spawn

    my $poe = POE::Component::IKC::ClientLite->spawn( %params );

Creates a new PoCo::IKC::ClientLite object. Parameters are supposedly compatible with PoCo::IKC::Client, but unix sockets aren't handled yet... What's more, there are 3 additional parameters:

block_size

Size, in octets (8 bit bytes), of each block that is read from the socket at a time. Defaults to 65535.

timeout

Time, in seconds, that "call" and "post_respond" will wait for a response. Defaults to 30 seconds.

connect_timeout

Time, in seconds, to wait for a phase of the connection negotiation to complete. Defaults to "timeout". There are 4 phases of negotiation, so a the default "connect_timeout" of 30 seconds means it could potentialy take 2 minutes to connect.

protocol

Which IKC negociation protocol to use. The original protocol ("IKC") was synchronous and slow. The new protocol ("IKC0") sends all information at once. IKC0 will degrade gracefully to IKC, if the client and server don't match.

Default is IKC0.

connect

    $poe->connect or die $poe->error;

Connects to the remote kernel if we aren't already. You can use this method to make sure that the connection is open before trying anything.

Returns true if connection was successful, false if not. You can check "error" to see what the problem was.

disconnect

error

    my $error=POE::Component::IKC::ClientLite::error();
    $error=$poe->error();

Returns last error. Can be called as a object method, or as a global function.

post

    $poe->post($specifier, $data);

Posts the event specified by $specifier to the remote kernel. $data is any parameters you want to send along with the event. It will return 1 on success (ie, data could be sent... not that the event was received) and undef() if we couldn't connect or reconnect to remote kernel.

post_respond

    my $ret=$poe->post_respond($specifier, $data);

Posts the event specified by $specifier to the remote kernel. $data is any parameters you want to send along with the event. It waits until the remote kernel sends a message back and returns it's payload. Waiting timesout after whatever you value you gave to POE::Component::IKC::Client->spawn.

Events on the far side have to be aware of post_respond. In particular, ARG0 is not $data as you would expect, but an arrayref that contains $data followed by a specifier that should be used to post back.

    sub my_event
    {
        my($kernel, $heap, $args)=@_[KERNEL, HEAP, ARG0];
        my $p=$args->[0];
        $heap->{rsvp}=$args->[1];
        # .... do lotsa stuff here
    }

    # eventually, we are finished
    sub finished
    {
        my($kernel, $heap, $return)=@_[KERNEL, HEAP, ARG0];
        $kernel->post(IKC=>'post', $heap->{rsvp}, $return);
    }

responded

    my $ret = $poe->responded( $state );
    my @ret = $poe->responded( $state );

Waits for $state from the remote kernel. $state must be a simple state name. Any requests from the remotre kernel for other states are rejected. A remote handler would respond by using the proxy sender.

call

    my $ret=$poe->call($specifier, $data);

This is the bad way to get information back from the a remote event. Follows the expected semantics from standard POE. It works better then post_respond, however, because it doesn't require you to change your interface or write a wrapper.

ping

    unless($poe->ping) {
        # connection is down!  connection is down!
    }

Find out if we are still connected to the remote kernel. This method will NOT try to reconnect to the remote server
