6 Locale::RecodeData - Abstract Base Class for Charset Converters
7
9 # For compatibility with Perl 5.005 and earlier, you must
10 # *use* the module before inheriting from it!
11 use qw (Locale::RecodeData);
12 use base qw (Locale::RecodeData);
13
15 The module Locale::RecodeData serves as an abstract base class to all
16 converters used by Locale::Recode(3).
17
18 Adding new conversion modules is currently not straightforward, and you
19 will have to edit the sources of some modules for that purpose.
20
21 First, you have to add your new converter class to the list found in
22 Locale::_Conversions(3), so that Locale::Recode(3) knows about its
23 presence. If there are valid aliases for the codeset of your
24 converter, you will also have to edit Locale::_Aliases(3).
25
26 Finally, you have to implement the (protected) conversion routine
27 _recode(). See below ("INTERFACE") for details.
28
30 new (from => FROM_CODESET, to => TO_CODESET)
31 The constructor takes two (named) arguments:
32
33 from The canonical name of the source codeset. Aliases have
34 already been resolved and the name is converted to
35 uppercase.
36
37 to The canonical name of the destination codeset. Aliases
38 have already been resolved and the name is converted to
39 uppercase.
40
41 You normally don't have to implement the constructor. The default
42 constructor implemented here will store the source and destination
43 codesets in the protected members "_from" and "_to".
44
46 The class implements one method:
47
48 _getError
49 Returns the (protected) member "_error".
50
52 New conversion classes must provide the following interface:
53
54 new (from => FROM_CODESET, to => TO_CODESET)
55 The constructor takes two (named) arguments:
56
57 from The canonical name of the source codeset. Aliases have
58 already been resolved and the name is converted to
59 uppercase.
60
61 to The canonical name of the destination codeset. Aliases
62 have already been resolved and the name is converted to
63 uppercase.
64
65 _getError
66 Should return the last error (as a string) or false if there was no
67 error.
68
69 This method is implemented in the base class already.
70
71 _recode STRINGREF
72 Should convert the argument "STRINGREF" in-place. In case of
73 failure, return false, and make provisions that the method
74 "_getError()" returns an informative error message.
