Dependency Injection

Dependency Injection manages dependencies for you, as the name implies.

This class can be accessed by extending the base Controller class, as the property crispySystem.

! Note ! The parameters in a method or function should be type-hinted in order for this to work.

Create instance

The createInstance method takes the name of a class (including namespace) as argument. It resolves any dependencies for the constructor recursively, and returns the class instance.

This method always creates a new instance, in comparison to the getInstance method which will re-use a previously created instance, or creates a new one if it doesn’t exist.

Get instance

The getInstance method takes the name of a class (including namespace) as argument. It resolves any dependencies for the constructor recursively, and returns the class instance.

This method will re-use a previously created instance, or create a new one if it doesn’t exist.

Resolve closure

The resolveClosure method can be used to resolve dependencies in a closure. It takes one parameter, which should be a closure.

Resolve method

The resolveMethod method can be used to resolve a specific method of an instance, it takes the following arguments:

• instance, the instance of which you want to resolve a method
• method, the name of the method to resolve
• parameters (optional), if given, any parameters you give in this associative array, where the key = the name of the parameter, and the value the value, will be used to fill parameter slots. If a value is not given, the default will be used or resolved.
