Class DynamicConfigurationInstanceProvider<T>

java.lang.Object

org.mule.module.extension.internal.runtime.DynamicConfigurationInstanceProvider<T>

All Implemented Interfaces:

org.mule.extension.runtime.ConfigurationInstanceProvider<T>

public final class DynamicConfigurationInstanceProvider<T>
extends Object
implements org.mule.extension.runtime.ConfigurationInstanceProvider<T>

A ConfigurationInstanceProvider which continuously evaluates the same ResolverSet and then uses the resulting ResolverSetResult to build an instance of a given type.

Although each invocation to get(OperationContext) is guaranteed to end up in an invocation to #resolverSet#resolve(MuleEvent), the resulting ResolverSetResult might not end up generating a new instance. This is so because ResolverSetResult instances are put in a cache to guarantee that equivalent evaluations of the resolverSet return the same instance.

Since:

3.7.0
