Class Unicode

Define character sets etc for Unicode strings.

See base class for full documentation.

Instance Methods

__init__(self)
min and max define the range of values that char_to_code will map characters to (inclusive).

source code

code_to_char(self, code)
Convert a code - an integer value between min and max, that maps the alphabet to a contiguous set of integers - to a character in the alphabet.

source code

char_to_code(self, char)
Convert a character in the alphabet to a code - an integer value between min and max, that maps the alphabet to a contiguous set of integers.

source code

coerce(self, char)
Force a character in str, unicode, or the alphabet itself, to be a member of the alphabet.

source code

join(self, *strings)
Construct a word in the alphabet, given a list of words and/or characters.

source code

to_str(self, char)
Display the character.

source code

digit(self, char)
Test whether the character is a digit or not.

source code

space(self, char)
Test whether the character is a whitespace or not.

source code

word(self, char)
Test whether the character is a word character or not.

source code

unpack(self, char, flags)
Return either (True, (lo, hi)) or (False, char)

Method Details

init(self)
(Constructor)

min and max define the range of values that char_to_code will map characters to (inclusive).

Overrides: object.__init__: (inherited documentation)

code_to_char(self, code)

Convert a code - an integer value between min and max, that maps the alphabet to a contiguous set of integers - to a character in the alphabet.

Overrides: base.BaseAlphabet.code_to_char: (inherited documentation)

char_to_code(self, char)

Convert a character in the alphabet to a code - an integer value between min and max, that maps the alphabet to a contiguous set of integers.

Overrides: base.BaseAlphabet.char_to_code: (inherited documentation)

coerce(self, char)

Force a character in str, unicode, or the alphabet itself, to be a member of the alphabet.

Overrides: base.BaseAlphabet.coerce: (inherited documentation)

join(self, *strings)

Construct a word in the alphabet, given a list of words and/or characters.

Overrides: base.BaseAlphabet.join: (inherited documentation)

to_str(self, char)

Display the character.

Note - this is the basis of hash and equality for intervals, so must be unique, repeatable, etc.

Overrides: base.BaseAlphabet.to_str

digit(self, char)

Test whether the character is a digit or not.

Overrides: base.BaseAlphabet.digit: (inherited documentation)

space(self, char)

Test whether the character is a whitespace or not.

Overrides: base.BaseAlphabet.space: (inherited documentation)

word(self, char)

Test whether the character is a word character or not.

Overrides: base.BaseAlphabet.word: (inherited documentation)

unpack(self, char, flags)

Return either (True, (lo, hi)) or (False, char)

Overrides: base.BaseAlphabet.unpack
