Detailed Description

A precedence constraint.

The precedence constraint force blocks to be scheduled satisfying a certain partial order.

Constructor & Destructor Documentation

delphos::PrecedenceConstraint::PrecedenceConstraint	(	const string &	name,
		const delphos::Precedence &	prec
	)

Creates a new precedence constraint.

Parameters

name	The name of the precedence constraint.
prec	The precedence.

This method creates a new precedence constraint, which is given by a precedence object (already computed) and has a name within the instance.

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

virtual

Checks if the constraint is satisfied.

Parameters

sch	The schedule to be checked.

Returns true only if the constraint is satisfied.

Reimplemented from delphos::Constraint.

bool delphos::PrecedenceConstraint::Check ( const delphos::FractionalSchedule & sch ) 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).

Reimplemented from delphos::Constraint.

const Precedence & delphos::PrecedenceConstraint::GetPrecedence ( ) const

virtual

Returns the precedence object associated to the constraint.
