Class TemporalValue

java.lang.Object
  nars.entity.TemporalValue

public class TemporalValue
extends java.lang.Object

Temporal information, in terms of the internal clock of the system. In an Implication or Equivalence, the value indicates the interval from the first event to the second. In a Conjunction, the value can only be 0 (parallel) or 1 (suquential). In a Sentence, the value indicates the interval from when the sentence is created to when the event happens.

Method Summary

static boolean	closer(TemporalValue t1, TemporalValue t2, TemporalValue t) Check if the first temporal valie is closer to the given time than the second
static boolean	equal(TemporalValue t1, TemporalValue t2) Check if two temporal values have the same content
