C# 클래스 Grafiti.GestureRecognizer

Base class of gesture recognizers (GRs). A GR, that is dynamically instantiated by Grafiti, processes data of a single instance of the class Group for the recognition of a gesture. In case of successful recognition the GR can be enabled to send gesture events to the registered listeners. A GR can be parametrized through a configuration at the time of registration of a handler.

GestureRecognizer ( GRConfiguration configuration ) : System
Process ( List traces ) : void

The main function that will process the user input. It will be called on every refresh of the TUIO messages.

메소드 설명
AppendEvent ( GestureEventHandler ev, GestureEventArgs args ) : void

Use this method to send events. If the GR is not armed (e.g. it's in competition with other GRs), events will be scheduled in a queue and raised as soon as the GR will be armed. If the GR is already armed, events are raised immediately.
OnTerminating ( ) : void

Called when the GR is going to be removed from the list of active GRs and thus it won't be called anymore. Override this to handle the finalization of the GR if needed, like terminating threads, freeing resources, send terminating events... From now on, recognition state transitions will be in fact ignored. Note: at least one of the following reasons causes this method to be called: - the GR has been explicitly put in the 'terminated' state through one of the relative methods called in its Process function - the group ceased to be active i.e. all the fingers have been removed for a sufficient time, such that the traces can't be reset anymore - an exclusive GR with precedence has won In case of an LGR the following reasons are also possible: - its target has been removed from the group's LGR-list - an LGR with different target has the precedence and has won
