Protected Member Functions
	HardwareModule (Entity *e, const char *m_class, const char *part, const IncoTable *table=NULL, int state_size=0)
	Constructor.
virtual	~HardwareModule ()
	Destructor.
SimulationState::Type	getAndCheckState (const TimeSpec &t)
	Returns the state of the simulation at this time.
SimulationState::Type	getCurrentState ()
	Find the current state, previously calculated with getAndCheckState.
void	transitionComplete ()
	Indicate that a transition is complete.
Protected Member Functions inherited from dueca::DusimeModule
	DusimeModule (Entity *e, const char *m_class, const char *part, const IncoTable *inco_table, int state_size)
	Constructor.
virtual	~DusimeModule ()
	Destructor.
bool	snapshotNow ()
	Returns true if a snapshot has to be taken in this cycle.
virtual void	fillSnapshot (const TimeSpec &ts, Snapshot &snap, bool from_trim)
	If snapshots are generated, this has to be implemented by a descendant.
virtual void	loadSnapshot (const TimeSpec &ts, const Snapshot &snap)
	For restoring the state from an old snapshot.
void	trimCalculationCondition (TriggerPuller &cond)
	This can be used to specify the condition under which the trim calculation may take place, for example, data has to be received on trim calculation input channels.
virtual void	trimCalculation (const TimeSpec &ts, const TrimMode &mode)
	This must be overridden if the module takes part in trim condition calculations.
Protected Member Functions inherited from dueca::Module
	Module (const Entity *e, const char *m_class, const char *part)
	Constructor.
Protected Member Functions inherited from dueca::NamedObject
	NamedObject (const GlobalId &id)
	Reserve for AssociateObject.
	NamedObject (const NameSet &ns)
	Normal constructor, protected, because it has no use to create a NamedObject by itself.
virtual	~NamedObject ()
	Destructor.

Detailed Description

HardwareModule, a base class for modules that interact with hardware.

A base class from which users can derive Dusime hardware modules, i.e. modules that do the IO with physical hardware, and that thus, in addition, require extra facilities, such as:

calibration of the hardware a safety mode for driving the hardware to a safe state transitional states, e.g. for moving hardware

Constructor & Destructor Documentation

HardwareModule()

dueca::HardwareModule::HardwareModule ( Entity * e, const char * m_class, const char * part, const IncoTable * table = NULL, int state_size = 0 )

protected

Constructor.

Parameters

e	Pointer to the entity.
m_class	Module class name.
part	Part name for the module.
table	Table with initial condition calculation specification.
state_size	Size of a snapshot of the state.

Member Function Documentation

getAndCheckState()

SimulationState::Type dueca::HardwareModule::getAndCheckState ( const TimeSpec & t )

protected

Returns the state of the simulation at this time.

To be used by the child, every time a model update is calculated, for determining desired action.

transitionComplete()

void dueca::HardwareModule::transitionComplete ( )

protected

Indicate that a transition is complete.

In transitional states (e.g. Inactive_HoldCurrent, Calibrate_HoldCurrent), a HardwareModule must confirm when the transition is completed through this call.
