Examples of org.codehaus.groovy.runtime.callsite.BooleanReturningMethodInvoker

org.codehaus.groovy.runtime.callsite.BooleanReturningMethodInvoker
Helper class for internal use only. This allows to call a given method and convert the result to a boolean. It will do this by caching the method call as well as the "asBoolean" in {@link 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 {@link org.codehaus.groovy.runtime.typehandling.DefaultTypeTransformation#castToBoolean(Object)}. The purpose of this class is to avoid the slow "asBoolean" call in that method. The nature of this class allows a per instance caching instead of a per class caching like the normal {@link CallSiteArray} logic. @author Jochen "blackdrag" Theodorou
