Class Interval

java.lang.Object
org.drools.base.time.Interval
All Implemented Interfaces:
Cloneable
public class Interval extends Object implements 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 Details

    • 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
