Abstract
In some situations a parameter to a method or function may be costly to process or evaluate, but might only need to be processed or evaluated in certain situations. It is therefore useful to allow for lazy evaluation of such parameters. This results in an on demand evaluation model that may have significant performance or processing benefits.
