RulerZ is a PHP implementation of the Specification pattern which puts the emphasis on three main aspects: - an easy and data-agnostic DSL to define business rules and specifications, - the ability to check if a candidate satisfies a specification, - the ability to filter or query any datasource to only retrieve candidates matching a specification.

|
Purpose
|
|
-------
|
|
|
|
Builds a clear specification of business rules, where objects can be
|
|
checked against. The composite specification class has one method called
|
|
``isSatisfiedBy`` that returns either true or false depending on whether
|
|
the given object satisfies the specification.
