Class ValidationFunctions

java.lang.Object

org.mule.extension.validation.internal.el.ValidationFunctions

public final class ValidationFunctions
extends Object

A class which allows executing instances of AbstractValidator's from a MEL context.

Unlike regular validations which throw an exception upon failure, the methods in this class will only return boolean values to indicate if the validation was successful or not. Also, no message is returned in either case.

Since in this case we only care about the boolean result of the validation, all validations will be executed with the same ValidationContext

Validator instances are not reused. A new one is created each time

Since:

1.0
