Class PolymorphicMethodRef

java.lang.Object

soot.SootMethodRefImpl

soot.PolymorphicMethodRef

All Implemented Interfaces:

SootMethodInterface, SootMethodRef

public class PolymorphicMethodRef
extends SootMethodRefImpl

Special class to treat the methods with polymorphic signatures in the classes MethodHandle and VarHandle. As described in https://docs.oracle.com/javase/specs/jls/se11/html/jls-15.html#jls-15.12.4.4 method references to the methods with a polymorphic signature, which are the methods in `java.lang.invoke.MethodHandle` and `java.lang.invoke.VarHandle`, require special treatment

                            boolean isStatic)

Constructor.

Parameters:

declaringClass - the declaring class. Must not be null

name - the method name. Must not be null

parameterTypes - the types of parameters. May be null

returnType - the type of return value. Must not be null

isStatic - the static modifier value

Method Detail

handlesClass

public static boolean handlesClass(SootClass declaringClass)

Check if the declaring class "has the rights" to declare polymorphic methods http://docs.oracle.com/javase/specs/jls/se11/html/jls-15.html#jls-15.12.4.4

Parameters:

declaringClass - the class to check

Returns:

if the class is allowed according to the JVM Spec

handlesClass

public static boolean handlesClass(String declaringClassName)

resolve

public SootMethod resolve()

Description copied from interface: SootMethodRef

Resolves this method call, i.e., finds the method to which this reference points. This method does not handle virtual dispatch, it just gives the immediate target, which can also be an abstract method.

Specified by:

resolve in interface SootMethodRef

Overrides:

resolve in class SootMethodRefImpl

Returns:

The immediate target if this method reference
