Package org.opentrafficsim.base.parameters.constraint

Class SingleBound<T extends java.lang.Number>

java.lang.Object

org.opentrafficsim.base.parameters.constraint.SingleBound<T>

Type Parameters:

T - value type

All Implemented Interfaces:

Constraint<T>

Direct Known Subclasses:

DualBound

public class SingleBound<T extends java.lang.Number>
extends java.lang.Object
implements Constraint<T>

Continuous constraints with a single bound. To allow both Double and AbstractDoubleScalar<?, ?> constraints, the generic type is restricted to Number. However, that also allows other subclasses of Number, e.g. Integer. Due to rounding and value limits from the type (e.g. Integer.MAX_VALEU), bounds may not function correctly after a call to Number.doubleValue(). To restrict the usage, the constructor is private and static factory methods for Double and AbstractDoubleScalar<?, ?> are supplied.
