Examples with MethodRemapper org.objectweb.asm.commons.MethodRemapper used on opensource projects

Example 1 with MethodRemapper

use of org.objectweb.asm.commons.MethodRemapper in project drill by apache.

the class MergeAdapter method visitEnd.

@Override
public void visitEnd() {
    // add all the fields of the class we're going to merge.
    // Special handling for nested classes. Drill uses non-static nested
    // "inner" classes in some templates. Prior versions of Drill would
    // create the generated nested classes as static, then this line
    // would copy the "this$0" field to convert the static nested class
    // into a non-static inner class. However, that approach is not
    // compatible with plain-old Java compilation. Now, Drill generates
    // the nested classes as non-static inner classes. As a result, we
    // do not want to copy the hidden fields; we'll end up with two if
    // we do.
    classToMerge.fields.stream().filter(field -> !field.name.startsWith("this$")).forEach(field -> field.accept(this));
    // add all the methods that we to include.
    for (MethodNode mn : classToMerge.methods) {
        if (mn.name.equals("<init>")) {
            continue;
        }
        String[] exceptions = new String[mn.exceptions.size()];
        mn.exceptions.toArray(exceptions);
        MethodVisitor mv = cv.visitMethod(mn.access | Modifier.FINAL, mn.name, mn.desc, mn.signature, exceptions);
        if (verifyBytecode) {
            mv = new CheckMethodVisitorFsm(api, mv);
        }
        mn.instructions.resetLabels();
        // mn.accept(new RemappingMethodAdapter(mn.access, mn.desc, mv, new
        // SimpleRemapper("org.apache.drill.exec.compile.ExampleTemplate", "Bunky")));
        ClassSet top = set;
