Mail::Message::Body::String(3) User Contributed Perl Documentation NAME Mail::Message::Body::String - body of a Mail::Message stored as single string INHERITANCE Mail::Message::Body::String is a Mail::Message::Body is a Mail::Reporter Mail::Message::Body also extends Mail::Reporter is a Mail::Reporter SYNOPSIS See Mail::Message::Body DESCRIPTION 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. Extends "DESCRIPTION" in Mail::Message::Body.

DIAGNOSTICS Warning: Content-Transfer-Encoding '$te' requires explicit charset, defaulted to utf-8. Cast by encode() Fault: Unable to read file $name for message body scalar: $! 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() Error: cannot concatenate element $which Cast by concatenate() Fault: cannot open $file to write body: $! Cast by write() Warning: charset '$name' is not known. The encoding or decoding of a message body encounters a character set which is not understood by Perl's Encode module. Cast by encode() Error: class $package does not implement method $method. 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() Error: class $package does not implement method $method. 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() Fault: error closing $file after write body: $! Cast by write() Warning: no decoder defined for transfer encoding '$encoding'. 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() Warning: no encoder defined for transfer encoding '$encoding'. The data (message body) has been decoded, but the required encoding is unknown. The decoded data is returned. Cast by encode() Error: no filename parameter for write() body. Cast by write() Error: part number needs multi-part or nested. Cast by partNumberOf() Error: unknown line terminator '$eol'.
