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.
|
|
|
|
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.
