Class TX3DExport

Unit

Declaration

type TX3DExport = class(TX3DFileItem)

Description

No description available, ancestor TX3DFileItem description follows

Base class for any item within VRML/X3D file: a node, a field, a route, a prototype etc. We need a common base class for all such things to store PositionInParent.

About ancestry: TX3DFieldOrEvent make use of Assign mechanism and so need to descend from TPersistent. TX3DNode make use of interfaces and so must descend from something like TNonRefCountedInterfacedXxx. These are the only reasons, for now, why this descends from TNonRefCountedInterfacedPersistent.
