NAME

App::CallDispatcher - synchronous (potentially remote) call_dispatcher invocation

SYNOPSIS

    use App;

    $context = App->context();
    $call_dispatcher = $context->service("CallDispatcher");  # or ...
    $call_dispatcher = $context->call_dispatcher();

    $call_dispatcher->call($request, $response);
    $response = $call_dispatcher->call($request);
    $response = $call_dispatcher->call(%named);

DESCRIPTION

A CallDispatcher service is a means by which a function call (perhaps remote) may be made synchronously.

Class Group: CallDispatcher

The following classes might be a part of the CallDispatcher Class Group.

• Class: App::CallDispatcher

• Class: App::CallDispatcher::SOAP
• Class: App::CallDispatcher::pRPC
• Class: App::CallDispatcher::PlRPC
• Class: App::CallDispatcher::Messaging

Class: App::CallDispatcher

A CallDispatcher service is a means by which a function call (perhaps remote) may be made synchronously or asynchronously.

Constructor Methods:

new()

The constructor is inherited from App::Service.

Public Methods:

call()

    * Signature: @returnvals = $call_dispatcher->call($service, $name, $method, $args);
    * Param:     $service           string  [in]
    * Param:     $name              string  [in]
    * Param:     $method            string  [in]
    * Param:     $args              ARRAY   [in]
    * Return:    @returnvals        any
    * Throws:    App::Exception::CallDispatcher
    * Since:     0.01

    Sample Usage: 

    @returnvals = $call_dispatcher->call("Repository","db",
        "get_rows",["city",{city_cd=>"LAX"},["city_cd","state","country"]]);

The default call dispatcher is a local call dispatcher. It simply passes the call() on to the local context for execution. It results in an in-process method call rather than a remote method call.

Protected Methods:

service_type()

Returns 'CallDispatcher';

    * Signature: $service_type = App::CallDispatcher->service_type();
    * Param:     void
    * Return:    $service_type  string
    * Since:     0.01

    $service_type = $cdisp->service_type();
