virtual IFSelect_ReturnStatus	Do (const int number, const occ::handle< IFSelect_SessionPilot > &pilot)=0

Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.
	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.
Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.
virtual	~Standard_Transient ()=default
	Destructor must be virtual.
virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.
bool	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.
bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.
bool	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
bool	IsKind (const char *const theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
int	GetRefCount () const noexcept
	Get the reference counter of this object.
void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
virtual void	Delete () const
	Memory deallocator for transient classes.

Static Public Member Functions

	Removes a Command, if it is recorded (else, does nothing).
static bool	Select (const char *const command, int &number, occ::handle< IFSelect_Activator > &actor)
	Selects, for a Command given by its title, an actor with its command number. Returns True if found, False else.

	Returns, for a root of command title, the list of possible commands. <mode> : -1 (D) for all commands if <commands> is empty -1 + command : about a Group , >= 0 see Adding By default, it returns the whole list of known commands.

Detailed Description

Defines the general frame for working with a SessionPilot. Each Activator treats a set of Commands. Commands are given as alphanumeric strings. They can be of two main forms :

• classic, to list, evaluate, enrich the session (by itself) : no specific remark, its complete execution must be described
• creation of a new item : instead of creatinf it plus adding it to the session (which is a classic way), it is possible to create it and make it recorded by the SessionPilot : then, the Pilot will add it to the session; this way allows the Pilot to manage itself named items

In order to make easier the use of Activator, this class provides a simple way to Select an Actor for a Command : each sub-class of SectionActor defines the command titles it recognizes, plus attaches a Number, unique for this sub-class, to each distinct command title.

Each time an action is required, the corresponding Number can then be given to help the selection of the action to do.

The result of an Execution must indicate if it is worth to be recorded or not : see method Do

Member Function Documentation

Add()

void IFSelect_Activator::Add	(	const int	number,
		const char *const	command ) const

Allows a self-definition by an Activator of the Commands it processes, call the class method Adding (mode 0).

Adding()

void IFSelect_Activator::Adding ( const occ::handle< IFSelect_Activator > & actor, const int number, const char *const command, const int mode )

static

Records, in a Dictionary available for all the Activators, the command title an Activator can process, attached with its number, proper for this Activator <mode> allows to distinguish various execution modes 0: default mode; 1 : for xset.

AddSet()

void IFSelect_Activator::AddSet	(	const int	number,
		const char *const	command ) const

Same as Add but specifies that this command is candidate for xset (creation of items, xset : named items; mode 1).

Commands()

occ::handle< NCollection_HSequence< TCollection_AsciiString > > IFSelect_Activator::Commands ( const int mode = -1, const char *const command = "" )

static

Returns, for a root of command title, the list of possible commands. <mode> : -1 (D) for all commands if <commands> is empty -1 + command : about a Group , >= 0 see Adding By default, it returns the whole list of known commands.

Do()

virtual IFSelect_ReturnStatus IFSelect_Activator::Do ( const int number, const occ::handle< IFSelect_SessionPilot > & pilot )

pure virtual

Tries to execute a Command Line. <number> is the number of the command for this Activator. It Must forecast to record the result of the execution, for need of Undo-Redo Must Returns : 0 for a void command (not to be recorded), 1 if execution OK, -1 if command incorrect, -2 if error on execution.

Implemented in IFSelect_Act, IFSelect_SessionPilot, IGESSelect_Activator, and StepSelect_Activator.

const

Help()

virtual const char * IFSelect_Activator::Help ( const int number ) const

pure virtual

Sends a short help message for a given command identified by it number for this Activator (must take one line max).

Remove()

void IFSelect_Activator::Remove ( const char *const command )

static

Select()

bool IFSelect_Activator::Select ( const char *const command, int & number, occ::handle< IFSelect_Activator > & actor )

SetForGroup()

void IFSelect_Activator::SetForGroup	(	const char *const	group,
		const char *const	file = "" )

Group and SetGroup define a "Group of commands" which correspond to an Activator. Default is "XSTEP" Also a file may be attached.
