class needs to refer a different class

[Skaperen]

right.

i am thinking i should just have functions zopen, ztopen, and topen to pass the varying parameters to the class. the difficulty is the complex relation of the file name to the sequence of (de)compression opens to be done for files that are multiply compressed. i know i can set that up in a function, but making it all into a single class that can close() them all in the right order is really messy.

and, i am looking at making zpopen() that sets up the compress as process for better performance in certain cases.

and, yes, i really do have a few multiply compressed files. i originally was wondering in any of the (de)compression classes have issues with multiple instances of itself for the same file. they shouldn't. they didn't. gzip.open() really can open against another instance of itself (for "foo.gz.gz") just fine.
