# Class BooleanReturningMethodInvoker

java.lang.Object
org.codehaus.groovy.runtime.callsite.BooleanReturningMethodInvoker

    public class BooleanReturningMethodInvoker
    extends java.lang.Object

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 `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 `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 `CallSiteArray` logic.
