int64_t childCount ( ) const Get number of child elements in this VectorNode. Precondition: The destination ImageFile must be open (i.e. destImageFile().isOpen()). Postcondition: No visible state is modified. Returns: Number of child elements in this VectorNode. Exceptions: E57_ERROR_IMAGEFILE_NOT_OPEN E57_ERROR_INTERNAL All objects in undocumented state See also: VectorFunctions.cpp example, VectorNode::get(int64_t), VectorNode::append, StructureNode::childCount
