Detailed Description

A generic factory used to create an appropriate.

See also:

ACEXML_CharStream from a SYSTEM id. This class creates a

ACEXML_FileCharStream or a

ACEXML_HttpCharStream depending on the URI supplied.

Todo:

Write a stream abstraction for handling ftp:// type URIs and add a function to create and return such streams. That is the only chunk missing in the armour.
