NAME

       Plucene::Index::FieldInfos - a collection of FieldInfo objects

SYNOPSIS

	       my $fis = Plucene::Index::FieldInfos->new($dir_name);
	       my $fis = Plucene::Index::FieldInfos->new($dir_name, $file);

	       $fis->add(Plucene::Document $doc, $indexed);
	       $fis->add(Plucene::Index::FieldInfos $other_fis, $indexed);
	       $fis->add($name, $indexed);

	       $fis->write($path);

	       my @fields = $fis->fields;

	       my $field_number = $fis->field_number($name);
	       my   $field_info = $fis->field_info($name);
	       my   $field_name = $fis->field_name($number);
	       my   $num_fields = $fis->size;

DESCRIPTION

       This is a collection of field info objects, which happen to live in the field infos file.

METHODS

   new
	       my $fis = Plucene::Index::FieldInfos->new($dir_name);
	       my $fis = Plucene::Index::FieldInfos->new($dir_name, $file);

       This will create a new Plucene::Index::FieldInfos object with the passed directory and optional filename.

   add
	       $fis->add(Plucene::Document $doc, $indexed);
	       $fis->add(Plucene::Index::FieldInfos $other_fis, $indexed);
	       $fis->add($name, $indexed);

       This will add the fields from a Plucene::Document or a Plucene::Index::FieldsInfos to the field infos file.

       It is also possible to pass the name of a field and have it added to the file.

   field_number
	       my $field_number = $fis->field_number($name);

       This will return the field number of the field with $name. If there is no match, then -1 is returned.

   fields
	       my @fields = $fis->fields;

       This will return all the fields.

   field_info
	       my $field_info = $fis->field_info($name);

       This will return the field info for the field called $name.

   field_name
	       my $field_name = $fis->field_name($number);

       This will return the field name for the field whose number is $number.

   size
	       my $num_fields = $fis->size;

       This returns the number of field info objects.

   write
	       $fis->write($path);

       This will write the field info objects to $path.
