Sort::Key::Types(3pm) User Contributed Perl Documentation Sort::Key::Types(3pm)
NAME
Sort::Key::Types - handle Sort::Key data types
SYNOPSIS
use Sort::Key::Types qw(register_type);
register_type(Color => sub { $_->R, $_->G, $_->B }, qw(int, int, int));
# you better
# use Sort::Key::Register ...
DESCRIPTION
The Sort::Key family of modules can be extended to support new key types using this module (or the more friendly Sort::Key::Register).
FUNCTIONS
The following functions are provided:
Sort::Key::register_type($name, &gensubkeys, @subkeystypes)
registers a new datatype named $name defining how to convert it to a multikey.
&gensubkeys should convert the object of type $name passed on $_ to a list of values composing the multikey.
@subkeystypes is the list of types for the generated multikeys.
For instance:
Sort::Key::Types::register_type
'Person',
sub { $_->surname,
$_->name,
$_->middlename },
qw(str str str);
Sort::Key::Types::register_type
'Color',
sub { $_->R, $_->G, $_->B },
qw(int int int);
Once a datatype has been registered it can be used in the same way as types supported natively, even for defining new types, i.e.:
Sort::Key::Types::register_type
'Family',
sub { $_->father, $_->mother },
qw(Person Person);
SEE ALSO
Sort::Key, Sort::Key::Merger, Sort::Key::Register.
