Constructor Detail

Blobfinder

public Blobfinder(DeviceNode roboClient,
                  Device device)

Creates a Blobfinder device object.

Parameters:

roboClient - The DeviceNode to which this device is connected.

device - This device' information.

Method Detail

update

protected void update()

Update the current blob count and blob information.

Overrides:

update in class Device

getBlobs

public java.util.concurrent.CopyOnWriteArrayList<BlobfinderBlob> getBlobs()

Returns:

All known blobs to this device since init.

getCount

public int getCount()
