	Template method pattern - Wikipedia, the free encyclopedia
		In software engineering, the template method pattern is a design pattern.
		A template method defines the skeleton of an algorithm in terms of abstract operations which subclasses override to provide concrete behavior.
		First a class is created that provides the basic steps of an algorithm by using abstract methods.

	Zend Technologies - PHP 5 Feature Spotlight - The Template Method Pattern in PHP 5 (Site not responding. Last check: 2007-11-03)
		The Template Method design pattern lets subclasses redefine certain steps of an operation that are outlined in a common parent class, without changing the operation's structure.
		A Template Method can be used to implement the invariant parts of an operation, leaving the implementation of variable behavior to subclasses.
		This is achieved by declaring methods for which the redefinition is mandatory as abstract and methods for which the redefinition is optional as protected with an empty method body.

	Pattern Template Method - Web Application Component Toolkit
		The Template Method is a Gang Of Four pattern which could also be described as the frameworkers pattern: essentially it’s an application of polymorphism.
		The general approach of the template method is to define a set of general class methods which subclasses can (perhaps optionally) override the template method with a different implementation.
		The Template Method is used extensively in the WACT Template Component Architecture, allowing customizable tag components to be defined at compile time, which write specific code into the compiled template.

	Template Method (Site not responding. Last check: 2007-11-03)
		Template Method lets subclasses redefine certain steps of an algorithm without changing the algorithm's structure.
		The Template Method defines a skeleton of an algorithm in an operation, and defers some steps to subclasses.
		Template Method uses inheritance to vary part of an algorithm.

	The Template Design Pattern
		The invariant behaviour is placed in the abstract class (template) and then any subclasses that inherit it can override the abstract methods and implement the specifics needed in that context.
		The helper methods in this case might be compare() (compares two objects and returns the one that is "higher") and sortPass() (performs one iteration of a particular sorting algorithm) The interesting thing is that the usual control structure of object calls and relations is reversed.
		It is the parent class that calls the method in the subclass, a behaviour which Richard E. Sweet refers to as the "Hollywood Principle" -- "Don't call us, we'll call you." The Template Design Pattern is of particular use in the Factory Design Pattern.

	CA Security Advisor Center Glossary
		Known as the path order companion method or the path precedence companion method, it depends on a copy of the virus being made in a directory earlier in the path than the directory housing the target.
		Should a normal template contain any auto macros that should run when such a template is loaded, they are run, any menu or shortcut customizations it contains are applied, and any system macros or standard event handler macros in the template will become active, running when the corresponding Word command or event occurs.
		Infection of global templates is thus an attractive proposition to macro viruses written for such application environments, as it provides a simple form of 'residency'.

	Design Patterns in ColdFusion: Template Method Pattern @ COLDFUSION DEVELOPER'S JOURNAL (Site not responding. Last check: 2007-11-03)
		It means that the Template Method pattern is firmly rooted in the principles of two major OOP concepts: inheritance and polymorphism.
		The Template Method pattern is one of the most important concepts for those unfamiliar with OOP and design patterns because it relies so heavily on, and encourages the use of, inheritance and polymorphism.
		The Template Method pattern is most useful when you have two or more different components (custom tags, CFCs) that duplicate a significant portion of each other's code yet do not reuse or share any portion of this code through custom tags, CFIncludes, or CFCs.

		Design patterns are lessons that have been accumulated in the community of computer programming.
		A design pattern is an abstraction of the best solutions for a particular class of problems.
		It is important that patterns accompany a name because it makes possible to describe problems, solutions and talk about them with other folks.

	O'Reilly Open Source Software Convention 2003
		Of all Design Patterns presented in the classic "Gang of Four" book, "Template Method" is among the most useful.
		Python supports it, of course, but it also affords two even more powerful variants: [1] the base-class method may rely on data which a subclass can "override"; [2] the base-class method may use introspection in order to find out exactly which other methods the subclass has chosen to implement.
		Martelli's talk illustrates the pattern itself, its variants, their usage (with examples from the standard Python library), and advanced implementation techniques, including the possibility of using metaclasses for the pattern's implementation, and of using the pattern itself in metaclasses as well as base classes.
