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

V - the value type, must be Serializable

Parameters:

name - the state holder name

keyClass - concrete key type

valueClass - concrete value type

Returns:

a state holder

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

classLoader - class loader used at the time of deserialization of key and value

Returns:

a state holder
