| TraceClassVisitor | | public class TraceClassVisitor extends TraceAbstractVisitor implements ClassVisitor(Code) | | A
ClassVisitor that prints a disassembled view of the classes it
visits. This class visitor can be used alone (see the
TraceClassVisitor.main main method) to disassemble a class. It can also be used in the middle of class
visitor chain to trace the class that is visited at a given point in this
chain. This may be uselful for debugging purposes. The trace printed when
visiting the Hello class is the following:
// class version 49.0 (49)
// access flags 33
public class Hello {
// compiled from: Hello.java
// access flags 1
public <init> ()V
ALOAD 0
INVOKESPECIAL java/lang/Object <init> ()V
RETURN
MAXSTACK = 1
MAXLOCALS = 1
// access flags 9
public static main ([Ljava/lang/String;)V
GETSTATIC java/lang/System out Ljava/io/PrintStream;
LDC "hello"
INVOKEVIRTUAL java/io/PrintStream println (Ljava/lang/String;)V
RETURN
MAXSTACK = 2
MAXLOCALS = 1
}
where Hello is defined by:
public class Hello {
public static void main(String[] args) {
System.out.println("hello");
}
}
