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.
