Hello *
I think I will give a glimpse of scenario of my problem so that
we can discuss and conclude which will be the best design pattern
Here is the scenario:
I have 3 types of trace files (A , B, C) each has
its own format and requires a different way of parsing the file to pick
data from the file.
so Afile has a Aparser, Bfile has Bparser, and
Cfile has Cparser. apart from these Aparser, Bparser, Cparser there are
common methods
that can be reused for parsing the file.
Now the design for this:
Trace <>--------> TraceParser
/ | \ (sorry the lines
here indicate inheritance/generalization)
AparserType BparserType CparserType
Points for discussion:
1. If TraceParse has a method ParserTrace which
AparseType , BparseType , CparserType has different implementation for
it --- It is Strategy
2. If TraceParser has many methods some of them are
common for the three parser types and some of then have been overridden
by the three parser Types -
is it a template method ????
3. The input file at a point can be one of TraceType,
Trace will decided by checking the file which TraceType is it and based
on that object AparserType/
BparserType/CparserType is created
Please enlighten me , correct me so that I will learn from my
mistakes.
Thanks & Regards
Bharathi
