BooleanClosureWrapper (Groovy 5.0.7)
Description: declaration: package: org.codehaus.groovy.runtime.callsite, class: BooleanClosureWrapper

Package org.codehaus.groovy.runtime.callsite

# Class BooleanClosureWrapper

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

public class BooleanClosureWrapper extends Object
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 `DefaultTypeTransformation.castToBoolean(Object)`. The purpose of this class is to avoid the slow "asBoolean" call in that method. `BooleanReturningMethodInvoker` is used for caching.

    normal closure call

  - ### callForMap

    public <K, V> boolean callForMap(Map.Entry<K,V> entry)
    Bridge for a call based on a map entry. If the call is done on a `Closure` taking one argument, then we give in the `Map.Entry`, otherwise we will give in the key and value.
