Method Detail

doInitialize

protected void doInitialize()
                     throws Exception

Description copied from class: DeviceSystem

Invoked by DeviceSystem.initialize() to perform the very logic of the initialization of this DeviceSystem. This instance has been prepared for initialization by an earlier call to DeviceSystem.preInitialize() and the initialization will be completed with a subsequent call to DeviceSystem.postInitialize().

Specified by:

doInitialize in class DeviceSystem

Throws:

Exception - if an error occurs during the initialization of this instance. The initialization of this instance will be completed with a subsequent call to postInitialize() regardless of any Exception thrown by doInitialize().

toString

public String toString()

Description copied from class: DeviceSystem

Returns a human-readable representation of this DeviceSystem. The implementation of DeviceSystem returns the protocol of the MediaLocators of the CaptureDeviceInfos (to be) registered by this DeviceSystem.

Overrides:

toString in class DeviceSystem

Returns:

a String which represents this DeviceSystem in a human-readable form
