Constructor Detail

Interval

public Interval(Interval.Closure closure,
                T leftMargin,
                T rightMargin)

Creates a new interval

Parameters:

closure - the closure of the interval

leftMargin - the lower bound of the interval

rightMargin - the upper bound of the interval

Method Detail

openClosed

public static <T extends Number & Comparable<? super T>> Interval<T> openClosed(T left,
                                                                                T right)

Creates an interval (left,right]

Parameters:

left - the left

right - the right

Returns:

an internal (left,right]

openOpen

public static <T extends Number & Comparable<? super T>> Interval<T> openOpen(T left,
                                                                              T right)

Creates an interval (left,right)

Parameters:

left - the left

right - the right

Returns:

an internal (left,right)

closedOpen

public static <T extends Number & Comparable<? super T>> Interval<T> closedOpen(T left,

Creates an interval [left,right)

Parameters:

left - the left

right - the right
