NAME

       Crypt::Random::Source::Base - Abstract base class for Crypt::Random::Source classes

VERSION

       version 0.12

SYNOPSIS

           use Moo;
           extends qw(Crypt::Random::Source::Base);

DESCRIPTION

       This is an abstract base class.

       In the future it will be a role.

METHODS

   get $n, %args
       Gets $n random bytes and returns them as a string.

       This method may produce fatal errors if the source was unable to provide enough data.

   read $buf, $n, [ $off ]
       This method is cannibalized from IO::Scalar. It provides an IO::Handle work-alike.

       Note that subclasses override this to operate on a real handle directly if available.

   seed @stuff
       On supporting sources this method will add @stuff, whatever it may be, to the random seed.

       Some sources may not support this, so be careful.

   available
       This is a class method, such that when it returns true calling "new" without arguments on
       the class should provide a working source of random data.

       This is use by Crypt::Random::Source::Factory.

   rank
       This is a class method, with some futz value for a ranking, to help known good sources be
       tried before known bad (slower, less available) sources.

   get_data %Params
       Provided for compatibility with Crypt::Random
