NAME

SWISH::Prog::Doc - Document object class for passing to SWISH::Prog::Indexer

SYNOPSIS

# subclass SWISH::Prog::Doc
# and override filter() method

package MyDoc;
use base qw( SWISH::Prog::Doc );

sub filter {
  my $doc = shift;
  
  # alter url
  my $url = $doc->url;
  $url =~ s/my.foo.com/my.bar.org/;
  $doc->url( $url );
  
  # alter content
  my $buf = $doc->content;
  $buf =~ s/foo/bar/gi;
  $doc->content( $buf );
}

1;

DESCRIPTION

SWISH::Prog::Doc is the base class for Doc objects in the SWISH::Prog framework. Doc objects are created by SWISH::Prog::Aggregator classes and processed by SWISH::Prog::Indexer classes.

You can subclass SWISH::Prog::Doc and add a filter() method to alter the values of the Doc object before it is indexed.

METHODS

All of the following methods may be overridden when subclassing this module, but the recommendation is to override only filter().

new

Instantiate Doc object.

All of the following params are also available as accessors/mutators.

url
type
content
parser
modtime
size
action
debug
charset
data
version

Swish-e 2.x or Swish3 style headers. Value should be 2 or 3. Default is 2.

init

Calls filter() on object.

filter

Override this method to alter the values in the object prior to it being process()ed by the Indexer.

The default is to do nothing.

This method can also be set using the filter() callback in SWISH::Prog->new().

as_string

Return the Doc object rendered as a scalar string, ready to be indexed. This will include the proper headers. See SWISH::Prog::Headers.

NOTE: as_string() is also used if you use a Doc object as a string. Example:

print $doc->as_string;     # one way
print $doc;                # same thing
