类 BinaryMap

java.lang.Object

org.apache.flink.table.dataformat.BinarySection

org.apache.flink.table.dataformat.BinaryMap

所有已实现的接口:

BaseMap, BinaryFormat

public final class BinaryMap
extends BinarySection
implements BaseMap

[4 byte(keyArray size in bytes)] + [Key BinaryArray] + [Value BinaryArray].

BinaryMap are influenced by Apache Spark UnsafeMapData.

构造器详细资料

BinaryMap

public BinaryMap()

方法详细资料

numElements

public int numElements()

从接口复制的说明: BaseMap

Invoke by codeGens.

指定者:

numElements 在接口中 BaseMap

pointTo

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

覆盖:

pointTo 在类中 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)

从接口复制的说明: 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.

指定者:

toJavaMap 在接口中 BaseMap

copy

public BinaryMap copy()

copy

public BinaryMap copy(BinaryMap reuse)

hashCode

public int hashCode()

覆盖:

hashCode 在类中 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)
