Member Enumeration Documentation

◆ Scope

enum BpsSettings::Scope

Scope under which the settings are located.

The term "local machine" refers to the user workstation in fat client environments, however in terminal server environments it is the terminal server (citrix for example).

Enumerator
NoScope	No valid scope. Used for example as result by groupScope().
LocalUserScope	Settings of the current operating system user on the local machine. On windows this is in the registry under HKCU/Software/IBK Software AG/BPS2
LocalInstallScope	Settings of the software installation on the locale machine. On windows this is the file bps.conf in the same directory as the executed program. For example when the currently executed program is located in C:\Programs\IBK Software AG\BPS2\bin, the settings are in file C:\Programs\IBK Software AG\BPS2\bin\bps.conf
LocalSystemScope	Settings valid for all users on the local machine. On windows this is in the registry under HKLM/Software/IBK Software AG/BPS2
CentralUserScope	Central settings for the current bps user. The settings are located in the database table t_usersettings.
CentralSystemScope	Central settings for all bps users. The settings are located in the database table t_settings.
LocalScopes	All local scopes. Use only for parameters of type Scopes.
CentralScopes	All central scopes. Use only for parameters of type Scopes.
AllScopes	All scopes. Use only for parameters of type Scopes.

Constructor & Destructor Documentation

◆ BpsSettings() [1/2]

BpsSettings::BpsSettings	(	BpsDatastore *	aDatastore,
		Scope	aScope = `BpsSettings::LocalUserScope`,
		QObject *	aParent = `nullptr`
	)

Constructor for the BpsSettings objects.

Use this constructor when directly accessing central settings, or the settings chain shall be searched up to CentralSystemScope by findValue().

Parameters

aDatastore	The opened database connection.
aScope	The scope to operate on.
aParent	Pointer to parent object.

◆ BpsSettings() [2/2]

BpsSettings::BpsSettings	(	Scope	aScope = `BpsSettings::LocalUserScope`,
		QObject *	aParent = `nullptr`
	)

Constructor for the BpsSettings objects.

Use this constructor when accessing local setting only.

Parameters

aScope	The scope to operate on.
aParent	Pointer to parent object.

Member Function Documentation

◆ allGroups()

QStringList BpsSettings::allGroups ( Scopes aSearchedScopes = (Scopes) AllScopes ) const

Find all groups within the currently opened path.

Search begins at the current scope and goes up to CentralSystemScope. When using the constructor without datastore, the search stops at LocalSystemScope instead of CentralSystemScope. Group names found at multiple scopes are merged into one entry.

Parameters

aSearchedScopes Mask of scopes that shall be included in the search.

Returns: A list of the found group names.

◆ allKeys()

QStringList BpsSettings::allKeys ( Scopes aSearchedScopes = (Scopes) AllScopes ) const

Find all keys within the currently opened path.

Search begins at the current scope and goes up to CentralSystemScope. When using the constructor without datastore, the search stops at LocalSystemScope instead of CentralSystemScope. Key names found at multiple scopes are merged into one entry.

Parameters

aSearchedScopes Mask of scopes that shall be included in the search.

Returns: A list of the found key names.

◆ closeAll()

void BpsSettings::closeAll ( )

Close all currently opened paths.

The current location is set back to the root.

◆ findValue()

QVariant BpsSettings::findValue	(	const QString &	aKey,
		const QVariant &	aDefValue = `QVariant()`,
		Scopes	aSearchedScopes = `(Scopes) AllScopes`
	)		const

Find a value within the currently opened path.

If the value is not found in the current scope, the scope chain is searched up to CentralSystemScope for such a value. When still not found, the default will be returned. When using the constructor without datastore, the search stops at LocalSystemScope instead of CentralSystemScope.

Parameters

aKey	The key of the value.
aDefValue	Default value to return in case the key does not exist.
aSearchedScopes	Mask of scopes that shall be included in the search.

Returns: The keys value, or the provided default value in case the key does not exist.

◆ groupExists()

bool BpsSettings::groupExists ( const QString & aGroup ) const

Check if the group exists in the current scope.

The group name compare is done case-insensitive, so the method is equivalent to groups().contains(aGroup, Qt::CaseInsensitive).

Parameters

aGroup The group to check.

Returns: True if the group exists, false if not.

◆ groups()

QStringList BpsSettings::groups ( ) const

Query a list of all existing groups within the currently opened path.

Returns: All child groups at the currently opened path.

◆ groupScope()

Scope BpsSettings::groupScope	(	const QString &	aName,
		Scopes	aSearchedScopes = `(Scopes) AllScopes`
	)		const

Find the first scope of a group within the currently opened path.

Search begins at the current scope and goes up to CentralSystemScope. When using the constructor without datastore, the search stops at LocalSystemScope instead of CentralSystemScope.

Parameters

aSearchedScopes	Mask of scopes that shall be included in the search.
aName	The name of the group. Name compare is case-insensitive.

Returns: Scope of the first group found, or NoScope if no such group found.

◆ keyExists()

bool BpsSettings::keyExists ( const QString & aKey ) const

Check if the key exists in the current scope.

The key name compare is done case-insensitive, so the method is equivalent to keys().contains(aKey, Qt::CaseInsensitive).

Parameters

aKey	The key to check.

Returns: True if the key exists, false if not.

◆ keys()

QStringList BpsSettings::keys ( ) const

Query a list of all existing keys in the currently opened group.

Returns: All keys within the currently opened path.

◆ open()

void BpsSettings::open ( const QString & aPath )

Open a new path.

Parameters

aPath The path to open, relative to the currently opened path.

◆ removeGroup()

void BpsSettings::removeGroup ( const QString & aName )

Remove a group from the currently opened path.

In case no group of the given name exists, nothing happens.

Parameters

aName The name of the group. Name compare is case-insensitive.

◆ removeKey()

void BpsSettings::removeKey ( const QString & aKey )

Remove a key.

Parameters

aKey	Name of the key to remove. Key names are case insensitive.

◆ root()

QString BpsSettings::root ( ) const

Get the current root.

The root is prepended to all paths. Initially the root is empty.

Returns: The current root.

◆ scope()

Scope BpsSettings::scope ( ) const

Returns: The current scope.

◆ setRoot()

void BpsSettings::setRoot ( const QString & aRoot )

Set a new root.

The root is prepended to all paths. Initially the root is empty.

Parameters

aRoot The new root to set.

◆ setScope()

void BpsSettings::setScope ( Scope aScope )

Change the current scope.

Parameters

aScope The new scope to be set.

◆ setValue()

void BpsSettings::setValue	(	const QString &	aKey,
		const QVariant &	aValue
	)

Set a value within the currently opened path.

Parameters

aKey	The key for the value.
aValue	The value to save under this key.

◆ setValueMap()

void BpsSettings::setValueMap ( const QVariantMap & aMap )

Removes any previously existing keys from the currently opened path and scope, and adds the values in the given map instead.

Parameters

aMap	The map of key/value pairs to set.

◆ value()

QVariant BpsSettings::value	(	const QString &	aKey,
		const QVariant &	aDefValue = `QVariant()`
	)		const

Get a value within the currently opened path.

Parameters

aKey	The key of the value.
aDefValue	Default value to return in case the key does not exist.

Returns: The keys value, or the provided default value in case the key does not exist.

◆ valueMap()

QVariantMap BpsSettings::valueMap ( Scopes aSearchedScopes = (Scopes) AllScopes ) const

Find all keys and values within the currently opened path.

The scope chain is searched up to CentralSystemScope for values. When using the constructor without datastore, the search stops at LocalSystemScope instead of CentralSystemScope. This map contains basically all tha key/value pairs addressed by allKeys().

Parameters

aSearchedScopes Mask of scopes that shall be included in the search.

Returns: A map of all key/value pairs in the currently opened path.
