timeInterval-class: Class 'timeInterval'

Description

An object from class "timeInterval" represents a time interval or an union of time intervals. Methods are defined for union, intersection, complement and other suitable operations.

Arguments

Objects from the Class

Objects can be created by calls of the form new("timeInterval", ...) or, preferably, timeInterval.

A "timeInterval" object represents the union of zero or more intervals of the form [left, right), i.e., closed on the left and open on the right (but see below the note about left = -Inf). The internal representation is always in a canonical disjoint form, such that the intervals do not overlap and do not touch at their end points.

The start of an interval can be -Inf and the end can be Inf. When the left side of an interval is -Inf, it is currently unspecified if -Inf belongs to it. In other words, it is not defined whether timeInterval[-Inf, b] represents \((-\infty, b)\) or \([-\infty, b)\). Feedback on this will be appreciated. The current code treats it as \([-\infty, b)\).
