Aspect-try-catch

It's a project that uses aspectj for creating annotaion for @Try @Catch and @Also (similar with finally)

This annotations work at an instance level.

@Try

• used to mark a method that can throw a Throwable
• can have any signature
• when it's applied, the presence of at least one @Cath method becames mandatory

@Catch

• used to mark a method than can catch a specific Throwable
• must have the same return type, method parameters as the @Try annotated method + one catch parameter that is a subclass of Throwable
• can't have multiple methods that catch the same exception type
• when mutiple methods are marked with @Catch, hierarchical priority is used ( same exception type then closest super type of exception )
• at least one method annotated when @Try is used in same class

@Also

• used to mark a method that is called after a @Try @Catch combo is executed
• it's called even if no @Catch methods could catch any exception
• void return type is mandatory
• must have same method parameters as @Try
• it is optional

Example:

@Try
public String tryMethod(String msg) {
    ...
}

@Catch
public String catchMethod1(String tryMsg, RuntimeException runtimeException) {
    ...
}

@Catch
public String catchMethod2(String message, IllegalMonitorStateException exception) {
    ...
}

@Also
public void alsoMethod(String string){
    ...
}
