Interface BaseArray

All Superinterfaces:

TypeGetterSetters

All Known Implementing Classes:

BinaryArray, GenericArray

public interface BaseArray
extends TypeGetterSetters

An interface for array used internally in Flink Table/SQL.

There are different implementations depending on the scenario: After serialization, it becomes the BinaryArray format. Convenient updates use the GenericArray format.

Method Detail

numElements

int numElements()

isNullAt

boolean isNullAt(int pos)

Description copied from interface: TypeGetterSetters

Because the specific row implementation such as BinaryRow uses the binary format. We must first determine if it is null, and then make a specific get.

Specified by:

isNullAt in interface TypeGetterSetters

Returns:

true if this field is null.

setNullAt

void setNullAt(int pos)

Description copied from interface: TypeGetterSetters

Set null to this field.

Specified by:

setNullAt in interface TypeGetterSetters

setNotNullAt

void setNotNullAt(int pos)

setNullLong

void setNullLong(int pos)

setNullInt

void setNullInt(int pos)

setNullBoolean
