Method Summary

BigDecimal	getLowerLimit()
BigDecimal	getUpperLimit()
boolean	isConstraint() The Constraint has a lower or an upper limit (possibly both).
boolean	isEqualityConstraint() The Constraint has both a lower limit and an upper limit, and they are equal.
boolean	isLowerConstraint() The Constraint has a lower limit, and the upper limit (if it exists) is different.
boolean	isUpperConstraint() The Constraint has an upper limit, and the lower limit (if it exists) is different.
void	setLowerLimit(BigDecimal aValue)
void	setUpperLimit(BigDecimal aValue)
boolean	validate() The lower limit (if it exists) must not be greater than the upper limit (if it exists).
