Examples of org.aspectj.lang.Signature

org.aspectj.lang.Signature
Represents the signature at a join point. This interface parallels java.lang.reflect.Member.

This interface is typically used for tracing or logging applications to obtain reflective information about the join point, i.e. using the j2se 1.4 java.util.logging API
```
 aspect Logging { Logger logger = Logger.getLogger("MethodEntries"); before(): within(com.bigboxco..*) && execution(public * *(..)) { Signature sig = thisJoinPoint.getSignature(); logger.entering(sig.getDeclaringType().getName(), sig.getName()); } } 
```
More detailed information about a specific kind of signature can be obtained by casting this Signature object into one of its more specific sub-types available in org.aspectj.lang.reflect. @see java.lang.reflect.Member @see java.util.logging.Logger

        if (signature instanceof MethodSignature) {
            final MethodSignature methodSignature = (MethodSignature) signature;
            isVoidReturnType = (methodSignature != null) ? Void.TYPE.equals(methodSignature.getReturnType()) : false;
        }
