| AdviceAdapter | | abstract public class AdviceAdapter extends GeneratorAdapter implements Opcodes(Code) | | A
org.objectweb.asm.MethodAdapter to insert before, after and around
advices in methods and constructors. The behavior for constructors is
like this:
- as long as the INVOKESPECIAL for the object initialization has not been
reached, every bytecode instruction is dispatched in the ctor code visitor
- when this one is reached, it is only added in the ctor code visitor and
a JP invoke is added
- after that, only the other code visitor receives the instructions

| Method Summary | |
| abstract protected void | onMethodEnter()
Called at the beginning of the method or after super class class call in
the constructor. | | abstract protected void | onMethodExit(int opcode)
Called before explicit exit from the method using either return or throw. | | public void | visitCode()
| | public void | visitFieldInsn(int opcode, String owner, String name, String desc)
| | public void | visitInsn(int opcode)
| | public void | visitIntInsn(int opcode, int operand)
| | public void | visitJumpInsn(int opcode, Label label)
| | public void | visitLabel(Label label)
| | public void | visitLdcInsn(Object cst)
| | public void | visitLookupSwitchInsn(Label dflt, int[] keys, Label[] labels)

| methodAccess | | protected int methodAccess(Code) | | |
| AdviceAdapter | | public AdviceAdapter(MethodVisitor mv, int access, String name, String desc)(Code) | | Creates a new
AdviceAdapter
Parameters:
mv - the method visitor to which this adapter delegates calls.
Parameters:
access - the method's access flags (see Opcodes).
Parameters:
name - the method's name.
Parameters:
desc - the method's descriptor (see Type Type). |
| onMethodEnter | | abstract protected void onMethodEnter()(Code) | | Called at the beginning of the method or after super class class call in
the constructor.
Custom code can use or change all the local variables, but should not
change state of the stack.
|
| onMethodExit | | abstract protected void onMethodExit(int opcode)(Code) | | Called before explicit exit from the method using either return or throw.
Top element on the stack contains the return value or exception instance.
For example:
public void onMethodExit(int opcode) {
if(opcode==RETURN) {
visitInsn(ACONST_NULL);
} else if(opcode==ARETURN || opcode==ATHROW) {
dup();
} else {
if(opcode==LRETURN || opcode==DRETURN) {
dup2();
} else {
dup();
}
box(Type.getReturnType(this.methodDesc));
}
visitIntInsn(SIPUSH, opcode);
visitMethodInsn(INVOKESTATIC, owner, "onExit", "(Ljava/lang/Object;I)V");
}
// an actual call back method
public static void onExit(int opcode, Object param) {
...
Custom code can use or change all the local variables, but should not
change state of the stack.
Parameters:
opcode - one of the RETURN, IRETURN, FRETURN, ARETURN, LRETURN,DRETURN or ATHROW |
