bool gadget::DeviceFactory::recognizeDevice

(

jccl::ConfigElementPtr

element

)

Queries if the factory knows about the given device.

Precondition:

element != NULL, element is a valid element.

Parameters:

element

The element we are requesting about knowledge to create.

Returns:

true if the factory knows how to create the device; false if not.

Input * gadget::DeviceFactory::loadDevice

(

jccl::ConfigElementPtr

element

)

Loads the specified device.

Precondition:

recognizeDevice(element) == true.

Parameters:

element

The specification of the device to load.

Returns:

NULL is returned if the device failed to load. Otherwise, a pointer to the loaded device is returned.
