SGML::Notation - an data type defined in SGML or XML

SYNOPSIS

Top

  $name = $notation->name;
  $system_id = $notation->system_id;
  $public_id = $notation->public_id;
  $generated_id = $notation->generated_id;

  $notation->iter;

  $notation->accept($visitor, ...);

  The following are defined for type compatibilty:

  $notation->as_string([$context, ...]);
  $notation->accept_gi($visitor, ...);
  $notation->children_accept($visitor, ...);
  $notation->children_accept_gi($visitor, ...);

DESCRIPTION

Top

An SGML::Notation contains the type definition defined in a document instance, with the possible `generated_id' generated by the parser. Within a grove, any notation with the same name refers to the same SGML::Notation object.

SGML::Notation objects occur as the value of element attributes or as a member of external entities.

$notation->name returns the name of the notation.

$notation->accept($visitor[, ...]) issues a call back to $visitor->visit_SGML_Notation($notation[, ...]). Note that SGML::Notation objects are never primary children of an SGML::Element object and will not ordinarily occur while simply visiting a grove.

$notation->as_string returns an empty string.

$notation->accept_gi($visitor[, ...]) is implemented as a synonym for accept.

children_accept and children_accept_gi do nothing.
