Class tadt.standard.TemporalElement 

java.lang.Object
   |
   +----tadt.standard.TemporalElement
public class TemporalElement
extends Object
implements Anchorable
The TemporalElement class implements the Anchorable interface for TemporalElements. A TemporalElement is a set of "coalesced" Periods. So a better name would be CoalescedPeriodSet, but we stick with this name for purely historical reasons. There are several different ways to implement this beast, we adopt a representation as an array of Instants that delimit the interior Periods.

Constructor Index

o TemporalElement(Period[])
Construct a TemporalElement from an array of Periods.

Method Index

o asInstantArray()
Retrieve the array of Instants from this TemporalElement.
o asPeriodArray()
Retrieve the array of Periods from this TemporalElement.
o earliestInstant()
Returns the earliest Instant in the TemporalElement.
o earliestPeriod()
Returns the earliest Period in the TemporalElement.
o enumerateInstants()
Create an Enumeration of Instants in the Anchorable.
o enumeratePeriods()
Create an Enumeration of Periods in the Anchorable.
o equals(Anchorable)
Test for equality, needed only for supporting Hashtables, use equalTo for comparing TemporalElements directly.
o equals(TemporalElement)
Test for equality, needed only for supporting Hashtables, use equalTo for comparing TemporalElements directly.
o hashCode()
Generate the hash code value, needed for supporting Hashtables.
o image()
Build a nice string image of an TemporalElement, for debugging mostly
o kind()
Return the name of this class.
o latestInstant()
Returns the latest Instant in the TemporalElement.
o latestPeriod()
Returns the latest Period in the TemporalElement.
o newInstance(String, Instant[])
Construct a new instance of a TemporalElement, Interval combination
o newInstance(String, Period[])
Construct a new instance of a TemporalElement, Interval combination
