Contextual::Call - call sub with caller's context
Version 0.01
use Contextual::Call qw(ccall); # invoke sub with your context. my $cc = ccall($coderef); ... some processes .. # and return value which was returned by $coderef and # is matched with context. return $cc->result;
"ccall" function can invoke a function undef specified context (default is caller's context) and reproduce return value of that invocation.
This function is useful when you will override a method which returns different values between scalar and list context.
This module can export ccall function.
$cc = ccall($coderef);
Call specified code-ref with your context, and return a Contextual::Call object which contains result of that call. You can get the result appropriate for context.
This function is shortcut to "new" constructor.
$obj = Contextual::Call->new({ context => wantarray, sub => $coderef });
Call specified code-ref with your context, and return a Contextual::Call object. This method is OO-style of "ccall" function.
return $obj->result();
Return result value with same context with ccall/new.
