Inheritance diagram for IDEA::PslParameterImpl:

List of all members.

Public Methods
	~PslParameterImpl ()
	Destructor.
void	activateFlagConstraint (const PslParameter *parameter, int authority)
	Activates (and creates if required) the value-received constraint.
void	deActivateFlagConstraint ()
	De-activates the value received constraint.
bool	finalize ()
void	reset (const IntVector &authorities)
	Resets the invoking parameter content variable.
const PslVariable *	getObservedValue ()
	An intermediate variable used only for parameters of type return-flag and return-status-flag.
const PslArgument *	getArgument () const
	Returns the argument associated with the invoking instance.
const PslVariable *	getContent ()
	Returns the content of the invoking instance.
const PslToken *	getToken () const
	Returns the token associated with the invoking isntance.
bool	receivedValue (const std::string &value)
	Sets the content of the invoking parameter to value and the actual value of the corresponding flag to true. The type of the value will be marshalled to the correct type of the content-variable.
void	print (std::ostream &os)
	Stream information of the invoking instance to os.
Protected Methods
	PslParameterImpl (const PslToken *token, const PslArgument *argument)
	Constructor.
Private Methods
virtual const PslVariable *	createContentVariable ()=0
	Creates a content variable, should contain all the values of this->getArgument()->getDomain().

Constructor.

Member Function Documentation

void IDEA::PslParameterImpl::activateFlagConstraint (  const PslParameter *    parameter, int    authority )

Activates (and creates if required) the value-received constraint.

virtual const PslVariable* IDEA::PslParameterImpl::createContentVariable (    )  [private, pure virtual]

Creates a content variable, should contain all the values of this->getArgument()->getDomain(). Implemented in IDEA::PlasmaParameterImpl.

virtual const PslVariable* IDEA::PslParameterImpl::createObservedValueVariable (    )  [private, pure virtual]

Creates an observed value variable, should contain all the values of this->getArgument()->getDomain(). Implemented in IDEA::PlasmaParameterImpl.

void IDEA::PslParameterImpl::deActivateFlagConstraint (    )

De-activates the value received constraint.

bool IDEA::PslParameterImpl::finalize (    )

const PslArgument * IDEA::PslParameterImpl::getArgument (    )

Returns the argument associated with the invoking instance.

const PslVariable * IDEA::PslParameterImpl::getContent (    )

Returns the content of the invoking instance.

const PslVariable * IDEA::PslParameterImpl::getObservedValue (    )

An intermediate variable used only for parameters of type return-flag and return-status-flag. See PslReturnReceivedConstraintImpl

const PslToken * IDEA::PslParameterImpl::getToken (    )

Returns the token associated with the invoking isntance.

void IDEA::PslParameterImpl::print (  std::ostream &    os )

Stream information of the invoking instance to os.

bool IDEA::PslParameterImpl::receivedValue (  const std::string &    value )

Sets the content of the invoking parameter to value and the actual value of the corresponding flag to true. The type of the value will be marshalled to the correct type of the content-variable. Raises an error if invoked on a parameter whose argument is not return or return-status. Returns true if the database remains consistent otherwise returns false.

void IDEA::PslParameterImpl::reset (  const IntVector &    authorities )

Resets the invoking parameter content variable. Only resets the variable is it is a successor-selector and it has at least one constraint on it's content variable with an authority equal to one of the authorities in authorities
