Example 3 with AnnotationVisitor

use of org.objectweb.asm.AnnotationVisitor in project android_frameworks_base by ParanoidAndroid.

the class DelegateMethodAdapter2 method generateDelegateCode.

/**
     * Generates the new code for the method.
     * <p/>
     * For native methods, this must be invoked directly by {@link DelegateClassAdapter}
     * (since they have no code to visit).
     * <p/>
     * Otherwise for non-native methods the {@link DelegateClassAdapter} simply needs to
     * return this instance of {@link DelegateMethodAdapter2} and let the normal visitor pattern
     * invoke it as part of the {@link ClassReader#accept(ClassVisitor, int)} workflow and then
     * this method will be invoked from {@link MethodVisitor#visitEnd()}.
     */
public void generateDelegateCode() {
    /*
         * The goal is to generate a call to a static delegate method.
         * If this method is non-static, the first parameter will be 'this'.
         * All the parameters must be passed and then the eventual return type returned.
         *
         * Example, let's say we have a method such as
         *   public void myMethod(int a, Object b, ArrayList<String> c) { ... }
         *
         * We'll want to create a body that calls a delegate method like this:
         *   TheClass_Delegate.myMethod(this, a, b, c);
         *
         * If the method is non-static and the class name is an inner class (e.g. has $ in its
         * last segment), we want to push the 'this' of the outer class first:
         *   OuterClass_InnerClass_Delegate.myMethod(
         *     OuterClass.this,
         *     OuterClass$InnerClass.this,
         *     a, b, c);
         *
         * Only one level of inner class is supported right now, for simplicity and because
         * we don't need more.
         *
         * The generated class name is the current class name with "_Delegate" appended to it.
         * One thing to realize is that we don't care about generics -- since generic types
         * are erased at build time, they have no influence on the method name being called.
