NAME

CPANPLUS::Backend::RV - return value objects

SYNOPSIS

    ### 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

DESCRIPTION

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).

METHODS

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.
