TimeRange

public TimeRange(Date start,
                 Date end)

Method Detail

getDuration

public long getDuration()

getInterval

public TimeInterval getInterval()

This is a suggested interval to perform calculations such as aggregations over.

If you have a short time range you might want to aggregate over seconds, if you have decades of time range you should aggregate over year.

Obviously there is no hard and fast rule for this, but defining here gives a reasonable set of defaults which won't overload the average visualisation.

Returns:

a interval

isValid

public boolean isValid()

expand

public void expand(TimeRange r)

Expand this time range so that is encompasses the argument time range.

Parameters:

r - the r
