PVLibraries

Extends \PVStaticObject

PVLibraries is designed to load external libraries into the system, especially those that are not in a management service like Composer.

While tools like composer make including and accessing libraries easy, not every library is on the service nor does every project want to manage their 3rd parties libraries in the same way. PVLibraries primary focus is the loading of external libraries to be used in your application.

Example:

//Initialize the class
PVLibraries::init();

//Add an external library
PVLibraries::addLibrary('MailLoader', array('path' => '/absolute/path/to/library/1', 'explicit_load' => true));

//Add a library with name spaces
PVLibraries::addLibrary('Facebook', array('path' => '/absolute/path/to/library/2', 'namespaced' => true));

//To your application to load these libraries for use
PVLibraries::loadLibraries();

Methods

Uses the magic method __call and executes a closure/anonymous function that has been added to the classes $_methods using the addMethod() method.

Adapters allows a method to be completely overwritten by calling a different class with the same method name. Adapters can also be used with closures. The adapter uses a strategy/adapter design pattern.

inherited static
access

public
todo

add ability to adapt singleton class

Arguments

string

The class that contains the function the adapter will respond too

$options

An array of options that be called -'object' string : Assumes that default method in the class to be called is static. If called object needs to be instantiated, change to object to 'instance' and one will be created before the adapter calls the function -'call_method' string: By default the method to be called to override the current one should be the same name. But this can be ovveridden to call a different method. -'type' string: The type of method being called. Default is class_method but if the method is a closure, set the type to be 'closure' and make the $trigger_method the closure

Will add an adapter for every method in the trigger_class to another class. The method will only be adapted to another class if the method in the trigger class has an adapter. This functionality can be very similiar to DI.
