictionaryIds in class AbstractHeapVector

getDictionaryIds

public HeapIntVector getDictionaryIds()

Description copied from class: AbstractHeapVector

Returns the underlying integer column for ids of dictionary.

Specified by:

getDictionaryIds in interface WritableColumnVector

Overrides:

getDictionaryIds in class AbstractHeapVector

getBoolean

public boolean getBoolean(int i)

Specified by:

getBoolean in interface BooleanColumnVector

setBoolean

public void setBoolean(int i,
                       boolean value)

Description copied from interface: WritableBooleanVector

Set boolean at rowId with the provided value.

Specified by:

setBoolean in interface WritableBooleanVector

fill

public void fill(boolean value)

Description copied from interface: WritableBooleanVector

Fill the column vector with the provided value.

Specified by:
