Hi! Nope, you are not using dynamic AOP. Dynamic AOP is when you add and/or
remove aspects at runtime. You can do this by hot deployment (available only in
AS) or by using our dynamic AOP API (methods addBinding and removeBinding of
class AspectManager). You can also do this by deploying and undeploying aspects
using the AspectXMLLoader class methods:
|
| public class AspectXMLLoader
| {
| // lots of other stuff
| ...
|
| // will deploy the *-aop.xml file that is located in url,
| // adding at runtime all the bindings and aspects you declared in this
file
| public static void deployXML(URL url) throws Exception
|
| // will undo the operation performed by the previous operation
| public static void undeployXML(URL url) throws Exception
|
When you add or remove aspects at runtime without hotswap enabled, JBoss AOP
will insert hooks in your code before your classes get loaded. So, there will
be empty calls to aspects on the joinpoints, including those are not being
intercepted, which can cause some delay. But it is still dynamic AOP.
If you use dynamic aop with hotswap enabled, then your code runs without
changes in its control flow. Your code will be changed only after you add an
aspect and it will be changed only in the points that are affected by that
aspect. If you remove that aspect, your code will return to its previous form,
again, without performance impact.
We are on an effort to improve our documentation and API. So, you should see a
complete documentation on this in the near future.
