void configure	(	ConfigurationParameters &	params,
		QString	prefix
	)		[virtual]

Configure the object using the ConfigurationParameters specified.

Parameters:

params	the object with configuration parameters
prefix	the group in which parameters are expected to be (this is terminated by a separator character). We expect to receive as prefix the group with mutation parameters

Reimplemented from Mutation.

void save	(	ConfigurationParameters &	params,
		QString	prefix
	)		[virtual]

Save the actual status of parameters into the ConfigurationParameters object passed.

Parameters:

params	the configuration parameters object on which save actual parameters
prefix	the prefix to use to access the object configuration parameters.
