	Hidden constructor.

Protected Attributes
Config *	_destination
	The destination configuration.

QHash< ConfigObject , ConfigObject > &	_translation
	Translation table for fixing references.

Detailed Description

Implements a visitor to merge the visited config into a given config.

The destination configuration object is passed to the constructor. This allows to merge several configurations into one.

Member Enumeration Documentation

◆ ItemStrategy

enum ConfigMergeVisitor::ItemStrategy

strong

Possible strategies to merge atomic items.

That is, Channels, Contacts & PositioningSystems, if there are two items with the same name.

Enumerator
Ignore	Ignore the source item.
Override	Override the destination item.
Duplicate	Add a new item with a modified name.

◆ SetStrategy

enum ConfigMergeVisitor::SetStrategy

strong

Possible strategies to merge sets of references.

That is, GroupLists, Zones & ScanLists, if tehre are two sets with the same name.

Enumerator
Ignore	Ignore the source set.
Override	Override the destination item.
Duplicate	Add a new set with a modified name.
Merge	Merge sets.

Constructor & Destructor Documentation

◆ ConfigMergeVisitor()

ConfigMergeVisitor::ConfigMergeVisitor	(	Config *	destination,
		QHash< ConfigObject , ConfigObject > &	translation,
		ItemStrategy	itemStrategy = `ItemStrategy::Ignore`,
		SetStrategy	setStrategy = `SetStrategy::Ignore`
	)

Constructor of the merge visitor.

Parameters

destination	Specifies the destination configuration, the additional configurations are merged into.
itemStrategy	Specifies the item merge strategy.
setStrategy	Specifies the set merge strategy.

Member Function Documentation

◆ addObject()

bool ConfigMergeVisitor::addObject	(	AbstractConfigObjectList *	list,
		ConfigObject *	present,
		ConfigObject *	merging,
		const ErrorStack &	err = `ErrorStack()`
	)

protected

Adds a copy of the merging object to the given list, containing the colliding present object.

Also updates the translation table to bend references to the merging object to that copy.

◆ mergeList()

bool ConfigMergeVisitor::mergeList	(	ConfigObjectRefList *	present,
		ConfigObjectRefList *	merging,
		const ErrorStack &	err = `ErrorStack()`
	)

protected

Merges two reference lists.

That is, merging gets merged into the present list.

◆ processItem()

bool ConfigMergeVisitor::processItem	(	ConfigItem *	item,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Traverses the specified config item.

This method calls processProperty on all properties of the item.

Reimplemented from Visitor.

◆ replaceObject()

bool ConfigMergeVisitor::replaceObject	(	AbstractConfigObjectList *	list,
		ConfigObject *	present,
		ConfigObject *	merging,
		const ErrorStack &	err = `ErrorStack()`
	)

protected

Replaces the present object in the given list by a copy of merging object.

Also fixes the translation table to bend references to both the removed present object as well as the merging object.
