UNIVERSAL::exports(3) User Contributed Perl DocumentationUNIVERSAL::exports(3)NAMEUNIVERSAL::exports - Lightweight, universal exporting of variables
SYNOPSIS
package Foo;
use UNIVERSAL::exports;
# Just like Exporter.
@EXPORT = qw($This &That);
@EXPORT_OK = qw(@Left %Right);
# Meanwhile, in another piece of code!
package Bar;
use Foo; # exports $This and &That.
DESCRIPTION
This is an alternative to Exporter intended to provide a universal,
lightweight subset of its functionality. It uses Exporter::Lite, so
look there for details.
Additionally, "exports()" is provided to find out what symbols a module
exports.
UNIVERSAL::exports places its methods in the UNIVERSAL namespace, so
there is no need to subclass from it.
MethodsUNIVERSAL::exports has two public methods, import() derived from
Exporter::Lite, and exports().
import
Some::Module->import;
Some::Module->import(@symbols);
This is Exporter::Lite's import() method. Look in Exporter::Lite
for details.
exports
@exported_symbols = Some::Module->exports;
Some::Module->exports($symbol);
Reports what symbols are exported by Some::Module. With no
arguments, it simply returns a list of all exportable symbols.
Otherwise, it reports if it will export a given $symbol.
DIAGNOSTICS
'"%s" is not exported by the %s module'
Attempted to import a symbol which is not in @EXPORT or @EXPORT_OK.
'Can\'t export symbol: %s'
Attempted to import a symbol of an unknown type (ie. the leading
$@% salad wasn't recognized).
