if the backend node is enabled.
Returns the mode of the backend mode.
Returns the peer id of the backend node.
Enables or disables the backend node by enabled .

void
QBackendNode::
syncFromFrontEnd
(const
Qt3DCore::QNode
*
frontEnd
,
bool
firstTime
)
QBackendNode::syncFromFrontEnd frontEnd firstTime
This is called by the aspect when a frontEnd node needs to synchronize it's changes with the backend (normally due to property changes).
firstTime will be true if the backend node was just created
