详细描述

The Node type provides an entry point to a Qt Remote Objects network. A network can be as simple as two nodes, or an arbitrarily complex set of processes and devices.

A Node does not have a url that other nodes can connect to, and thus is able to acquire replicas only. It is not able to share source objects.

特性文档编制

heartbeatInterval : int

心跳间隔 (以毫秒为单位)。

The heartbeat (only helpful for socket connections) will periodically send a message to connected nodes to detect whether the connection was disrupted. Qt Remote Objects will try to reconnect automatically if it detects a dropped connection. This function can help with that detection since the client will only detect that the server is unavailable when it tries to send data.

值 0 (默认) 将禁用心跳。

persistedStore : QRemoteObjectAbstractPersistedStore

允许设置 QRemoteObjectAbstractPersistedStore 实例为节点。

允许复本 PROP members with the PERSISTED trait to save their current value when the replica is deleted and restore a stored value the next time the replica is started.

要求 QRemoteObjectAbstractPersistedStore class implementation to control where and how persistence is handled. A default QSettings -based implementation is provided by SettingsStore .

registryUrl : url

The address of the 注册 used by this node.

这是空 QUrl 若没有在使用中的注册。
