NAME

Net::Radius::Server::Match - Base class for match methods

SYNOPSIS

  package My::Radius::Match;
  use base 'Net::Radius::Server::Match';

  __PACKAGE__->mk_accessors(qw/foo bar baz/);

  sub match_foo { ... }
  sub match_bar { ... }
  sub match_baz { ... }

  # Meanwhile, in a configuration file nearby...
  my $match = My::Radius::Match->new({ foo => 'x', bar => 'y' });
  my $match_sub = $match->mk;
  ...

  # Alternatively, in a more compact notation...
  my $match_sub = My::Radius::Match->mk({ foo => 'x', bar => 'y' });

DESCRIPTION

Net::Radius::Server::Match is a base class for developing "match" methods to be used in Net::Radius::Server rules.

->new($hashref)

Creates a new Net::Radius::Server::Match object. $hashref referenes a hash with the attributes that will apply to this object, so that multiple match methods (that will share the same underlying object) can be created and given to different rules.

$self->mk() or __PACKAGE__->mk($hashref)

This method returns a sub suitable for calling as a match method for a Net::Radius::Server rule. The resulting sub will return either NRS_MATCH_OK or NRS_MATCH_FAIL depending on its result.

The sub contains a closure where the object attributes -- Actually, the object itself -- are kept.

When invoked as an object method (ie, $self->mk()), no arguments can be given. The object is preserved as is within the closure.

When invoked as a class method (ie, __PACKAGE__->mk($hashref)), a new object is created with the given arguments and then, this object is preserved within the closure. This form is useful for compact filter definitions that require little or no surrounding code or holding variables.

->_match()

This method is internally called by the sub returned by the call to ->mk() and should not be called explicitly. This method iterates through the existing elements in the object -- It is assumed that it is a blessed hash ref, as left by Class::Accessor.

This method tries to invoke $self-match_$element(@_)>, passing the same arguments it receives - Note that normally, those are the same that were passed to the sub returned by the factory.

See the source of Net::Radius::Server::Match::Simple. This is much simpler than it sounds. Really.

The calls are done in "short circuit". This means that the first method returning NRS_MATCH_FAIL will cause this result to be returned.

Arguments with no corresponding match_* method are ignored. Arguments whose name start with "_" are also ignored.

By default, this method will return NRS_MATCH_OK.

Methods to Provide in Derived Classes

As shown in the example in the SYNOPSIS, your derived class must provide a match_* method for each attribute you define.

The method must return any of the NRS_MATCH_* constants to indicate its result.

EXPORT

None by default.
