Detailed Description
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.
Property Documentation
heartbeatInterval : int
Heartbeat interval in ms.
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.
A value of 0
(the default) will disable the heartbeat.
persistedStore : QRemoteObjectAbstractPersistedStore
Allows setting a QRemoteObjectAbstractPersistedStore instance for the node.
Allows replica 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.
Requires a 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 Registry used by this node.
This is an empty QUrl if there is no registry in use.
