Class ContextInput

java.lang.Object
  edu.berkeley.guir.ptk.PTK
      edu.berkeley.guir.ptk.input.InputSource
          edu.berkeley.guir.ptk.input.ContextInput

All Implemented Interfaces:

context.arch.handler.Handler, java.lang.Runnable

public class ContextInput

extends InputSource

implements context.arch.handler.Handler

Gets a context event from a (running) context widget and dispatches it. The metadata of the events this class creates is ContextConstants.CONTEXT. The data IDs are dependent on the particular context widget that it is hooked up to.
