Hi,
I have a Clojure project which strongly uses some external java framework
(if you want to know it is Eclipse RDF4j). I need to override some method
within a java class. The issue is I am not able to inject my own
implementation of that class because it is in the middle of some complex
hierarchy.
In another Java (+ Spring Framework) project I had similar problem and I
had fixed that using AspectJ proxy which had had a breakpoint in calling a
particular java method. I read in many places that Clojure does not need it
and some explanation based on pure clojure examples. I would like to know
if Clojure is able to manage java code.
Quite often examples built a proxy with combination Java Class + protocol
and than injected the instance into somewhere. I thing that it does not
cover following example. The problems I found difficult are:
1. Distance between my code and Foo class is like 3 or 4 classes
2. Programmers quite strongly uses creation de novo rather than injection
already prepared instance
Thanks a lot for your help,
Jacek Grzebyta
++++++ java code+++++
class Baz {
// I need to proxy this method
protected List doAction(String arg 1, String arg2)
// weird work which I need to change
}
//////////////////////// Foo class
class Foo {
// cut
// elswhere
Baz jobber = new Baz(); // it creates de novo injection not supported
public String mySuperMethod(List args4) {
jobber.doAction(someList)
}
// cut
}
