详细描述

The QRemoteObjectHost class provides an entry point to a QtRemoteObjects 网络。网络可以简单到 2 节点，或任意复杂的一组进程和设备。

QRemoteObjectHosts 拥有如 QRemoteObjectNodes 的相同能力，但它们还可以连接到网络源对象并共享网络源对象。

节点可以相互直接连接使用 connectToNode ，或者它们可以使用 QRemoteObjectRegistry 以简化连接。

QRemoteObjectRegistry is a special replica available to every node that connects to the uegistry Url. It knows how to connect to every QRemoteObjectSource object on the network.

特性文档编制

hostUrl : QUrl

This property holds the host address for the node.

This is the address where source objects remoted by this node will reside.

访问函数：

virtual QUrl	hostUrl () const override
virtual bool	setHostUrl (const QUrl & hostAddress , QRemoteObjectHostBase::AllowedSchemas allowedSchemas = BuiltInSchemasOnly) override

通知程序信号：

void	hostUrlChanged ()

成员函数文档编制

QRemoteObjectHost:: QRemoteObjectHost (const QUrl & address , QObject * parent )

Constructs a new QRemoteObjectHost Node (i.e., a Node that supports exposing 源 对象在 QtRO 网络) 采用 URL address 和给定 parent 。提供此重载是为方便指定 QObject 父级不用提供注册地址。

另请参阅 setHostUrl () 和 setRegistryUrl ().

QRemoteObjectHost:: QRemoteObjectHost (const QUrl & address , const QUrl & registryAddress = QUrl(), QRemoteObjectHostBase::AllowedSchemas allowedSchemas = BuiltInSchemasOnly, QObject * parent = nullptr)

Constructs a new QRemoteObjectHost Node (i.e., a Node that supports exposing 源 对象在 QtRO 网络) 采用地址 address 。若设置， registryAddress 将用于连接到 QRemoteObjectRegistry at the provided address. The allowedSchemas parameter is only needed (and should be set to AllowExternalRegistration ) if the schema of the url should be used as an External Schema by the registry.

另请参阅 setHostUrl () 和 setRegistryUrl ().

QRemoteObjectHost:: QRemoteObjectHost ( QObject * parent = nullptr)

Constructs a new QRemoteObjectHost Node (i.e., a Node that supports exposing 源 对象在 QtRO 网络) 采用给定 parent . This constructor is meant specific to support QML in the future as it will not be available to connect to until setHostUrl 被调用。

另请参阅 setHostUrl () 和 setRegistryUrl ().

[override virtual] QUrl QRemoteObjectHost:: hostUrl () const

返回主机地址为 QRemoteObjectNode 作为 QUrl . If the Node is not a Host node, returns an empty QUrl .

注意： Getter function for property hostUrl.

另请参阅 setHostUrl ().

[override virtual] bool QRemoteObjectHost:: setHostUrl (const QUrl & hostAddress , QRemoteObjectHostBase::AllowedSchemas allowedSchemas = BuiltInSchemasOnly)

设置 hostAddress 为主机 QRemoteObjectNode .

返回 true 若有设置 Host (主机) 地址，否则 false .

allowedSchemas parameter is only needed (and should be set to AllowExternalRegistration ) if the schema of the url should be used as an External Schema by the registry.

注意： Setter 函数对于特性 hostUrl .
