Member Function Documentation

◆ AddChildNode()

◆ addNodeRef()

void X3DNODE::addNodeRef ( X3DNODE aNode)

Add a pointer to a node which references, but does not own, this node.

Such back-pointers are required to ensure that invalidated references are removed when a node is deleted.

Parameters
aNodeis the node holding a reference to this object.

Definition at line 142 of file x3d_base.cpp.

References m_BackPointers, and m_Parent.

Referenced by X3DIFACESET::AddRefNode(), X3DSHAPE::AddRefNode(), and X3DTRANSFORM::AddRefNode().

◆ AddRefNode()

virtual bool X3DNODE::AddRefNode ( X3DNODE aNode)
pure virtual

◆ delNodeRef()

void X3DNODE::delNodeRef ( X3DNODE aNode)

Remove a pointer to a node which references, but does not own, this node.

Parameters
aNodeis the node holding a reference to this object.

References m_BackPointers, and traceVrmlPlugin.

◆ GetError()

std::string X3DNODE::GetError ( void  )

Definition at line 202 of file x3d_base.cpp.

References m_error.

◆ GetName()

wxString X3DNODE::GetName ( void  ) const

Return the name of this object.

Definition at line 196 of file x3d_base.cpp.

References m_Name.

◆ GetNodeType()

◆ GetParent()

X3DNODE * X3DNODE::GetParent ( void  ) const

Return a pointer to the parent node of this object or NULL if the object has no parent (ie.

top level transform).

Definition at line 190 of file x3d_base.cpp.

References m_Parent.

Referenced by X3DIFACESET::AddChildNode(), X3DSHAPE::AddChildNode(), and X3DTRANSFORM::AddChildNode().

◆ Read()

virtual bool X3DNODE::Read ( wxXmlNode *  aNode,
X3DNODE aTopNode,
X3D_DICT aDict 
)
pure virtual

◆ SetParent()

virtual bool X3DNODE::SetParent ( X3DNODE aParent,
bool  doUnlink = true 
)
pure virtual

Set the parent X3DNODE of this object.

Parameters
aParent[in] is the desired parent node.
doUnlinkindicates that the child must be unlinked from the parent
Returns
true if the operation succeeds or false if the given node is not allowed to be a parent to the derived object.

Implemented in X3DAPP, X3DCOORDS, X3DIFACESET, X3DSHAPE, and X3DTRANSFORM.

Referenced by X3DIFACESET::AddChildNode(), X3DSHAPE::AddChildNode(), and X3DTRANSFORM::AddChildNode().

◆ TranslateToSG()

virtual SGNODE * X3DNODE::TranslateToSG ( SGNODE aParent)
pure virtual

Produce a representation of the data using the intermediate scenegraph structures of the kicad_3dsg library.

Parameters
aParentis a pointer to the parent SG node/
Returns
is non-NULL on success.

Implemented in X3DAPP, X3DCOORDS, X3DIFACESET, X3DSHAPE, and X3DTRANSFORM.

Referenced by X3DPARSER::Load(), and X3DSHAPE::TranslateToSG().

◆ unlinkChildNode()

void X3DNODE::unlinkChildNode ( const X3DNODE aNode)
virtual

Remove references to an owned child; it is invoked by the child upon destruction to ensure that the parent has no invalid references.

Parameters
aNodeis the child which is being deleted.

Reimplemented in X3DSHAPE.

◆ unlinkRefNode()

void X3DNODE::unlinkRefNode ( const X3DNODE aNode)
virtual

Remove pointers to a referenced node; it is invoked by the referenced node upon destruction to ensure that the referring node has no invalid references.

Parameters
aNodeis the node which is being deleted.

Reimplemented in X3DSHAPE.
