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.
