NAME

    namespace - Perl pragma to use like C++ namespace aliasing

SYNOPSIS

     use namespace File => IO::File;

     my $fh = new File "foo", O_CREAT|O_WRONLY;

     if( defined $fh )

     {

         print $fh "bar\n";

         $fh->close;

     }

DESCRIPTION

    Allow aliasing namespace. May be useful for reusability increase.

     use namespace ALIAS => PACKAGE 

        [, qw/IMPORT_LIST [ ::SUBPACKAGE [ IMPORT_LIST ]] /];

     ALIAS and PACKAGE is required parameters;

     IMPORT_LIST is the usual list of import.

    Also may be undefined namespace and they subnamespaces:

     no namespace ALIAS;

    If ALIAS begin with '::', then alias will be expandet to caller

    namespace. If following example of pragma namespace called from main::

    module, then alias will be expandet to main::ALIAS::.

     use namespace ::ALIAS => PACKAGE

    

EXAMPLES

     EXAMPLE 1

     use namespace DOM => XML::DOM, qw/$VERSION ::Document $VERSION/;

        # DOM is alias for XML::DOM

        #       $VERSION from XML::DOM will be imported to DOM

        #

        # ::Document subpackage of XML::DOM will be aliased to DOM::Document

        #       $VERSION from XML::DOM::Document will be imported to DOM::Document

     my $doc = new DOM::Document;

     print "Current used DOM version is $DOM::VERSION \n";

     no namespace DOM;

        # namespace DOM and all subnamespaces will be destroyed

     EXAMPLE 2

     use namespace DOM => XML::DOM, qw/::Document/;

     # or

     # use namespace DOM => XML::Sablotron::DOM, qw/:constants ::Document/;

     my $doc = new DOM::Document;

     print "Constant 'TEXT_NODE' = ", TEXT_NODE;
