Function Interval.contains
Whether the given time point is within this interval.
Prototype
bool contains( TP timePoint ) const pure;
Parameters
Name | Description |
---|---|
timePoint | The time point to check for inclusion in this interval. |
Throws
DateTimeException
if this interval is empty
.
Examples
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
.
Prototype
bool contains( Interval interval ) const pure;
Parameters
Name | Description |
---|---|
interval | The interval to check for inclusion in this interval . |
Throws
DateTimeException
if either interval
is empty
.
Examples
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
.
Always returns false (unless this interval
is empty
), because an
interval
going to positive infinity can never be contained in a finite
interval
.
Prototype
bool contains( PosInfInterval!TP interval ) const pure;
Parameters
Name | Description |
---|---|
interval | The interval to check for inclusion in this interval . |
Throws
DateTimeException
if this interval
is empty
.
Examples
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
.
Always returns false (unless this interval
is empty
), because an
interval
beginning at negative infinity can never be contained in a
finite interval
.
Prototype
bool contains( NegInfInterval!TP interval ) const pure;
Parameters
Name | Description |
---|---|
interval | The interval to check for inclusion in this interval . |
Throws
DateTimeException
if this interval
is empty
.
Examples
assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).contains( NegInfInterval!Date(Date(1996, 5, 4))));
