Weekdays class

Utilities to encode and decode the days in a week into an 8-bit bitfield. A bitfield represents one week with each bit representing a day. It is big-endian with the first bit in the bitfield always being unused.

That is to say, it start with the day with the largest value (Sunday) at the 2nd left-most bit. For example 0100 0100, will represent Sunday and Wednesday.

Static Methods

decode(int encoded) → Iterable<int>

Decodes the bitfield into days, i.e. (1 to 7) of a week. encoded should be between 0 and 128.

encode(Iterable<int> week) → int

Encodes the days of a week into a bitfield. The length of week should be less than or equal to 7 with elements ranging from 1 to 7.

parse(int encoded) → Iterable<bool>

Parses the bitfield into booleans, i.e. true if a digit is 1. encoded should be between 0 and 128. The returned Iterable is little-endian with true indicating the presence of a day.

unparse(Iterable<bool> week) → int

Encodes the booleans into a bitfield. The length of week should be 7. week is expected to be little-endian with true indicating the presence of a day.
