java.lang.Object

org.apache.flink.table.dataformat.GenericMap

所有已实现的接口:

BaseMap

public class GenericMap
extends Object
implements BaseMap

A GenericMap is a map where all the keys have the same type, and all the values have the same type. It can be considered as a wrapper class of the normal java map.

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

toJavaMap

public Map 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

get

public Object get(Object key)

toString

public String toString()

覆盖:

toString 在类中 Object

getMap
