List of all members.


Public Member Functions
Constraint *	value (QString key) const
	ConstraintGroup ()
bool	hasConstraint (QString className, QString propertyName)
	Returns: true if className has a property called PropertyName with a constraint
virtual QString	toString () const
	Returns: not implemented yet
bool	filter (const ConstrainedDataObject *theObject, QString classname=QString())
	Filter method.
void	addTypeConstraints (const QObject &prototype)
	Intraspects the properties of the prototype and inserts type-based constraints into the constraint map for the prototype's class.
Constraint *	getConstraint (QString className, QString propertyName)
	Return pointer to constraint for a particular className::propertyName.
void	setRegexConstraint (QString className, QString propertyName, QString regularExpression)
	Convenience method which creates/sets a RegexConstraint.
void	setDoubleRangeConstraint (QString className, QString propertyName, double lowval, double highval)
	Convenience method which creates/sets a DoubleRangeConstraint.
void	setConstraint (QString className, QString propertyName, Constraint *constraint)
	Sets a constraint on a particular className::propertyName.
virtual	~ConstraintGroup ()
	Deletes the constraint objects that were added to this structure as well.

Detailed Description

Used to describe multidimensional constraints. First, it is a singleton used by ConstrainedDataObject to impose setProperty() constraints. Second, it is used to describe multidimensional queries.

Member Function Documentation

bool ConstraintGroup::filter	(	const ConstrainedDataObject *	theObject,
		QString	classname = `QString()`
	)

Filter method.

Parameters:

	theObject	- the object with values to check against constraints
	classname	- the name of the class which we wish to constrain the dataobject. If null, then defaults to whatever theObject.objectype() returns.
