	Standard_Transient ()
	Empty constructor.

	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.

Detailed Description

Implementation of node "Group"

Member Typedef Documentation

◆ Iterator

typedef NCollection_List<occ::handle<VrmlData_Node>>::Iterator VrmlData_Group::Iterator

Constructor & Destructor Documentation

◆ VrmlData_Group() [1/2]

VrmlData_Group::VrmlData_Group ( const bool isTransform = false )

inline

Empty constructor.

Parameters

isTransform	True if the group of type Transform is defined
theAlloc	Allocator used for the list of children

◆ VrmlData_Group() [2/2]

VrmlData_Group::VrmlData_Group	(	const VrmlData_Scene &	theScene,
		const char *	theName,
		const bool	isTransform = false )

Constructor.

Parameters

theName	Name of the Group node
isTransform	True if the group of type Transform is defined
theAlloc	Allocator used for the list of children

Member Function Documentation

◆ AddNode()

occ::handle< VrmlData_Node > & VrmlData_Group::AddNode ( const occ::handle< VrmlData_Node > & theNode )

inline

Add one node to the Group.

◆ Box()

const Bnd_B3f & VrmlData_Group::Box ( ) const

inline

Query the bounding box.

◆ Clone()

occ::handle< VrmlData_Node > VrmlData_Group::Clone ( const occ::handle< VrmlData_Node > & theOther ) const

overridevirtual

Create a copy of this node. If the parameter is null, a new copied node is created. Otherwise new node is not created, but rather the given one is modified.

Reimplemented from VrmlData_Node.

◆ FindNode()

occ::handle< VrmlData_Node > VrmlData_Group::FindNode	(	const char *	theName,
		gp_Trsf &	theLocation ) const

Find a node by its name, inside this Group

Parameters

theName	Name of the node to search for.
theLocation	Location of the found node with respect to this Group.

◆ GetTransform()

const gp_Trsf & VrmlData_Group::GetTransform ( ) const

inline

Query the transform value. For group without transformation this always returns Identity

◆ IsTransform()

bool VrmlData_Group::IsTransform ( ) const

inline

Query if the node is Transform type.

◆ NodeIterator()

Iterator VrmlData_Group::NodeIterator ( ) const

inline

Create iterator on nodes belonging to the Group.

◆ openFile()

VrmlData_ErrorStatus VrmlData_Group::openFile	(	Standard_IStream &	theStream,
		const TCollection_AsciiString &	theFilename )

protected

Try to open a file by the given filename, using the search directories list myVrmlDir of the Scene.

◆ Read()

VrmlData_ErrorStatus VrmlData_Group::Read ( VrmlData_InBuffer & theBuffer )

overridevirtual

Fill the Node internal data from the given input stream.

Implements VrmlData_Node.

◆ RemoveNode()

bool VrmlData_Group::RemoveNode ( const occ::handle< VrmlData_Node > & theNode )

Remove one node from the Group.

Returns: True if the node was located and removed, False if none removed.

◆ SetBox()

void VrmlData_Group::SetBox ( const Bnd_B3f & theBox )

inline

Set the bounding box.

◆ SetTransform()

bool VrmlData_Group::SetTransform ( const gp_Trsf & theTrsf )

Set the transformation. Returns True if the group is Transform type, otherwise do nothing and return False.

◆ Shape()

void VrmlData_Group::Shape	(	TopoDS_Shape &	theShape,
		NCollection_DataMap< occ::handle< TopoDS_TShape >, occ::handle< VrmlData_Appearance > > *	pMapApp )

Get the shape representing the group geometry.

◆ Write()

VrmlData_ErrorStatus VrmlData_Group::Write ( const char * thePrefix ) const

overridevirtual

Write the Node to output stream.

Reimplemented from VrmlData_Node.
