Workshop Title: The Visitor Pattern
----------------------------------------------------------------------
Workshop Abstract: The intent of the Visitor Pattern is to represent an
operation to be performed on the elements of an object structure.
Visitor lets you define a new operation without changing the classes of
the elements on which it operates. The following links show some
examples of how the Visitor structure can be implemented in Java.

This workshop will introduce the Visitor pattern, and then try to
address the question of whether the Visitor pattern is a useful concept
for everyday programming. Rather than a long presentation the focus
will be on whiteboarding and creating opportunities for participants to
discuss their experiences with the Visitor pattern and particular code
design issues.

The Visitor pattern is intended to get us started. Future workshops
will not be restricted to design patterns, but open to any topic related
to generic programming issues. The content of future workshops will
depend on what people are interested in presenting.
