Singleton

Test::Singleton is a test for Singleton classes. SYNOPSIS use Test::More tests => 1; use Test::Singleton; is_singleton( "Some::Class", "new", "instance" ); ** If you are unfamiliar with testing read Test::Tutorial first! ** This is asimple, basic module for checking whether a class is a...

This script is an implementation of the singleton without using the __new__ class but by implementing the __call__ method in the metaclass.

This script contains a class that shows how to implement the singleton pattern in Python. A singleton is a class that makes sure only one instance of it is ever created. Typically such classes are used to manage resources that by their very nature can only exist once.

This script creates a unique instance of classes that uses Singleton as their metaclass. Used as a metaclass, Singleton replaces a class with a unique class instance. Any subsequent calls to the class's constructor will result in an exception, as the constructor is overwritten immediately after...

EOG Correction program is used to work out the amount of ocular potential recorded by the electroencephalograph [EEG] (as a proportion of the potentials recorded by the electrooculograph [EOG]), and to subtract this from the EEG. By doing this we are able to reduce the effect of ocular potentials...
