Introduction
Using getter/setter methods gives the advantage of type hinting all data being set. Thus any data object will be transparent and easy to use without the need of additional documentation, for example the API client you're writing.
Getters & Setters
Defining A Getter
To define a getter, simply create a get...() method on your data object
Defining A Setter
To define a setters, simply create a set...() method on your data object
Serializing Objects & Collections
Serializing To Arrays
To convert a value object and its nested objects/collections to an array, you can use the toArray method. This method is recursive, so all attributes will be converted to arrays:
Serializing To JSON
To convert a value object and its nested objects/collections to a JSON object, you can use the toJson method. This method is recursive, so all attributes will be converted into JSON:
Collections
In some cases you may want to have a collection of multiple data objects. By extending the provided DataTransferObjectColletion class, you can easily set up a group of DTOs
Auto completion for collections
By overriding the current() method and setting the return value, you can enable type hinting.
Helpers
There are a few helper methods to provide some extra functionality
only()
except()
Immutability
These helpers are immutable, which means they wont affect the original data transfer object.
Example
Using the data objects is made as simple as possible
