NAME
POE::Component::Generic::Object - A POE component that provides non-blocking access to a blocking object.
SYNOPSIS
use POE::Component::Generic;
my $generic = POE::Component::Generic->new(
package=>'Builder',
factories=>['build'] );
$generic->build( {event=>'created_foo'}, 'foo' );
# in the event "created_foo"
my( $resp, $foo ) = @_[ARG0, ARG1];
die $resp->{error} if $resp->{error}
my $objID = $foo->object_id; # Unique ID of the object
$foo->vibble( {}, @args ); # call a method on the object foo
$foo->yield( 'vibble', {}, @args ); # same as above
$foo->call( 'vibble', {}, @args ); # same as above
$generic->vibble( {obj=>$objID}, @args ); # same as aboveDESCRIPTION
POE::Component::Generic::Object is a proxy object for objects that were created by factory methods in the child process
METHODS
object_id
Returns a object ID for the object. This ID is unique to a given POE::Component::Generic component but might not be unique across POE::Component::Generic components.
session_id
Returns the session ID of the session that handles this object. Currently this corresponse to the parent POE::Component::Generic component, so it's not very useful. Eventually each proxy object will get its own session.
DESTROY
If you let the proxy object go out of scope, the object in the child will be destroyed.
THIS COULD BE SUPRISING.
Especially if you do something like:
my( $resp, $obj ) = @_[ ARG0, ARG1 ];
die $resp->{error} if $resp->{error};
$obj = $obj->object_id; # bang, no more sub-object.However, it does allow you to control when the object will be reaped.
METHOD CALLS
There are 3 ways of calling methods on the object.
All methods need a data hashref to specify the response event. This data hash is discussed in the "INPUT" section.
yield
This method provides an alternative object based means of asynchronisly calling methods on the object. First argument is the method to call, second is the data hashref, following arguments are sent as arguments to the resultant method call.
$poco->yield( open => { event => 'result' }, "localhost" );call
This method provides an alternative object based means of synchronisly calling methods on the object. First argument is the method to call, second is the data hashref, following arguments are sent as arguments to the resultant method call.
$poco->call( open => { event => 'result' }, "localhost" );Psuedo-method
All methods of the object can be called, but the first param must be the data hashref as noted below in the "INPUT" section below.
For example:
$poco->open( { event => 'opened' }, "localhost" );INPUT
Input works the same way as "INPUT" in POE::Component::Generic, except that the obj field defaults to the current object.
OUTPUT
Input works the same way as "OUTPUT" in POE::Component::Generic.
