Interval

public Interval(int min,
                int max)

It creates an interval with a given minimum and maximal value.

Parameters:

min - the minimal value in the interval (the left bound).

max - the maximal value in the interval (the right bound).

Method Detail

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

eq

public boolean eq(Interval interval)

It checks equality between intervals.

Parameters:

interval - the inerval to which the comparison is made.

Returns:

true if an input interval is equal to this one.

max

public int max()

It returns the right bound of the interval (maximum value).

Returns:

the maximal value from the interval.

min

public int min()

It returns the left range of the interval (minimum value).

Returns:

the minimal value from the interval.

singleton

public boolean singleton()

It checks if an intervals contains only one value (singleton).

Returns:

true if domain has only one value.

singleton

public boolean singleton(int c)

It checks if an intervals contains only value c.

Parameters:

c - integer value to which the singleton is compared to.

Returns:

true if variable has a singleton domain and it is equal to value c.
