XS(3) User Contributed Perl Documentation XS(3)
NAME
Readonly::XS - Companion module for Readonly.pm, to speed up read-only scalar variables.
VERSION
This document describes version 1.05 of Readonly::XS, February 24, 2009.
SYNOPSIS
Install this module, but do not use it.
DESCRIPTION
The Readonly module (q.v.) is an effective way to create non-modifiable variables. However, it's relatively slow.
The reason it's slow is that is implements the read-only-ness of variables via tied objects. This mechanism is inherently slow. Perl
simply has to do a lot of work under the hood to make tied variables work.
This module corrects the speed problem, at least with respect to scalar variables. When Readonly::XS is installed, Readonly uses it to
access the internals of scalar variables. Instead of creating a scalar variable object and tying it, Readonly simply flips the SvREADONLY
bit in the scalar's FLAGS structure.
Readonly arrays and hashes are not sped up by this, since the SvREADONLY flag only works for scalars. Arrays and hashes always use the tie
interface.
Why implement this as a separate module? Because not everyone can use XS. Not everyone has a C compiler. Also, installations with a
statically-linked perl may not want to recompile their perl binary just for this module. Rather than render Readonly.pm useless for
these people, the XS portion was put into a separate module.
Programs that you write do not need to know whether Readonly::XS is installed or not. They should just "use Readonly" and let Readonly
worry about whether or not it can use XS. If the Readonly::XS is present, Readonly will be faster. If not, it won't. Either way, it will
still work, and your code will not have to change.
Your program can check whether Readonly.pm is using XS or not by examining the $Readonly::XSokay variable. It will be true if the XS
module was found and is being used. Please do not change this variable.
EXPORTS
None.
