Detailed Description

The PersistenceSettingRetention class retention of subscription data that is used within mutilverse for setup data.

We do not use any database, but rather buit in Qt settings for retaining data for setup data This class is thread safe so all subscribers in different plugin can use it

Constructor & Destructor Documentation

PersistenceSettingRetention()

PersistenceSettingRetention::PersistenceSettingRetention ( QString  project, QString  path = "", QObject *  parent = 0  )

explicit

PersistenceSettingRetention.

Parameters

project	Project name
path	path for storing retention files
parent	QObject parent

make a file for ini stuff... but put it in the home dir is nothing was passed

Member Function Documentation

ReadValues() [1/2]

bool PersistenceSettingRetention::ReadValues ( QString  name, VremVArray &  i1  )

virtual

reads the last saved values of a subscriber

put this out of the locker scope to make it faster

never use the reg if windows, this would be nuts. always use a inifile

cast the QVariant to a list

if there was never a list, return false. IE if never stored before make it return false

Reimplemented from Retain.

ReadValues() [2/2]

bool PersistenceSettingRetention::ReadValues ( Subscription *  subscriber )

virtual

reads the last saved values of a subscriber

lock the QSetting files

make a key out of the name, use a mangle name type so it could work later with MySQL or SQLIte

put this out of the locker scope to make it faster

never use the reg if windows, this would be nuts. always use a inifile

cast the QVariant to a list

if there was never a list, return false. IE if never stored before make it return false

no, there is a values stored

Reimplemented from Retain.

WriteValues() [1/2]

void PersistenceSettingRetention::WriteValues ( QString  name, const VremVArray  i1  )

virtual

make a key out of the name, use a mangle name type so it could work later with MySQL or SQLIte

convert them to a QVariantList

lock the file

write the QVariantList as a QVariant

Reimplemented from Retain.

WriteValues() [2/2]

void PersistenceSettingRetention::WriteValues ( Subscription *  subscriber )

virtual

method for writing

lock the file

make a key out of the name, use a mangle name type so it could work later with MySQL or SQLIte

get all the values from the subsriber

convert them to a QVariantList

write the QVariantList as a QVariant

Reimplemented from Retain.
