README
Provides a basic set of classes to utilize the specification design pattern.
Usage
The included tests provide common usage of the classes.
Basic Usage
Upon creating your specification classes, simply extend the AbstractSpecification
class
and implement the isSatisfiedBy
method.
Any specifications that you create are flexible enough to take in any arguments in the constructor, such as repositories or services.
In addition, an isNotSatisfiedBy
method is provided to provide a logical not if
needed.
Composite Usage
When you need to chain multiple specifications on the same object, you can leverage the
AbstractSpecification
chain methods plus
and either
.
For example:
(new CustomerIsPremium()) ->either(new CustomerRegisteredBeforeLastWeek()) ->isSatisfiedBy($customer);
or
(new CustomerIsPremium()) ->plus(new CustomerRegisteredBeforeLastWeek()) ->isSatisfiedBy($customer);
