Detailed Description

A class which provides the methods for setting PROP values of a replica to value they had the last time the replica was used.

This can be used to provide a "reasonable" value to be displayed until the connection to the source is established and current values are available.

This class must be overridden to provide an implementation for saving (QRemoteObjectAbstractPersistedStore::saveProperties) and restoring (QRemoteObjectAbstractPersistedStore::restoreProperties) PROP values. The derived type can then be set for a node, and any replica acquired from that node will then automatically store PERSISTED properties when the replica destructor is called, and retrieve the values when the replica is instantiated.

QRemoteObjectAbstractPersistedStore::QRemoteObjectAbstractPersistedStore(QObject *parent = nullptr)

Constructs a QRemoteObjectAbstractPersistedStore with the given parent. The default value of parent is nullptr.

[protected] QRemoteObjectAbstractPersistedStore::QRemoteObjectAbstractPersistedStore(QRemoteObjectAbstractPersistedStorePrivate &, QObject *parent)

Default constructs an instance of QRemoteObjectAbstractPersistedStore.

[virtual] QRemoteObjectAbstractPersistedStore::~QRemoteObjectAbstractPersistedStore()

Destroys the instance of QRemoteObjectAbstractPersistedStore. The destructor is virtual.

[pure virtual] QVariantList QRemoteObjectAbstractPersistedStore::restoreProperties(const QString &repName, const QByteArray &repSig)

[pure virtual] void QRemoteObjectAbstractPersistedStore::saveProperties(const QString &repName, const QByteArray &repSig, const QVariantList &values)
