      public UdevSubsystemMonitor(String name, String subsystem)
      Create a new systemd device subsystem monitor for the named subsystem. As this monitor will have no matchers, no devices will be exposed by this monitor. It is recommended that listeners be added before the monitor is installed. Matchers can be added before or after installation and will generate events for newly matched devices regardless.
      Parameters:
      name - monitor name for display purposes
      subsystem - the subsytsem to monitor

      Parameters:
      listener - the listener for the monitor to use

    • setAvailability

      public UdevSubsystemMonitor setAvailability(UdevDeviceAvailabilityListener listener)

    • addMatcher

      public UdevSubsystemMonitor addMatcher(UdevSubsystemMonitor.UdevDeviceMatcher matcher)
      Add a new matcher to the monitor. Any devices that match this new matcher which don't match existing matchers will generate device add callbacks. This allows matchers to be added after the subsystem is already installed.

    • removeMatcher

      public void removeMatcher(UdevSubsystemMonitor.UdevDeviceMatcher matcher)
      Remove a matcher from the monitor. Any devices that match this matcher which don't match remaining matchers will generate device remove callbacks. This allows matchers to be removed after the subsystem is already installed.

    • getDevices

      public Set<UdevDevice> getDevices()
      Return a list of devices that match this monitor.
