  +--org.fopps.model.ConstraintChecker

Direct Known Subclasses:

ConfigurationConstraintChecker, FeatureConstraintChecker

public abstract class ConstraintChecker

extends java.lang.Object

ConstraintChecker is the base class for all tests regarding feature constraint integrity. Subclasses must override checkConstraints to perform their own method of constraint checking.

checkConstraints(AbstractItem), ConstraintViolation

ConstraintChecker()
Creates a new constraint checker

Method Summary

void	addMessage(java.lang.String pMessage, int pSeverity) Adds a violation message
void	addMessage(java.lang.String pMessage, int pSeverity, AbstractItem pFirst, AbstractItem pSecond) Adds a violation message
abstract boolean	checkConstraints(AbstractItem pRoot) Checks the consistency of constraints return false, if one or more errors occured, otherwise true
void	clearMessages() Drops all violation messages
java.util.Collection	getMessages() Returns the list of constraint violations
boolean	hasMessages() Returns true, if constraint violations were detected
