Class LazyExpressionLanguageAdaptor

java.lang.Object

org.mule.runtime.config.internal.lazy.LazyExpressionLanguageAdaptor

All Implemented Interfaces:

ExpressionLanguageAdaptor, ExtendedExpressionLanguageAdaptor

public class LazyExpressionLanguageAdaptor
extends Object
implements ExtendedExpressionLanguageAdaptor

Defers the creation of an ExpressionLanguageSessionAdaptor until the moment in which it's actually asked to resolve an expression.

A CheckedSupplier will be used to obtain the delegate. The supplier will only be invoked once and the return value will be cached.

Since:

4.2.0
