NAME

Mail::Box::Parser::Perl - reading messages from file using Perl

INHERITANCE

Mail::Box::Parser::Perl
  is a Mail::Box::Parser
  is a Mail::Reporter

SYNOPSIS

DESCRIPTION

The Mail::Box::Parser::Perl implements parsing of messages in Perl. This may be a little slower than the C based parser Mail::Box::Parser::C, but will also work on platforms where no C compiler is available.

Extends "DESCRIPTION" in Mail::Box::Parser.

METHODS

Extends "METHODS" in Mail::Box::Parser.

Constructors

Extends "Constructors" in Mail::Box::Parser.

$class->new(%options)

Inherited, see "METHODS" in Mail::Box::Parser

-Option           --Defined in       --Default
 file                                  undef
 filename                              <required>
 fix_header_errors  Mail::Box::Parser  false
 mode                                  'r'
 trusted            Mail::Box::Parser  false
file => $filehandle

Any IO::File or GLOB $filehandle which can be used to read the data from. In case this option is specified, the filename is informational only.

filename => FILENAME

The name of the file to be read.

fix_header_errors => BOOLEAN
mode => $mode

File open $mode, which defaults to 'r', which means `read-only'. See perldoc -f open for possible modes. Only applicable when no file is specified.

trusted => BOOLEAN

Attributes

Extends "Attributes" in Mail::Box::Parser.

$any->defaultParserType( [$class] )

Inherited, see "Attributes" in Mail::Box::Parser

$obj->file()

$obj->filename()

Returns the name of the file this parser is working on.

$obj->fixHeaderErrors( [BOOLEAN] )

Inherited, see "Attributes" in Mail::Box::Parser

$obj->openMode()

$obj->trusted()

Inherited, see "Attributes" in Mail::Box::Parser

Parsing

Extends "Parsing" in Mail::Box::Parser.

$obj->bodyAsFile( $fh [$chars, [$lines]] )

Inherited, see "Parsing" in Mail::Box::Parser

$obj->bodyAsList( [$chars, [$lines]] )

Inherited, see "Parsing" in Mail::Box::Parser

$obj->bodyAsString( [$chars, [$lines]] )

Inherited, see "Parsing" in Mail::Box::Parser

$obj->bodyDelayed( [$chars, [$lines]] )

Inherited, see "Parsing" in Mail::Box::Parser

$obj->closeFile()

Close the file which was being parsed.

$obj->fileChanged()

Returns whether the file which is parsed has changed after the last time takeFileInfo() was called.

$obj->filePosition( [$position] )

Returns the location of the next byte to be used in the file which is parsed. When a $position is specified, the location in the file is moved to the indicated spot first.

$obj->lineSeparator()

Inherited, see "Parsing" in Mail::Box::Parser

$obj->openFile(%options)

[3.012] Open the file to be parsed.

$obj->readHeader()

Inherited, see "Parsing" in Mail::Box::Parser

$obj->restart(%options)

Restart the parser on a certain file, usually because the content has changed. The %options are passed to openFile().

$obj->start(%options)

Start the parser by opening a file.

-Option--Default
 file    undef
file => FILEHANDLE|undef

The file is already open, for instance because the data must be read from STDIN.

$obj->stop()

Stop the parser, which will include a close of the file. The lock on the folder will not be removed (is not the responsibility of the parser). Improves base, see "Parsing" in Mail::Box::Parser

$obj->takeFileInfo()

Capture some data about the file being parsed, to be compared later.

Error handling

Extends "Error handling" in Mail::Box::Parser.

$obj->AUTOLOAD()

Inherited, see "Error handling" in Mail::Reporter

$obj->notImplemented()

Inherited, see "Error handling" in Mail::Reporter

Cleanup

Extends "Cleanup" in Mail::Box::Parser.

$obj->DESTROY()

Inherited, see "Cleanup" in Mail::Reporter

DIAGNOSTICS

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: filename or handle required to create a parser.

Cast by new()

Error: parser $type does not extend $pkg.

Cast by defaultParserType()

Warning: unexpected end of header in $file:\n $line

Cast by readHeader()
