bool QBackendNode:: isEnabled () const

返回 true if the backend node is enabled.

Qt3DCore::QBackendNode::Mode QBackendNode:: mode () const

Returns the mode of the backend mode.

[protected] void QBackendNode:: notifyObservers (const Qt3DCore::QSceneChangePtr & e )

Notifies observers of scene change e .

Qt3DCore::QNodeId QBackendNode:: peerId () const

Returns the peer id of the backend node.

[virtual protected] void QBackendNode:: sceneChangeEvent (const Qt3DCore::QSceneChangePtr & e )

TODO e

[protected] QNodeCommand::CommandId QBackendNode:: sendCommand (const QString & name , const QVariant & data , QNodeCommand::CommandId replyTo = QNodeCommand::CommandId())

Send the command named name with contents data , and specify replyTo as the command id to which the reply needs to be sent.

[protected] void QBackendNode:: sendReply (const Qt3DCore::QNodeCommandPtr & 命令 )

Send the reply to 命令 .

void QBackendNode:: setEnabled ( bool enabled )

Enables or disables the backend node by enabled .
