Custom HTTP Clients
Create a new class implementing the "ClientAdapterInterface" and return the response as PSR-7.
Set the custom client adapter to your explorer before using it.
Custom Serializers
Create a new class implementing the "SerializerInterface" and return the response.
Set the custom serializer to your explorer before using it.
Events
This library offers you some events to listen on. To use the event system you have to add the "EventManager" to your Explorer before using it.
To listen on a specific event you have to implement a Listener. A Listener is a PHP object with a public method "handle". As parameter your will get the triggered Event object.
PostClientRequestEvent
This event is called on each executed request (after following a link or using the "request" method) and contains the complete PSR-7 response.
