[aspectj-dev] dynamically disable set functions

[Candy Chiu <candy.chiu.ad@xxxxxxxxx>]

I'd want to build an aspect to dynamically disable set function based on a boolean field.

Order is a domain object which contains only getters and setters.

package org.talz;

import org.aspectj.lang.reflect.MethodSignature;

privileged public aspect DynamicSetDisabler perthis( allSetFunctions( Order ) ) {

pointcut allSetFunctions( Order order ) : 

execution( * Order.set*(..) ) && this( order )

&& !within(DynamicSetDisabler)

&& !within(sun.reflect..*);

void around( Order order ) : allSetFunctions( order ) {

if( !order.enableSet ) {

System.out.println( "Set disabled" );

} else {

System.out.println( "Set enabled" );

try {

MethodSignature method = (MethodSignature) thisJoinPoint.getSignature();

method.getMethod().invoke( order, thisJoinPoint.getArgs() );

}

catch( Exception e ) {

e.printStackTrace();

}

}

}

}

Is there a way to achieve my use case?  Thanks.
