Method Details

getPersistentStateHolder

@Deprecated
default <K extends Serializable,
V extends Serializable>
StateHolder<K,V> getPersistentStateHolder(String name,
 Class<K> keyClass,
 Class<V> valueClass)

Deprecated.

Replaced by getPersistentStateHolder(String, Class, Class, Predicate, ClassLoader) that takes in a Predicate that authorizes a class for deserialization

Gets a named state holder rooted in the current StateRepository.

If the state holder existed already, it is returned with its content fully available.

Type Parameters:

K - the key type, must be Serializable

Returns:

a state holder

getPersistentStateHolder

<K extends Serializable,
V extends Serializable>
StateHolder<K,V> getPersistentStateHolder(String name,
 Class<K> keyClass,
 Class<V> valueClass,
 Predicate<Class<?>> isClassPermitted,
 ClassLoader classLoader)

Gets a named state holder rooted in the current StateRepository.

If the state holder existed already, it is returned with its content fully available.

Type Parameters:

K - the key type, must be Serializable

V - the value type, must be Serializable

Parameters:

name - the state holder name

keyClass - concrete key type

valueClass - concrete value type

isClassPermitted - Predicate that determines whether a class is authorized for deserialization as part of key or value deserialization
