Logtalk - Object oriented extension to Prolog
Release 2.23.0
Copyright (c) 1998-2005 Paulo Moura. All Rights Reserved.
To load this example and for sample queries, please see the SCRIPT file.
If your Prolog compiler does not support a module system, then edit the
loader.lgt file and comment out the directive that loads the module code.
In case your Prolog compiler supports a module system, you may need to
edit the code on the module.pl file and make any necessary compatibility
changes.
This folder provides simple benchmarks for comparing Logtalk message
sending performance with direct calls to Prolog predicates and with
calls to module predicates. These benchmarks may also be used for
comparing Logtalk message sending performance across Prolog compilers.
This example is made of four source files:
benchmark.pl
contains the benchmark predicates
plain.pl
contains a definition for a list length predicate
module.pl
contains the same definition of a list length predicate
encapsulated in a module
object.lgt
encapsulated in an object
The Prolog files above are loaded (from the loader.lgt file) by using
ensure_loaded/1 directives. If this directive is not supported on your
Prolog compiler, replace them by calls to the built-in predicate used
by your compiler to load Prolog code.
