Detailed Description

Defines the base class for all constraints.

A constraint is a condition that must be fulfilled by a schedule 'solving' a scheduling instance.

This class provides dummy implementations of the base methods, which are expected to be defined by sub-classes.

The class also provides utility functions to create XML representations of the constraints.

Constructor & Destructor Documentation

delphos::Constraint::Constraint

(

const string &

name

)

Creates a constraint with given name.

Parameters

name	A name describing the constraint.

Creates a new constraint with given name.

delphos::Constraint::~Constraint ( )

virtual

Destructor.

Destructor.

Member Function Documentation

bool delphos::Constraint::Check ( const delphos::Schedule &  sch ) const

virtual

Checks if the given schedule satisfies the constraint.

Parameters

sch	The schedule to be checked.

This method checks if the given schedule satisfies the constraint (returning true) or not (return false).

For this class, a dummy version that always return false.

Reimplemented in delphos::GeometricConstraint, delphos::BlockSelectionPrecedenceConstraint, delphos::PrecedenceConstraint, delphos::AttributeAvgConstraint, delphos::AttributeSumConstraint, delphos::MinExtractPeriodConstraint, delphos::DoNotSendToConstraint, delphos::DoNotMineBeforeConstraint, and delphos::ForceMiningByConstraint.

bool delphos::Constraint::Check ( const delphos::FractionalSchedule &  fsch ) const

virtual

Checks if the given fractional schedule satisfies the constraint.

Parameters

fsch	The fractional schedule to be checked.

This method checks if the given schedule satisfies the constraint (returning true) or not (return false).

For this class, a dummy version that always return false.

Reimplemented in delphos::GeometricConstraint, delphos::BlockSelectionPrecedenceConstraint, delphos::PrecedenceConstraint, delphos::AttributeAvgConstraint, delphos::AttributeSumConstraint, delphos::DoNotSendToConstraint, delphos::DoNotMineBeforeConstraint, and delphos::ForceMiningByConstraint.

string delphos::Constraint::ToXML ( const unsigned int  identation_level = 0 ) const

virtual

A XML string describing the constraint.

Parameters

identation_level

Identation level of the XML produced.

Constructs a XML string describing the constraint's name and potential attributes.
