NAME

Apache2::Controller::Dispatch::HashTree - Hash tree dispatch for Apache2::Controller::Dispatch

VERSION

Version 1.000.110

SYNOPSIS

<Location "/subdir">
    SetHandler modperl
    PerlInitHandler MyApp::Dispatch
</Location>

# lib/MyApp::Dispatch:

package MyApp::Dispatch;
use base qw(
    Apache2::Controller::Dispatch::HashTree
);

# return a hash reference from dispach_map()
sub dispatch_map { return {
   foo => {
       default     => 'MyApp::C::Foo',
       bar => {
           biz         => 'MyApp::C::Biz',
           baz         => 'MyApp::C::Baz',
       },
   },
   default => 'MyApp::C::Default',
} }

This maps uri's to controller modules as follows:

/subdir/foo                    MyApp::C::Foo->default()

/subdir/foo/bar                MyApp::C::Foo->bar()

/subdir/foo/bar/zerm           MyApp::C::Foo->bar(), path_args == ['zerm']

/subdir/foo/bar/biz            MyApp::C::Biz->default()

/subdir/foo/biz/baz/noz/wiz    MyApp::C::Baz->noz(), path_args == ['wiz']

In the second example, if <MyApp::C::Foo> did not implement or allow <bar()> as a controller method, then this would select <MyApp::C::Foo-default()>>.

DESCRIPTION

Implements find_controller() for Apache2::Controller::Dispatch with a simple hash-based mapping. Uses substr to divide the uri and exists to check cached mappings, so it should be pretty fast.

This dispatches URI's in a case-insensitive fashion.

METHODS

find_controller

Find the controller and method for a given URI from the data set in the dispatch class module.
