HxInterval Class¶

class hexaly.optimizer.HxInterval¶: Value type for interval expressions. Such value is obtained with HxExpression::value when the expression is an interval.

Summary¶

Methods¶
`is_void`	Returns true if the interval is void.
`is_degenerate`	Returns true if the interval is degenerate.
`start`	Returns the start of the interval.
`end`	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.

Special methods¶
`__str__`	Returns a string representation of this interval.
`__contains__`	Operator overloading for HxInterval.contains().
`__len__`	Returns the number of elements in this interval (same result as HxInterval.count()).
`__iter__`	Returns an iterator for the content of this interval.

Instance methods¶

HxInterval.is_void()¶

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

HxInterval.is_degenerate()¶

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.
Return type:: bool

HxInterval.start()¶

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

HxInterval.end()¶

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

HxInterval.count()¶

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

HxInterval.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

Special operators and methods¶

HxInterval.__str__()¶

Returns a string representation of this interval.

Returns:: String representation of this interval.
Return type:: str

HxInterval.__contains__(value)¶

Operator overloading for HxInterval.contains().

Returns:: True if the interval contains the value.
Return type:: bool

HxInterval.__len__()¶

Returns the number of elements in this interval (same result as HxInterval.count()).

Returns:: Number of elements in the interval.
Return type:: int

HxInterval.__iter__()¶: Returns an iterator for the content of this interval.
