General talk about software patterns

[<somasundram.balakrushnan AT wipro.com>]

 As far as I understand, Strategy classes are generally stateful but
they don't impose any such limitation; an implementor is free to choose
to have the Strategy class either stateful or stateless as applicable.
The context used in Strategy carries information on which the varying
algorithms can act upon. So if the state would be required for the
algorithms, then the context could include the state information as part
of it.

Just my 2 cents :-)

Thanks, Soms.

Hello

I have a question about strategy pattern. Can strategy
classes be stateful or they are generally stateless?
