bool gadget::BaseTypeFactory::recognizeNetDevice (  std::string    base_type ) 
 

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::BaseTypeFactory::loadNetDevice (  std::string    base_type ) 
 

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.
