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

Example 1 with SimpleRemapper

use of org.objectweb.asm.commons.SimpleRemapper 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.
    for (Iterator<?> it = classToMerge.fields.iterator(); it.hasNext(); ) {
        // 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$0" field to convert the static nested class
        // into a non-static inner class. However, that approach is not
        // compatible with plain-old Java compilation. Now, Drill generates
        // the nested classes as non-static inner classes. As a result, we
        // do not want to copy the hidden fields; we'll end up with two if
        // we do.
        FieldNode field = (FieldNode) it.next();
        if (!field.name.startsWith("this$")) {
            field.accept(this);
        }
    }
    // add all the methods that we to include.
    for (Iterator<?> it = classToMerge.methods.iterator(); it.hasNext(); ) {
        MethodNode mn = (MethodNode) it.next();
        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")));
