Detailed Description

Base visitor class for the config tree.

This class can be used to implement a convenient tree taversal for the entry configuration.

Member Function Documentation

◆ process()

bool Visitor::process	(	Config *	config,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Traverses the properties of the configuration recursively.

Returns: true on success. Error information can be found in the error stack, if passed.

◆ processBool()

bool Visitor::processBool	(	ConfigItem *	item,
		const QMetaProperty &	prop,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Handles a boolean typed property.

Parameters

item	Specifies the config item holding this property.
prop	Specifies the property.
err	Specifies the error stack to pass on.

◆ processDouble()

bool Visitor::processDouble	(	ConfigItem *	item,
		const QMetaProperty &	prop,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Handles a double precision float typed property.

Parameters

item	Specifies the config item holding this property.
prop	Specifies the property.
err	Specifies the error stack to pass on.

◆ processEnum()

bool Visitor::processEnum	(	ConfigItem *	item,
		const QMetaProperty &	prop,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Handles an enum typed property.

Parameters

item	Specifies the config item holding this property.
prop	Specifies the property.
err	Specifies the error stack to pass on.

◆ processInt()

bool Visitor::processInt	(	ConfigItem *	item,
		const QMetaProperty &	prop,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Handles an integer typed property.

Parameters

item	Specifies the config item holding this property.
prop	Specifies the property.
err	Specifies the error stack to pass on.

◆ processItem()

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

virtual

Traverses the specified config item.

This method calls processProperty on all properties of the item.

Reimplemented in ConfigLabelingVisitor.

◆ processList()

bool Visitor::processList	(	AbstractConfigObjectList *	list,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Traverses the list of objects or references.

If list is a list of ConfigItem, the visitor will traverse those by calling processItem on every of these element. If it is a list of ConfigObjectRef references, the visitor stop here and simply return true. By default, the visitor does not follow references.

◆ processProperty()

bool Visitor::processProperty	(	ConfigItem *	item,
		const QMetaProperty &	prop,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Processes the specified property of the item.

This method dispatches to the type-specific methods like processEnum, processBool, processInt, processUInt, processDouble, processString, processItem, processReference, processList, and processUnknownType, depending on the type of the property. Do not override this method unless you need to handle all properties differently.

◆ processReference()

bool Visitor::processReference	(	ConfigObjectReference *	ref,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Handles references to config objects.

By default, the method will simply return true. The visitor does not follow references.

◆ processString()

bool Visitor::processString	(	ConfigItem *	item,
		const QMetaProperty &	prop,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Handles a string typed property.

Parameters

item	Specifies the config item holding this property.
prop	Specifies the property.
err	Specifies the error stack to pass on.

◆ processUInt()

bool Visitor::processUInt	(	ConfigItem *	item,
		const QMetaProperty &	prop,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Handles an unsigned integer typed property.

Parameters

item	Specifies the config item holding this property.
prop	Specifies the property.
err	Specifies the error stack to pass on.

◆ processUnknownType()

bool Visitor::processUnknownType	(	ConfigItem *	item,
		const QMetaProperty &	prop,
		const ErrorStack &	err = `ErrorStack()`
	)

virtual

Handles a property of unknown type.

Returns always false.

Parameters

item	Specifies the config item holding this property.
prop	Specifies the property.
err	Specifies the error stack to pass on.
