Informations about the package value-object
Value Object
PHP Interface to create value objects to use in your project. Abstract Enum class available that uses the same interface.
Why?
ValueObjects are the ideal way to use in your project. You can force yourself in your project to have data in the way you want.
Documentation
The interface
The interface has three methods you need to implement.
- __toString(): This magic method is needed to represent the ValueObject as a string. Is usefull for logging.
- toNative(): This method must return an array, integer, string... This is needed to test if two value objects are the same or not and for serializing.
- equalsTo(ValueObject $object): The method requires another ValueObject instance. The
toNative()
-method can be used to check if two value objects are the same. In the Enum it uses theequals
method from the parent.
The Enum
The included Enum extends the Enum from MyCLabs.
Additionally it implements the interface.
This way it's possible to use the functions toNative()
and equalsTo()
in your application.
More importantly an enumaration is also a value object, something that can't be changed when created.
When all those classes implements the same interface, its easier for the developer to use them through eachother.
