public Class BooleanClosureWrapper

extends Object
Class Inheritance
Imports
groovy.lang.Closure, java.util.Map, .Map.Entry
Helper class for internal use only. This allows to call a Closure and convert the result to a boolean. It will do this by caching the possible "doCall" as well as the "asBoolean" in CallSiteArray fashion. "asBoolean" will not be called if the result is null or a Boolean. In case of null we return false and in case of a Boolean we simply unbox. This logic is designed after the one present in org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation#castToBoolean(Object). The purpose of this class is to avoid the slow "asBoolean" call in that method. BooleanReturningMethodInvoker is used for caching.

public <K, V> boolean callForMap(Map.Entry<K, V> entry)
