Mail::Message::Body::String

body of a Mail::Message stored as single string

 Mail::Message::Body::String
   is a Mail::Message::Body
   is a Mail::Reporter
   Mail::Message::Body also extends Mail::Reporter
   is a Mail::Reporter

  See Mail::Message::Body

The body (content) of a message can be stored in various ways. In this documentation you will find the description of extra functionality you have when a message is stored as a single scalar.

Storing a whole message in one string is only a smart choice when the content is small or encoded. Even when stored as a scalar, you can still treat the body as if the data is stored in lines or an external file, but this will be slower.

Cast by encode()
A Mail::Message::Body::String object is to be created from a named file, but it is impossible to read that file to retrieve the lines within. Cast by new()
Cast by concatenate()
Cast by write()
The encoding or decoding of a message body encounters a character set which is not understood by Perl's Encode module. Cast by encode()
Fatal error: the specific $package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package. Cast by notImplemented()

Cast by write()
The data (message body) is encoded in a way which is not currently understood, therefore no decoding (or recoding) can take place. Cast by encode()
The data (message body) has been decoded, but the required encoding is unknown. The decoded data is returned. Cast by encode()
