NegInfInterval.shift

std datetime interval NegInfInterval

Shifts the end of this interval forward or backwards in time by the given duration (a positive duration shifts the interval forward; a negative duration shifts it backward). Effectively, it does end += duration.

  1. void shift(D duration)
    struct NegInfInterval(TP)
    pure nothrow
    void
    shift
    (
    D
    )
    (
    D duration
    )
    if (
    __traits(compiles, end + duration)
    )
  2. void shift(T years, T months, AllowDayOverflow allowOverflow)

Parameters

duration D

The duration to shift the interval by.

Examples

auto interval1 = NegInfInterval!Date(Date(2012, 4, 5));
auto interval2 = NegInfInterval!Date(Date(2012, 4, 5));

interval1.shift(dur!"days"(50));
assert(interval1 == NegInfInterval!Date(Date(2012, 5, 25)));

interval2.shift(dur!"days"(-50));
assert(interval2 == NegInfInterval!Date( Date(2012, 2, 15)));
