void CudaSaliency::paramChanged	(	ModelParamBase *const	param,
		const bool	valueChanged,
		ParamClient::ChangeStatus *	status
	)			`[virtual]`

Called whenever a ModelParamBase has its value changed.

Subclasses of ModelComponent should override this function if they need to do any internal reconfiguration when their parameters change value (whether due to a command-line option, or a setModelParamString(), or a readParamsFrom()). See OrientationChannel::paramChanged() in Channels/OrientationChannel.C for an example; also see SaccadeControllerConfigurator::paramChanged() in Neuro/SaccadeControllers.C for for how to use this to select subcomponents at runtime.

Parameters:

	param	the address of the ModelParamBase that changed; subclasses can compare this with the addresses of their model param members to figure out which is the relevant param
	valueChanged	true if the value actually changed, false if the value was "set" but the new value is the same as the old value; some clients may want to avoid re-doing expensive operations if the value did not actually change
	status	the subclass that implements paramChanged() should set status to CHANGE_REJECTED if it wishes to reject a particular parameter change; the caller of paramChanged() is expected to set status to CHANGE_ACCEPTED prior to calling paramChanged(), so the implentation of paramChanged() does not need to set *status CHANGE_ACCEPTED if it wishes to allow the change since that will already be the default status

HISTORICAL NOTE: In the past, subclasses would override setModelParamString() for this same purpose, but in the new setup, setModelParamString() is NOT virtual and hence should not be (cannot be) overridden by subclasses. This setup is cleaner (and potentially more efficient) because subclasses don't have to compare string names to figure out which param changed; instead they are passed the address of the param itself. Furthermore, the new setup is more robust, since we can handle param value changes that come from any source (e.g., setModelParamVal(), or ModelParamBase::setValString(), or OModelParam::setVal()), and not just those that come through setModelParamString().

Reimplemented from ModelComponent.
