Member Function Documentation

◆ affectsState()

virtual SbBool SoNode::affectsState ( ) const

virtual

Returns TRUE if a node has an effect on the state during traversal.

The default method returns TRUE. Node classes (such as SoSeparator) that isolate their effects from the rest of the graph override this method to return FALSE.

Reimplemented in SoInteractionKit, SoNodeKitListPart, SoSceneKit, SoSeparatorKit, SoArray, SoComputeShaderScheduler, SoInteractiveSwitch, SoMultipleCopy, SoMultiSwitch, SoShape, SoViewingCube, PoBase, MoMeshBaseRepresentation, and SoOrthoSlice.

◆ copy()

virtual SoNode * SoNode::copy ( SbBool copyConnections = FALSE ) const

virtual

Creates and returns an exact copy of the node.

If the node is a group, it copies the children as well. If copyConnections is TRUE (it is FALSE by default), any connections to (but not from) fields of the node are copied, as well. Note that multiple references to a node under the node to be copied will result in multiple references to the copy of that node. To be copyable, a custom node must define a default contructor. Note that OIV require that every custom node must define a default contructor.

Please also note that instance data other than Inventor fields and public children will not be copied by this method. If extra data needs to be copied as well, this method will have to be manually overridden.

Reimplemented in SoClipPlaneManip, and PoBase.

◆ getByName() [1/2]

static SoNode * SoNode::getByName ( const SbName & name )

static

A node's name can be set using SoBase::setName().

This method allows nodes to be looked up by name. It returns the last node given the specified name.

◆ getByName() [2/2]

static int SoNode::getByName	(	const SbName &	name,
		SoNodeList &	list
	)

static

A node's name can be set using SoBase::setName().

This method allows nodes to be looked up by net name. It returns the number of nodes with the given net name, and adds to list those nodes.

◆ getClassTypeId()

static SoType SoNode::getClassTypeId ( )

static

Returns the type identifier for this class.

◆ getTypeId()

virtual SoType SoNode::getTypeId ( ) const

virtual

Returns the type identifier for this specific instance.

Implements SoTypedObject.

◆ isOverride()

SbBool SoNode::isOverride ( ) const

inlinevirtual

Returns the state of the override flag.

Reimplemented in SoBaseColor, SoColorIndex, SoComplexity, SoDepthBuffer, SoDrawStyle, SoEnvironment, SoFont, SoFullSceneAntialiasing, SoLightModel, SoMaterial, SoMaterialBinding, SoPackedColor, SoPattern, SoPickStyle, SoPolygonOffset, SoShapeHints, SoTextProperty, SoTexture, and SoVertexProperty.

Definition at line 500 of file SoNode.h.

◆ setOverride()

void SoNode::setOverride ( const SbBool state )

inlinevirtual

Turns the override flag on or off.

The following property nodes are affected by the override flag: SoBaseColor, SoColorIndex, SoComplexity, SoDepthBuffer, SoDrawStyle, SoEnvironment, SoFont, SoFullSceneAntialiasing, SoLightModel, SoMaterial, SoMaterialBinding, SoPackedColor, SoPattern, SoPickStyle, SoPolygonOffset, SoShapeHints, SoVertexProperty, SoTextProperty.

Every node has an override flag associated with it. The override flag is a powerful mechanism typically used (sparingly) near the top of a scene graph. When this flag is set, any nodes of the same type encountered later in the graph are ignored even if they also have their own override flag set. For example, you might insert a line-style SoDrawStyle node at the top of a graph to ensure that the whole scene is drawn as wireframe objects, regardless of drawing styles specified lower in the scene graph. Use the setOverride() method to set and reset the override flag. The isOverride() method returns the state of the override flag.

Normally, the override flag is not used within a scene graph for modeling. Use it in applications where you need to specify a temporary change to the whole graph.

Note: The override flag is not written to a file.

Setting the override flag on a node whose field values are not inherited (for example on a sphere with a radius of 7) has no effect on other nodes in the graph of that type.

Reimplemented in SoBaseColor, SoColorIndex, SoComplexity, SoDepthBuffer, SoDrawStyle, SoEnvironment, SoFont, SoFullSceneAntialiasing, SoLightModel, SoMaterial, SoMaterialBinding, SoPackedColor, SoPattern, SoPickStyle, SoPolygonOffset, SoShapeHints, SoTextProperty, SoTexture, and SoVertexProperty.

Definition at line 492 of file SoNode.h.

◆ touch()

virtual void SoNode::touch ( )

virtual

Marks an instance as modified, simulating a change to it.

This will notify auditors (parent nodes, connected engines, and so on) of a change to this object and cause attached sensors to be triggered.

Reimplemented from SoBase.
