Class Interval

  • All Implemented Interfaces:
    java.lang.Cloneable
    public class Interval
extends java.lang.Object
implements java.lang.Cloneable
    A class to represent a time interval. Specially useful to calculate time distance between events constrained by temporal constraints. If the interval is open, i.e., from -infinitum to +infinitum, the representation is created by using lowerBound = Long.MIN_VALUE and upperBound = Long.MAX_VALUE.

    • Method Detail

      • intersect

        public void intersect​(Interval another)
        Calculates the value of the intersection between this Interval and another interval. This is given by the following rule: lowerBound = max( this.lowerBound, another.lowerBound ) upperBound = min( this.upperBound, another.upperBound )
        Parameters:
        another - the other interval to calculate the intersection with.

      • add

        public void add​(Interval another)
        Calculates the path addition of this interval with another interval. This is given by the following rule: lowerBound = ( this.lowerBound == MIN || another.lowerBound == MIN ) ? MIN : this.lowerBound+another.lowerBound; upperBound = ( this.upperBound == MAX || another.upperBound == MAX ) ? MAX : this.upperBound+another.upperBound;
        Parameters:
        another - the other interval to add into this interval
