Mail::Message::Construct::Text(3pm)			User Contributed Perl Documentation		       Mail::Message::Construct::Text(3pm)

NAME
Mail::Message::Construct::Text - capture a Mail::Message as text SYNOPSIS
my $text = $msg->string; my $text = "$msg"; # via overload my @text = $msg->lines; my @text = @$lines; # via overload my $fh = $msg->file; my $line = <$fh>; $msg->printStructure; DESCRIPTION
Complex functionality on Mail::Message objects is implemented in different files which are autoloaded. This file implements the functionality related to creating message replies. METHODS
The whole message as text $obj->file() Returns the message as file-handle. $obj->lines() Returns the whole message as set of lines. In LIST context, copies of the lines are returned. In SCALAR context, a reference to an array of lines is returned. $obj->printStructure([FILEHANDLE|undef],[INDENT]) Print the structure of a message to the specified FILEHANDLE or the selected filehandle. When explicitly "undef" is specified as handle, then the output will be returned as string. The message's subject and the types of all composing parts are displayed. INDENT specifies the initial indentation string: it is added in front of each line. The INDENT must contain at least one white-space. example: my $msg = ...; $msg->printStructure(*OUTPUT); $msg->printStructure; my $struct = $msg->printStructure(undef); # Possible output for one message: multipart/mixed: forwarded message from Pietje Puk (1550 bytes) text/plain (164 bytes) message/rfc822 (1043 bytes) multipart/alternative: A multipart alternative (942 bytes) text/plain (148 bytes, deleted) text/html (358 bytes) $obj->string() Returns the whole message as string.
