Usage
The library has two main classes that the developer will work with. The first one is the class Handler and the second class is AbstractExceptionHandler. The first class is the core of the library. It is used to set custom exception handler. The second class is used to implement custom exception handler. Since the library will convert all PHP errors to exceptions, no need for the developer to have a custom errors handler.
Implementing a Custom Exceptions Handler
First step in setting a custom exceptions handler is to implement one. Implementing a custom handler is strait forward procedure. Simply, the developer have to extend the class AbstractExceptionHandler and implement one abstract method of the class. The method AbstractExceptionHandler::handle() is used to handle the exception. The developer can have access to the properties of the thrown exception in order to handle it properly. The library comes with one default exceptions handler which can act as good example in how to implement a custom handler.
Setting a Custom Exceptions Handler
After implementing the handler, the developer must set it as exceptions handler. To do that, simply the developer have to use the static method Handler::registerHandler() in any place in his project.
