Public methods

getLabResource

public void getLabResource (LabResourceRequest request, 
                StreamObserver<LabResource> responseObserver)

The gRPC request handler.

Parameters
request LabResourceRequest

responseObserver StreamObserver

notifyDeviceStateChange

public void notifyDeviceStateChange (String serial, 
                DeviceAllocationState oldState, 
                DeviceAllocationState newState)

Signals the IDeviceMonitor that a device state has been changed. Monitor implementations should limit the amount of processing and IDeviceManager/DeviceLister interaction they do in this method.

Parameters
serial String

oldState DeviceAllocationState

newState DeviceAllocationState

run

public void run ()

A method that will be called after all of the Monitor's @Option fields have been set.

setDeviceLister

public void setDeviceLister (IDeviceMonitor.DeviceLister lister)

Allows the DeviceLister to be set. After a successful attempt to set the Lister, implementations may discard all subsequent attempts.

Parameters
lister IDeviceMonitor.DeviceLister

stop

public void stop ()

A method that will be called when the Monitor need to be stopped.

Protected methods

getCachedLabResource

protected LabResource getCachedLabResource ()

Returns
LabResource
