Class RegistryLookupValueResolver<T>

java.lang.Object

org.mule.runtime.module.extension.internal.runtime.resolver.RegistryLookupValueResolver<T>

All Implemented Interfaces:

ValueResolver<T>

public class RegistryLookupValueResolver<T>
extends Object
implements ValueResolver<T>

Implementation of ValueResolver which accesses the mule registry and returns the value associated with key.

Although the registry is mutable, isDynamic() will always return false since the value associated to a given key is not meant to change.

The registry is accessed through the MuleContext that is exposed in the Event that is passed to the resolve(Event) method

Since:

3.7.0
