Constructor Detail

TimeRange

public TimeRange(Timespec begin,
                 Timespec end)

Method Detail

getBegin

public Timespec getBegin()

withBegin

public TimeRange withBegin(Timespec b)

Returns a copy of this timerange with a different begin.

getEnd

public Timespec getEnd()

withEnd

public TimeRange withEnd(Timespec e)

toString in class Object

union

public static TimeRange union(TimeRange lhs,
                              TimeRange rhs)

Returns the union of two time ranges, that is, the range that can contain both time ranges.

intersect

public static TimeRange intersect(TimeRange lhs,
                                  TimeRange rhs)

Returns the intersection of two time ranges, that is, the widest possible range that is contained by both time ranges. Undefined behavior if the two timespecs do not overlap.

merge

public static TimeRange merge(TimeRange r,
                              Timespec t)

Merges a new timespec into this time range, and widens the time range if necessary to be wide enough to contain this time point.
