procedure Bind(const Node: TX3DNode; const NodeFinished: boolean); overload; |
|
Associate given node with it's own name. If not NodeFinished, then we understand that we're parsing / saving the node's contents now. If NodeFinished, then we know the node contents are fully parsed / saved now. This information helps us to detect cycles in X3D DEF/USE graph. For now, we just disallow such cycles. Still, we allow ROUTEs from inside the node, so calling with NodeFinished = false is still useful for parsing. | |

function Bound(const Name: string; out NodeFinished: boolean): TX3DNode; overload; |
|
Find node bound to given name. | |
|
function NodeDuringReading(const Node: TX3DNode): Boolean; |
|
Node is during reading, judging from Bind calls with NodeFinished= | |
|
function Bound(const Node: TX3DNode): boolean; overload; |
|
Check is Node bound in the current namespace. Doesn't check is Node bound to it's name (Node.Name) or something else. So this assumes that node can only be bound (if at all) only to it's own name, which is true during parsing (when nothing can change in the middle of parsing). | |
