Class LambdaSummaryClass

java.lang.Object
com.ibm.wala.classLoader.SyntheticClass
com.ibm.wala.ipa.summaries.LambdaSummaryClass
All Implemented Interfaces:
IClass, IClassHierarchyDweller
public class LambdaSummaryClass extends SyntheticClass
Synthetic class modeling the anonymous class generated at runtime for a lambda expression. The anonymous class implements the relevant functional interface. Our synthetic classes contain instance fields corresponding to the values captured by the lambda. The implementation of the functional interface method is a "trampoline" that invokes the generated lambda body method with the captured values stored in the instance fields.
