std.datetime.interval.Interval.contains - multiple declarations

Function Interval.contains

Whether the given time point is within this interval.

bool contains (
  scope const TP timePoint
) const pure;

Parameters

NameDescription
timePoint The time point to check for inclusion in this interval.

Throws

DateTimeException if this interval is empty.

Example

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).contains(
            Date(1994, 12, 24)));

assert(Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).contains(
            Date(2000, 1, 5)));
assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).contains(
            Date(2012, 3, 1)));

Function Interval.contains

Whether the given interval is completely within this interval.

bool contains (
  scope const Interval interval
) const pure;

Parameters

NameDescription
interval The interval to check for inclusion in this interval.

Throws

DateTimeException if either interval is empty.

Example

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).contains(
            Interval!Date(Date(1990, 7, 6), Date(2000, 8, 2))));

assert(Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).contains(
            Interval!Date(Date(1999, 1, 12), Date(2011, 9, 17))));

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).contains(
            Interval!Date(Date(1998, 2, 28), Date(2013, 5, 1))));

Function Interval.contains

Whether the given interval is completely within this interval.

bool contains (
  scope const PosInfInterval!TP interval
) const pure;

Always returns false (unless this interval is empty), because an interval going to positive infinity can never be contained in a finite interval.

Parameters

NameDescription
interval The interval to check for inclusion in this interval.

Throws

DateTimeException if this interval is empty.

Example

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).contains(
            PosInfInterval!Date(Date(1999, 5, 4))));

Function Interval.contains

Whether the given interval is completely within this interval.

bool contains (
  scope const NegInfInterval!TP interval
) const pure;

Always returns false (unless this interval is empty), because an interval beginning at negative infinity can never be contained in a finite interval.

Parameters

NameDescription
interval The interval to check for inclusion in this interval.

Throws

DateTimeException if this interval is empty.

Example

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).contains(
            NegInfInterval!Date(Date(1996, 5, 4))));
