Revision history for Perl extension Set::IntSpan
1.07 1988 Dec 03
- fixes to facilitate subclassing
o use ref $this instead of hardcoded "Set::IntSpan"
o made internal functions into methods
o use method call syntax on all internal method calls,
not function call syntax
o use direct object syntax on all internal method calls,
because indirect object syntax sometimes parses as a
function call
- added ABSTRACT and AUTHOR keys in Makefile.PL
>From the README file:
Set::IntSpan VERSION 1.07 - Manages sets of integers
DESCRIPTION
Set::IntSpan manages sets of integers. It is optimized for sets that
have long runs of consecutive integers. These arise, for example, in
.newsrc files, which maintain lists of articles:
alt.foo: 1-21,28,31
alt.bar: 1-14192,14194,14196-14221
Sets are stored internally in a run-length coded form. This provides
for both compact storage and efficient computation. In particular,
set operations can be performed directly on the encoded
representation.
Thanks to Chris Sidi for showing me how to fix the code to support
subclassing.
