NAME
Catalyst::Controller::SRU - Dispatch SRU methods with Catalyst SYNOPSIS
package MyApp::Controller::SRU; # use it as a base controller use base qw( Catalyst::Controller::SRU ); # explain, scan and searchretrieve methods sub explain { my ( $self, $c, $sru_request, # ISA SRU::Request::Explain $sru_response, # ISA SRU::Response::Explain ) = @_; } sub scan { my ( $self, $c, $sru_request, # ISA SRU::Request::Scan $sru_response, # ISA SRU::Response::Scan $cql, # ISA CQL::Parser root node ) = @_; } sub searchRetrieve { my ( $self, $c, $sru_request, # ISA SRU::Request::SearchRetrieve $sru_response, # ISA SRU::Response::SearchRetrieve $cql, # ISA CQL::Parser root node ) = @_; } DESCRIPTION
This module allows your controller class to dispatch SRU actions ("explain", "scan", and "searchRetrieve") from its own class. METHODS
index : Private This method will create an SRU request, response and possibly a CQL object based on the type of SRU request it finds. It will then pass the data over to your customized method. SEE ALSO
