Constructor & Destructor Documentation

VrmlData_Group::VrmlData_Group

(

const Standard_Boolean

isTransform = Standard_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::VrmlData_Group	(	const VrmlData_Scene &	theScene,
		const char *	theName,
		const Standard_Boolean	isTransform = Standard_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

Handle< VrmlData_Node >& VrmlData_Group::AddNode

(

const Handle< VrmlData_Node > &

theNode

)

[inline]

Add one node to the Group.

const Bnd_B3f& VrmlData_Group::Box

(

)

const [inline]

Query the bounding box.

virtual Handle< VrmlData_Node > VrmlData_Group::Clone

(

const Handle< VrmlData_Node > &

theOther

)

const [virtual]

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.

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.

const gp_Trsf& VrmlData_Group::GetTransform

(

)

const [inline]

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

Standard_Boolean VrmlData_Group::IsTransform

(

)

const [inline]

Query if the node is Transform type.

Iterator VrmlData_Group::NodeIterator

(

)

const [inline]

Create iterator on nodes belonging to the Group.

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.

virtual VrmlData_ErrorStatus VrmlData_Group::Read

(

VrmlData_InBuffer &

theBuffer

)

[virtual]

Fill the Node internal data from the given input stream.

Implements VrmlData_Node.

Standard_Boolean VrmlData_Group::RemoveNode

(

const Handle< VrmlData_Node > &

theNode

)

Remove one node from the Group.

Returns:

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

void VrmlData_Group::SetBox

(

const Bnd_B3f &

theBox

)

[inline]

Set the bounding box.

Standard_Boolean VrmlData_Group::SetTransform

(

const gp_Trsf &

theTrsf

)

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

void VrmlData_Group::Shape	(	TopoDS_Shape &	theShape,
		VrmlData_DataMapOfShapeAppearance *	pMapApp
	)

Get the shape representing the group geometry.

virtual VrmlData_ErrorStatus VrmlData_Group::Write

(

const char *

thePrefix

)

const [virtual]

Write the Node to output stream.

Reimplemented from VrmlData_Node.
