Class Scheduler

java.lang.Object
  org.netbeans.modules.parsing.spi.Scheduler

public abstract class Scheduler
extends Object

Scheduler defines when tasks should be started. Some SchedulerTasks (like syntax coloring) are current document sensitive only. It means that such SchedulerTask is automatically scheduled when currently edited document is changed. Other tasks may listen on different events. Implementation of Scheduler just listens on various IDE events, and call one of schedule() methods when something interesting happens. Implementation of Parsing API just finds all SchedulerTasks registerred for this Scheduler and reschedules them. Implementation of this class should be registerred in your manifest.xml file in "Editors/your mime type" folder.
