LSInterval Class¶

class LSInterval¶

Value type for interval expressions. Such a value is obtained with LSExpression.value or with LSSolution.getValue().

See:	`LSModel`
See:	`LSExpression`

Summary¶

Methods¶
`isVoid`	Returns true if the interval is void.
`isDegenerate`	Returns true if the interval is degenerate.
`getStart`	Returns the start of the interval.
`getEnd`	Returns the end of the interval.
`count`	Returns the number of elements in the interval.
`contains`	Returns true if the interval contains the given value, false otherwise.
`toString`	Returns a string representation of the interval.

LSInterval.isVoid(val)¶

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.
Return type:	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.

Returns:	True if the interval is degenerate.
Return type:	bool

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.
Return type:	int

LSInterval.getEnd(value)¶

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.
Return type:	int

LSInterval.count(value)¶

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.
Return type:	int

LSInterval.contains(value)¶

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.
Return type:	bool

LSInterval.toString(value)¶

Returns a string representation of the interval.

Returns:	String representation.
Return type:	string
