Constructor Detail

OpenInterval

public OpenInterval()

Default constructor - creates the empty interval.

OpenInterval

public OpenInterval(double min,
                    double max)
             throws MathException

Initializing constructor - create a new open interval with specified endpoints.

Parameters:

min - left endpoint

max - right endpoint

Throws:

MathException - max is smaller than min

OpenInterval

public OpenInterval(Interval I)
             throws MathException

Copy constructor - create a new open interval initialized to the argument.

Parameters:

I - interval to copy

Throws:

MathException - malformed interval object

Method Detail

membership

public boolean membership(double x)

Is point a member of the open interval

Overrides:

membership in class Interval

Parameters:

x - point to test for membership

Returns:

true if x is in interval

intersect

public boolean intersect(Interval I)

Is there a nonzero intersection between this interval and the argument.

Parameters:

I - interval to be tested

Returns:

true if the intervals intersect

equals

public boolean equals(OpenInterval I)

Are intervals equal

Parameters:

I - interval object to be checked for equality

Returns:

true if both objects are equal as intervals

toString

public java.lang.String toString()

Return the contents of the interval as a String. return string representation of interval

Overrides:

toString in class Interval
