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

Type Parameters:

T -

All Implemented Interfaces:

org.mule.runtime.api.lifecycle.Initialisable, ExpressionBasedValueResolver<org.mule.runtime.api.metadata.TypedValue<T>>, ValueResolver<org.mule.runtime.api.metadata.TypedValue<T>>

public class ExpressionTypedValueValueResolver<T>
extends ExpressionValueResolver<org.mule.runtime.api.metadata.TypedValue<T>>
implements org.mule.runtime.api.lifecycle.Initialisable

A ValueResolver implementation and extension of TypeSafeExpressionValueResolver which evaluates expressions and tries to ensure that the output is always of a certain type.

This ValueResolver will return the TypedValue of the expression evaluation result.

Since:

4.0
