Re: finding method efficiently

[Robert Schuster]

Thanks for all the replies.
I have rewritten the code that searches the methods using 
isAssignableFrom() (and feeling much better about it now).

Unfortunately it works exactly like Class.getMethod() which means 
finding put(Object, Object) is
not possible when having something else.

So it would be nice if we could write this algorithm once and for all
and make it public somewhere :-)
 

This may be a nice idea at first but for the XMLDecoder one special 
requirement spoils it. The XML
data knows no primitives but wraps them always in their respective 
class. When testing whether a given argument
type T can be assigned to a method's parameter type P I have to do 
something like this:

 if (P.isAssignableFrom(T)) -> good one, check next parameter
 else if(T.isPrimitiveWrapperClass() && 
P.isAssignableFrom(getPrimitiveTypeFor(T)) --> good one, check next 
parameter
 else -> bail out, method signature is unsuitable

This is what it makes IMHO incompatible with a general solution. :-(
