How do I get a list of Methods called from a Class in Eclipse IDE?

Question

I am using Eclipse IDE for my Java project. I need a list of methods which are being called from a particular class i.e. I need to see a list of all the methods which are being

To find the methods that are called from a class (assuming programatically), I would use the ASM bytecode analyzing/manipulation library. The below example is a ClassVisitor that prints all the methods called from a class.

import org.objectweb.asm.ClassAdapter;
import org.objectweb.asm.ClassVisitor;
import org.objectweb.asm.MethodVisitor;
import org.objectweb.asm.commons.InstructionAdapter;

public class MethodCallFinder extends ClassAdapter {

    private String name;

    public MethodCallFinder(ClassVisitor classVisitor) {
        super(classVisitor);
    }

    @Override
    public void visit(int version, int access, String name, String signature, String superName, String[] interfaces) {
        this.name = name;
        super.visit(version, access, name, signature, superName, interfaces);
    }

    @Override
    public MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions) {
        return new MethodCallPrinter(super.visitMethod(access, name, desc, signature, exceptions));
    }

    private class MethodCallPrinter extends InstructionAdapter {

        public MethodCallPrinter(MethodVisitor methodVisitor) {
            super(methodVisitor);
        }

        @Override
        public void visitMethodInsn(int opcode, String owner, String name, String desc) {
            System.out.printf("Class %s calls method %s with descriptor %s from class %s%n", MethodCallFinder.this.name, name, desc, owner);
            super.visitMethodInsn(opcode, owner, name, desc);
        }
    }
}
