Method Detail

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.paimon.data.columnar.Dictionary). We don't support a mix of dictionary.

getDictionaryIds

WritableIntVector getDictionaryIds()

Get reserved dictionary ids.

setAllNull

void setAllNull()

Set all values to null.

isAllNull

boolean isAllNull()

Check if all values are null.

reserve

void reserve(int capacity)

getElementsAppended

int getElementsAppended()

addElementsAppended

void addElementsAppended(int num)

reserveAdditional

default void reserveAdditional(int additionalCapacity)
