universal::exports

UNIVERSAL::exports(3pm) 				User Contributed Perl Documentation				   UNIVERSAL::exports(3pm)

NAME

       UNIVERSAL::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.

Methods
       UNIVERSAL::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).
