Method Detail

numElements

public int numElements()

Description copied from interface: BaseMap

Invoke by codeGens.

Specified by:

numElements in interface BaseMap

pointTo

public void pointTo(org.apache.flink.core.memory.MemorySegment[] segments,
                    int offset,
                    int sizeInBytes)

Overrides:

pointTo in class BinarySection

keyArray

public BinaryArray keyArray()

valueArray

public BinaryArray valueArray()

toJavaMap

public Map<Object,Object> toJavaMap(org.apache.flink.table.types.logical.LogicalType keyType,
                                    org.apache.flink.table.types.logical.LogicalType valueType)

Description copied from interface: BaseMap

This method will return a Java map containing INTERNAL type data. If you want a Java map containing external type data, you have to use converters.

Specified by:

toJavaMap in interface BaseMap

copy

public BinaryMap copy()

copy

public BinaryMap copy(BinaryMap reuse)

hashCode

public int hashCode()

Overrides:

hashCode in class BinarySection

valueOf

public static BinaryMap valueOf(BinaryArray key,
                                BinaryArray value)

readBinaryMapFieldFromSegments

public static BinaryMap readBinaryMapFieldFromSegments(org.apache.flink.core.memory.MemorySegment[] segments,
                                                       int baseOffset,
                                                       long offsetAndSize)
