evaluateIfExpression

public org.mule.runtime.api.metadata.TypedValue evaluateIfExpression(org.mule.runtime.api.event.Event event,
                                                                     Object source)

It will try to evaluate the source sent, if it's a string and a valid expression.

Parameters:

event - the event over to which evaluate

source - the variable containing the posible expression

Returns:

the source if it's not an evaluable expression, or the result of the evaluation

evaluate
