Functions

bool LSInterval::isVoid()

Returns true if the interval is void. A void interval is an empty interval with no valid start or end bounds.

Returns

True if the interval is void.

bool LSInterval::isDegenerate()

Returns true if the interval is degenerate. A degenerate interval is an interval with equal start and end bounds. It does not contain any element however.

Returns

True if the interval is degenerate.

lsint LSInterval::getStart()

Returns the start of the interval. Cannot be called on a void interval as it does not have a valid start.

Returns

Start of the interval.

lsint LSInterval::getEnd()

Returns the end of the interval. Cannot be called on a void interval as it does not have a valid end.

Returns

End of the interval.

lsint LSInterval::count() const

Returns the number of elements in the interval. A void or degenerate interval does not contain any element.

Returns

Number of elements in the interval.

bool LSInterval::contains(lsint value) const

Returns true if the interval contains the given value, false otherwise.

Parameters

value – element whose presence in this interval is to be tested.

Returns

True if the interval contains the value.

std::string LSInterval::toString() const

Returns a string representation of the interval.

Returns

String representation.
