Range

​

Range Objects

class Range()

A class representing a range with a start and end value.

Attributes:

• start int - The starting value of the range.
• end int - The ending value of the range.

​

frame_to_range

def frame_to_range(frame: int) -> Range

Convert a single frame to a Range.

Arguments:

• frame int - The single frame to be converted.

Returns:

• Range - A Range object with both start and end set to the input frame.

​

frames_to_ranges

def frames_to_ranges(frames: Collection[int]) -> Ranges

Create a sorted list (in ascending order) of non-overlapping run-length encoded ranges from a collection of frames.

Arguments:

• frames Collection[int] - A collection of integers representing frames.

Returns:

• Ranges - A list of Range objects representing the non-overlapping ranges.

​

ranges_to_list

def ranges_to_list(ranges: Ranges) -> List[List[int]]

Convert a list of Range objects to a list of lists (run-length encoded) of integers.

Arguments:

• ranges Ranges - A list of Range objects.

Returns:

• List[List[int]] - A list of lists where each inner list contains two integers, the start and end of a range.

​

range_to_ranges

def range_to_ranges(range_: Range) -> Ranges

Convert a single Range to a list of Ranges.

Arguments:

• range_ Range - The single Range to be converted.

Returns:

• Ranges - A list containing the input Range as its only element.

​

range_to_frames

def range_to_frames(range_: Range) -> List[int]

Convert a single Range (run-length encoded) to a list of integers.

Arguments:

• range_ Range - The single Range to be converted.

Returns:

• List[int] - A list of integers representing the frames within the range.

​

ranges_to_frames

def ranges_to_frames(range_list: Ranges) -> List[int]

Convert a list of Ranges (run-length encoded) to a list of integers.

Arguments:

• range_list Ranges - A list of Range objects.

Returns:

• List[int] - A sorted list of integers representing all frames within the ranges.

​

ranges_list_to_ranges

def ranges_list_to_ranges(range_list: List[List[int]]) -> Ranges

Convert a list of lists (run-length encoded) of integers to a list of Range objects.

Arguments:

• range_list List[List[int]] - A list of lists where each inner list contains two integers, the start and end of a range.

Returns:

• Ranges - A list of Range objects created from the input list of lists.

​

frames_class_to_frames_list

def frames_class_to_frames_list(frames_class: Frames) -> List[int]

Convert a Frames class (which can be an int, a list of ints, a Range, or a list of Ranges) to a list of integers.

Arguments:

• frames_class Frames - A Frames class which can be a single int, a list of ints, a Range object, or a list of Range objects.

Returns:

• List[int] - A sorted list of integers representing all frames within the input Frames class.

Raises:

• RuntimeError - If the input frames_class is of an unexpected type.
