Maybe you could just wear a silly hat. That'd be enough.
I meant - something along the lines of -
PoolableObjectFactory<T> {
void activateObject(T obj);
destroyObject(T obj);
T makeObject();
void passivateObject(T obj);
boolean validateObject(T obj);
}
Oh, I misunderstood your request: you mean that you want to use
"generics" in commons-pool.
I wasn't able to find any environment "requirements" for commons-pool,
but I suspect that the developers would like commons-pool to be usable
in pre-1.5 Java environments, where generic classes aren't available.
I have to admit that I'm not a big fan of generics in the first place...
just syntactic sugar that ends up making your code uglier than it would
be with plain-old casting.
And, in Java, you don't even get RTTI which
is really too bad :(
That has been my biggest sore-point with generics too. There are some
talks of 'reification' and similar constructs in java 7 , but i believe
it has been postponed to the next release altogether as well.
If you'd like to use commons-pool as a basis for your own tools, you can
certainly modify the source code to add lots of< and> symbols if you
want. Also, patches are always welcome :)
Good to know. Is this being actively maintained at the moment / does it
warrant a separate branch for generics ?
Commons pool is being actively maintained. As Chris points out, the
1.x versions of pool target "old" JDKs (1.3+) for backward
compatibility.
While I personally share Chris' attitude on generics, Commons
components are by and large moving to support them. For pool, that
means version 2.0, where we will also take advantage of the
concurrency enhancements in JDK 1.5+. Suggestions - ideally with
patches - for gerification of the API (as above) are welcome on the
dev list and JIRA.
Is there a branch already maintained for 2.0 or would patch against
trunk (for generics) be taken and started afresh ?
