NAME

CPANPLUS::Backend::RV - return value objects

SYNOPSIS

  1. ### create a CPANPLUS::Backend::RV object
  2. $backend_rv = CPANPLUS::Backend::RV->new(
  3. ok => $boolean,
  4. args => $args,
  5. rv => $return_value
  6. function => $calling_function );
  7. ### if you have a CPANPLUS::Backend::RV object
  8. $passed_args = $backend_rv->args; # args passed to function
  9. $ok = $backend_rv->ok; # boolean indication overall
  10. # result of the call
  11. $function = $backend_rv->function # name of the calling
  12. # function
  13. $rv = $backend_rv->rv # the actual return value
  14. # 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.
