Routines supplied by class Uni

NFD inherits from class Uni, which provides the following routines:

(Uni) method new

method new(*@codes --> Uni:D)

Creates a new Uni instance from the given codepoint numbers.

(Uni) method list

Defined as:

method list(Uni:D:)

Returns a Seq of integer codepoints.

(Uni) method NFC

method NFC(Uni:D: --> NFC:D)

Returns a NFC (Normal Form Composed)-converted version of the invocant.

(Uni) method NFD

method NFD(Uni:D: --> NFD:D)

Returns a NFD (Normal Form Decomposed)-converted version of the invocant.

(Uni) method NFKC

method NFKC(Uni:D: --> NFKC:D)

Returns a NFKC (Normal Form Compatibility Composed)-converted version of the invocant.

(Uni) method NFKD

method NFKD(Uni:D: --> NFKD:D)

Returns a NFKD (Normal Form Compatibility Decomposed)-converted version of the invocant.

(Uni) method codes

method codes(Uni:D: --> Int:D)

Returns the number of codepoints in the invocant.

(Uni) method elems

method elems(Uni:D: --> Int:D)

Returns the number of codepoints in the invocant.

Routines supplied by role Positional

NFD inherits from class Uni, which does role Positional, which provides the following routines:

(Positional) method of

method of()

Returns the type constraint for elements of the positional container, that is, the T in the definition above, which, as it can be seen, defaults to Mu. It is returned as a type object.

my @þ;
say @þ.of.^name;   # OUTPUT: «Mu␤ 
my Str @þð;
say @þð.of.raku;   # OUTPUT: «Str␤» 
say (my int @).of# OUTPUT: «(int)␤» 

(Positional) method elems

method elems()

Should return the number of available elements in the instantiated object.

(Positional) method AT-POS

method AT-POS(\position)

Should return the value / container at the given position.

(Positional) method EXISTS-POS

method EXISTS-POS(\position)

Should return a Bool indicating whether the given position actually has a value.

(Positional) method STORE

method STORE(\values:$INITIALIZE)

This method should only be supplied if you want to support the:

my @a is Foo = 1,2,3;

syntax for binding your implementation of the Positional role.

Should accept the values to (re-)initialize the object with. The optional named parameter will contain a True value when the method is called on the object for the first time. Should return the invocant.
