NAME

ModPerl::Global -- Perl API for manipulating special Perl lists

CONTENTS

Synopsis



  use ModPerl::Global ();
  my $package = MyApache2::Package;
 
  # make the END blocks of this package special
  ModPerl::Global::special_list_register(END => $package);
 
  # Execute all encoutered END blocks from this package now
  ModPerl::Global::special_list_call(    END => $package);
 
  # delete the list of END blocks
  ModPerl::Global::special_list_clear(   END => $package);



Description

ModPerl::Global provides an API to manipulate special perl lists. At the moment only the END blocks list is supported.

This API allows you to change the normal Perl behavior, and execute special lists when you need to.

For example ModPerl::RegistryCooker uses it to run END blocks in the scripts at the end of each request.

Before loading a module containing package $package, you need to register it, so the special blocks will be intercepted by mod_perl and not given to Perl. special_list_register does that. Later on when you want to execute the special blocks, special_list_call should be called. Unless you want to call the list more than once, clear the list with special_list_clear.

API

ModPerl::Global provides the following methods:

CWspecial_list_call

Call the special list



  $ok = special_list_call($key => $package);



arg1: $key ( string ) The name of the special list. At the moment only END is supported.
arg2: $package ( string ) what package to special list is for
ret: $ok ( boolean ) true value if $key is known, false otherwise.
since: 2.0.00

CWspecial_list_clear

Clear the special list



  $ok = special_list_clear($key => $package);



arg1: $key ( string ) The name of the special list. At the moment only END is supported.
arg2: $package ( string ) what package to special list is for
ret: $ok ( boolean ) true value if $key is known, false otherwise.
since: 2.0.00

CWspecial_list_register

Register the special list



  $ok = special_list_call($key => $package);



arg1: $key ( string ) The name of the special list. At the moment only END is supported.
arg2: $package ( string ) what package to special list is for
ret: $ok ( boolean ) true value if $key is known, false otherwise.
since: 2.0.00
Notice that you need to register the package before it is loaded. If you register it after, Perl has already compiled the END blocks and there are no longer under your control.
