Configuration method interface.

The Processing base class forces all the concrete classes derived from it to implement this method, which must actually perform the specific configuration tasks.

Note that the user can not call this method directly. He will use Configure instead. The argument is expected to be an object of the necesary concrete configuration class.

Parameters:
Referenceto the configuration object.
Returns:
false if the object is not yet fully configured. (For example, if some important configuration attribute such as number of ports was set to zero in the config object)

true if the processing object is left in a consistent state, and can be executed.

Exceptions:
Thismethod must throw a bad_cast exception if the argument is not an object of the expected configuration class.

Implemented in CLAM::SMSTransformationChain, and CLAM::TopLevelProcessing.

bool CLAM::ProcessingComposite::ConcreteStart ( void  )
protectedvirtual

Concrete start implementation, called when the user calls Start() on the Processing(Composite), should be used to implement any specific start implementation required by classes deriving from this class.

When overriding this function in a class derived from ProcessingComposite be sure to call the base class (so child Processings are properly started).

Configuration getter.

Gets the configuration parameters used to create the object.

Returns:
Const reference to the configuration object. The usual way to perform a configuration change in the processing object is to take a copy of this reference, to change it and to send it with the Configure method. If not overriden, it returns a NullProcessingConfig.
