| [aspectj-users] trying to write a simple caching aspect |
|
Hi – I am new to aspectj, I am working through some example and trying to develop a few aspects as a proof of concept. The first aspect I am trying to develop is a real simple caching aspect which caches objects based on the implementation of a tag interface.
What I would like to do is when a constructor is called, check if the class implements an interface, if it does check the cache. If there is no reference in the cache, proceed, cache the object and then return it. Otherwise return the cached instance.
What I need to be able to do is get the name of the class the constructor is being called on. My pointcut should really select all constructors in the system (maybe confined to a package) with any number of arguments. Once I have the class object or the name, I can determine if the cache should be consulted.
Is this possible? If so could someone provide me with an example of the pointcut and advice. I would provide what I have already but I am stumped as to how I can capture class of the object I am trying to instantiate. My problem is I would like to capture the class as context in an around advice using a target() like construct.
Thanks in advance. Jody b.
