HookMethod

A HookMethod is a method which is called from a TemplateMethod. Functionality of the TemplateMethod is shifted to the HookMethod to allow for customisation of the TemplateMethod's functionality by later (e.g. in a derived class) changing the HookMethod.

Example:

	public class Algorithm {
		public void templateMethod() {
				:
				.
			hookMethod();
				.
				:
		}

		public void hookMethod() {
			// default implementation
		}
	}

	public class RefinedAlgorithm extends Algorithm {
		public void hookMethod() {
			// refined implementation
		}
	}
