EWS::baseIO

Version 1.0, April 20, 2002.

EWS::baseIO is an object-oriented basic input/output class. It provides redirectable access to console input and output, allows standard redirection, and provides a mechanism to allow output to be sent to the current console, a log file, or both.

EWS::baseIO was designed to be used as either a stand-alone object class, or as a base-class for other objects (such as EWS::htmlout). It supports full inheritence and all public methods and attributes were written to provide a straight-forward interface which may be safely overridden without harmful side effects.

EWS::baseIO provides the following class methods and attributes:
