       XML::SAX::EventMethodMaker - SAX event names, creation of methods from templates


       version 0.46


           use XML::SAX::EventMethodMaker qw(
               sax_event_names missing_methods compile_methods

         ## Getting event names by handler type and SAX version
           my @events          = sax_event_names;
           my @dtd_events      = sax_event_names "DTDHandler";
           my @sax1_events     = sax_event_names 1;
           my @sax1_dtd_events = sax_event_names 1, "DTDHandler";

         ## Figuring out what events a class or object does not provide
           my @missing = missing_methods $class, @events ;

         ## Creating all SAX event methods
           compile_methods $class, <<'TEMPLATE_END', sax_event_names;
           sub <EVENT> {
               my $self = shift;
               ... do something ...

               ## Pass the event up to the base class
               $self->SUPER::<EVENT>( @_ );

         ## Creating some methods
           compile_methods $class, <<'TEMPLATE_END', @method_names;

       In building SAX machines, it is often handle to build a set of event handlers from a
       common template.  This helper library (or class) provides the database of handler names,
       queryable by type, and


       XML::SAX::EventMethodMaker - SAX event names, creation of methods from templates


               my @names = sax_event_names @query_terms;

           Takes a list of query terms and returns all matching events.

           Query terms may be:
               - a SAX version number: 1 or 2 (no floating point or ranges)
               - Handler
               - DTDHandler
               - ContentHandler
               - DocumentHandler
               - DeclHandler
               - ErrorHandler
               - EntityResolver
               - LexicalHandler

           In addition to normal SAX events, there are also "parse" events:
               - ParseMethods

           Unrecognized query terms cause exceptions.

           If no query terms are provided, then all event names from all versions are returned
           except for parse methods (parse, parse_uri, ...).

           If any version numbers are supplied, then only events from those version numbers are
           returned.  No support for noninteger version numbers is provided, nor for ranges.  So
           far, only two SAX versions exist in Perl, 1 and 2.

           If any handler types are provided, then only events of those types are returned.
           Handler types are case insensitive.

           In other words, all returned events must match both a version number and a handler

           No support for boolean logic is provided.

               my @missing = missing_methods __PACKAGE__, @event_names;
               my @missing = missing_methods $object, @event_names;

           This subroutine looks to see if the object or class has declared event handler methods
           for the named events.  Any events that haven't been declared are returned.

           It is sufficient to use subroutine prototypes to prevent shimming AUTOLOADed (or
           otherwise lazily compiled) methods:

               sub start_document ;

               compile_methods __PACKAGE__, $template, @method_names;
               compile_methods $object,     $template, @method_names;

           Compiles the given template for each given event name, substituting the event name for
           the string <EVENT> or <METHOD> in the template.  There is no difference between these
           two tags, they are provided to only to let you make your templates more readable to

               compile_missing_methods __PACKAGE__, $template, @method_names;
               compile_missing_methods $objects,    $template, @method_names;

           Shorthand for calls like

               compile_methods __PACKAGE__, $template,
                   missing_methods __PACKAGE__, @method_names;
