DTA::CAB::Format::perl is a DTA::CAB::Format datum parser/formatter which reads & writes data as perl code via eval() and Data::Dumper respectively.

Globals

Variable: @ISA

DTA::CAB::Format::Perl inherits from DTA::CAB::Format.

Filenames

DTA::CAB::Format::Perl registers the filename regex:

 /\.(?i:prl|pl|perl|dump)$/

with DTA::CAB::Format.

Constructors etc.

new

 $fmt = CLASS_OR_OBJ->new(%args);

Constructor.

%args, %$fmt:

 ##---- Input
 doc    => $doc,                 ##-- buffered input document
 ##
 ##---- Output
 dumper => $dumper,              ##-- underlying Data::Dumper object
 ##
 ##---- INHERITED from DTA::CAB::Format
 #encoding => $encoding,         ##-- n/a
 level     => $formatLevel,      ##-- sets Data::Dumper->Indent() option
 outbuf    => $stringBuffer,     ##-- buffered output

Methods: Persistence

noSaveKeys

 @keys = $class_or_obj->noSaveKeys();

Override returns list of keys not to be saved. This implementation returns qw(doc outbuf).

Methods: Input

close

 $fmt = $fmt->close();

Override: close currently selected input source.

fromString

 $fmt = $fmt->fromString($string)

Override: select input from the string $string.

parsePerlString

 $fmt = $fmt->parsePerlString($str);

Evaluates $str as perl code, which is expected to return a DTA::CAB::Document object (or something which can be massaged into one), and sets $fmt->{doc} to this new document object.

parseDocument

 $doc = $fmt->parseDocument();

Returns the current contents of $fmt->{doc}, e.g. the most recently parsed document.

Methods: Output

flush

 $fmt = $fmt->flush();

Override: flush accumulated output.

toString

 $str = $fmt->toString();
 $str = $fmt->toString($formatLevel)

Override: flush buffered output document to byte-string. This implementation just returns $fmt->{outbuf}, which should already be a byte-string, and has no need of encoding.

putToken

 $fmt = $fmt->putToken($tok);

Override: writes a token to the output buffer (non-destructive on $tok).

putSentence

 $fmt = $fmt->putSentence($sent);

Override: write a sentence to the outupt buffer (non-destructive on $sent).

putDocument

 $fmt = $fmt->putDocument($doc);

Override: write a document to the outupt buffer (non-destructive on $doc).
