枚举 StateMetaInfoSnapshotReadersWriters.StateTypeHint

java.lang.Object

java.lang.Enum<StateMetaInfoSnapshotReadersWriters.StateTypeHint>

org.apache.flink.runtime.state.metainfo.StateMetaInfoSnapshotReadersWriters.StateTypeHint

所有已实现的接口:

Serializable, Comparable<StateMetaInfoSnapshotReadersWriters.StateTypeHint>

封闭类:

StateMetaInfoSnapshotReadersWriters

public static enum StateMetaInfoSnapshotReadersWriters.StateTypeHint
extends Enum<StateMetaInfoSnapshotReadersWriters.StateTypeHint>

Enum for backwards compatibility. This gives a hint about the expected state type for which a StateMetaInfoSnapshot should be deserialized.

TODO this can go away after we eventually drop backwards compatibility with all versions < 5.

valueOf

public static StateMetaInfoSnapshotReadersWriters.StateTypeHint valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
