Constructor Details

#initialize(args = {}) ⇒ Context

Instances of a defined subclass of Context are initialized checking first that all subclass defined roles are provided in the creation invocation raising an error if any of them is missing. Once the previous check is met, every object playing in the context instance is associated to the stated role. Non players args are associated to instance_variables and readers defined.
