aspect::advice::before
Aspect::Advice::Before(3pm) User Contributed Perl Documentation Aspect::Advice::Before(3pm)
NAME
Aspect::Advice::Before - Execute code before a function is called
SYNOPSIS
use Aspect;
before {
# Trace all calls to your module
print STDERR "Called my function " . $_->sub_name . "
";
# Shortcut calls to foo() to always be true
if ( $_->short_name eq 'foo' ) {
return $_->return_value(1);
}
# Add an extra flag to bar() but call as normal
if ( $_->short_name eq 'bar' ) {
$_->args( $_->args, 'flag' );
}
} call qr/^ MyModule::w+ $/
DESCRIPTION
The "before" advice type is used to execute advice code prior to entry into a target function. It is implemented by Aspect::Advice::Before.
As well as creating side effects that run before the main code, the "before" advice type is particularly useful for changing parameters or
shortcutting calls to functions entirely and replacing the value they would normally return with a different value.
Please note that the "highest" pointcut (Aspect::Pointcut::Highest) is incompatible with "before". Creating a "before" advice with a
pointcut tree that contains a "highest" pointcut will result in an exception.
If speed is important to your program then "before" is particular interesting as the "before" implementation is the only one that can take
advantage of tail calls via Perl's "goto" function, where the rest of the advice types need the more costly Sub::Uplevel to keep caller()
returning correctly.
