| Summary : Load subroutines only on demand
|
Description :
The *AutoLoader* module works with the *AutoSplit* module and the \'__END__\'
token to defer the loading of some subroutines until they are used rather
than loading them all at once.
To use *AutoLoader*, the author of a module has to place the definitions of
subroutines to be autoloaded after an \'__END__\' token. (See perldata.) The
*AutoSplit* module can then be run manually to extract the definitions into
individual files _auto/funcname.al_.
*AutoLoader* implements an AUTOLOAD subroutine. When an undefined
subroutine in is called in a client module of *AutoLoader*, *AutoLoader*\'s
AUTOLOAD subroutine attempts to locate the subroutine in a file with a name
related to the location of the file from which the client module was read.
As an example, if _POSIX.pm_ is located in _/usr/local/lib/perl5/POSIX.pm_,
*AutoLoader* will look for perl subroutines *POSIX* in
_/usr/local/lib/perl5/auto/POSIX/*.al_, where the \'.al\' file has the same
name as the subroutine, sans package. If such a file exists, AUTOLOAD will
read and evaluate it, thus (presumably) defining the needed subroutine.
AUTOLOAD will then \'goto\' the newly defined subroutine.
Once this process completes for a given function, it is defined, so future
calls to the subroutine will bypass the AUTOLOAD mechanism.
