Detailed Description

The GlsMenuAction class provides a meta-data action (callback) containing an identifier of the action to perform as a meta-data item name and whose value is the parameters to pass to the action.

The static portions of the class provide the mechanism for registering handlers for specific actions.

If an action has no handler, it is a no-op.

Constructor & Destructor Documentation

GlsMenuAction::GlsMenuAction	(	const std::string &	name,
		GlsMenuDictionary &	dataDict,
		HandlerCont_t &	actionHandlers
	)

Class constructor.

Parameters

name	the name of the group of data items.
dataDict	the menu data dictionary used to evaluate menu data variables
actionHandlers	These are handlers for menu actions passed in by the creator. These are considered local to the menu set.

virtual GlsMenuAction::~GlsMenuAction ( )

virtual

Class destructor.

Member Function Documentation

virtual void GlsMenuData_T< std::string >::Attach ( std::string *& data )

virtualinherited

Attaches an external pointer to the data so that dereferencing the pointer will allow access to the data item's value without performing dictionary lookups and data value retrievals.

bool GlsMenuAction::CanExecute ( std::string & statement ) const

protected

Determine if there is a condition in front of the action to perform and if so, evaluate the condition and return the result. If there is no condition, true is returned.

virtual void GlsMenuAction::Execute ( ) const

virtual

Invoke all actions associated with the instance. Derived classes can override this method to add new action types.

Parameters

dict	data dictionary to use for evaluating action parameters.

Reimplemented in GlsMenuActionGroup.

virtual void GlsMenuData::Inc ( long amount = 1 )

virtualinherited

Increment the data item. Derived classes must override this as the default is a no-op.

Reimplemented in GlsMenuDiscrete_T< T >.

Referenced by GlsMenuSet_T< MenuType_t, DataFactory_t >::IncData().

virtual bool GlsMenuLine::OkToWrite ( )

virtualinherited

Returns false if the string is empty.

virtual std::istream& GlsMenuLine::ReadValue ( std::istream & instr )

virtualinherited

Read the stream until an end of line is encountered.

Reimplemented from GlsMenuData_T< std::string >.

Reimplemented in GlsMenuActionGroup.

virtual bool GlsMenuData_T< std::string >::ReferTo ( std::string & data )

virtualinherited

Changes the data item to refer to and use the external variable rather than its own memory. Allows access to the data item's value without performing dictionary lookups and data value retrievals.

static void GlsMenuAction::Register	(	const std::string &	name,
		ActionHandler_t *	handler
	)

static

Register a handler for a specific action.

Parameters

name	action name
handler	handler for the action

virtual void GlsMenuData_T< std::string >::ResetValueChanged ( )

virtualinherited

Sets the previous value to the current value.

void GlsMenuData_T< std::string >::SetPrecision ( int outputPrecision )

inherited

Allows for setting of precision for floating point numbers. This is the number of digits to be shown after the decimal point.

virtual const std::string & GlsMenuData_T< std::string >::Value ( ) const

virtualinherited

Returns the value of the simulation meta-data.

virtual std::string & GlsMenuData_T< std::string >::Value ( )

virtualinherited

Returns a reference value of the simulation meta-data.

virtual void GlsMenuData_T< std::string >::Value ( const std::string & val )

virtualinherited

Sets the value of the simulation meta-data.

virtual bool GlsMenuData_T< std::string >::ValueChanged ( )

virtualinherited

Determines if the value has changed since the last call to this method.

virtual std::ostream& GlsMenuData_T< std::string >::WriteValue ( std::ostream & outstr )

virtualinherited

Writes the value to the output stream.

Reimplemented in GlsMenuActionGroup.
