SYNOPSIS

         print $ct->get_attribute('charset')->value();

DESCRIPTION

       This class represents a single attribute belonging to a header. An attribute consists of a
       name and value, with optional charset and language information.

API

       This class supports the following methods:

Courriel::HeaderAttribute->new( ... )

       This method creates a new object. It accepts the following parameters:

       ·   name

           The name of the attribute. This should be a non-empty string.

       ·   value

           The value of the attribute. This can be empty.

       ·   charset

           The charset for the value. If the value contains any non-ASCII data, this will always
           be "UTF-8", otherwise the default is "us-ascii".

       ·   language

           The language for the attribute's value. It should be a valid ISO language code like
           "en-us" or "zh". This is optional.

   $attribute->name()
       The attribute name as passed to the constructor.

   $attribute->value()
       The attribute value as passed to the constructor.

   $attribute->charset()
       The attribute's charset.

   $attribute->language()
       The attribute's language.

   $attribute->as_string()
       This returns the attribute in a form suitable for putting in an email. This may involve
       escaping, quoting, splitting up, and otherwise messing with the value.

       If the value needs to be split across continuations, each name/value pair is returned
       separate by a space, but not folded across multiple lines.

   $attribute->stream_to( output => $output )
       This method will send the stringified attribute to the specified output. The output can be
       a subroutine reference, a filehandle, or an object with a "print()" method. The output may
       be sent as a single string, as a list of strings, or via multiple calls to the output.

ROLES

       This class does the "Courriel::Role::Streams" role.
