CPANPLUS::Backend::RV − return value objects
### create a
CPANPLUS::Backend::RV object
$backend_rv = CPANPLUS::Backend::RV−>new(
ok => $boolean,
args => $args,
rv => $return_value
function => $calling_function );
### if you have a CPANPLUS::Backend::RV object
$passed_args = $backend_rv−>args; # args passed to
function
$ok = $backend_rv−>ok; # boolean indication overall
# result of the call
$function = $backend_rv−>function # name of the
calling
# function
$rv = $backend_rv−>rv # the actual return value
# of the calling function
This module provides return value objects for multi-module calls to CPANPLUS::Backend. In boolean context, it returns the status of the overall result (ie, the same as the "ok" method would).
new( ok
=> BOOL, args => DATA,
rv => DATA, [function => $method_name]
)
Creates a new CPANPLUS::Backend::RV object from the data
provided. This method should only be called by
CPANPLUS::Backend functions. The accessors may be used by
users inspecting an RV object.
All the argument names can be used as accessors later to retrieve the data.
Arguments:
|
ok |
Boolean indicating overall success |
args
The arguments provided to the function that returned this rv object. Useful to inspect later to see what was actually passed to the function in case of an error.
|
rv |
An arbitrary data structure that has the detailed return values of each of your multi-module calls. |
function
The name of the function that created this rv object. Can be explicitly passed. If not, "new()" will try to deduce the name from "caller()" information.
