Enum StateMetaInfoSnapshotReadersWriters.StateTypeHint

java.lang.Object

java.lang.Enum<StateMetaInfoSnapshotReadersWriters.StateTypeHint>

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

All Implemented Interfaces:

Serializable, Comparable<StateMetaInfoSnapshotReadersWriters.StateTypeHint>

Enclosing class:

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.

Method Detail

values

public static StateMetaInfoSnapshotReadersWriters.StateTypeHint[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (StateMetaInfoSnapshotReadersWriters.StateTypeHint c : StateMetaInfoSnapshotReadersWriters.StateTypeHint.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static StateMetaInfoSnapshotReadersWriters.StateTypeHint valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
