SYNOPSIS
use POE;
use POE::Component::IKC::Specifier;
$state=specifier_parse('poe://*/timeserver/connect');
print 'The foreign state is '.specifier_name($state);
DESCRIPTION
This is a helper module that encapsulates POE IKC specifiers. An IKC specifier is a way of designating either a kernel, a session or a state within a IKC cluster.IKC specifiers have the folloing format :
poe:://kernel/session/state
kernel may a kernel name, a kernel ID, blank (for local kernel), a '*' (all known foreign kernels) or host:port (not currently supported).
session may be any session alias that has been published by the foreign kernel.
state is a state that has been published by a foreign session.
Examples :
- "poe://Pulse/timeserver/connect"
- State 'connect' in session 'timeserver' on kernel 'Pulse'.
- "poe:/timeserver/connect"
- State 'connect' in session 'timeserver' on the local kernel.
- "poe://*/timeserver/connect"
- State 'connect' in session 'timeserver' on any known foreign kernel.
- "poe://Billy/bob/"
- Session 'bob' on foreign kernel 'Billy'.
EXPORTED FUNCTIONS
specifier_parse($spec)
Turn a specifier into the internal representation (hash ref). Returns undef() if the specifier wasn't valid.
print Dumper specifer_parse('poe://Pulse/timeserver/time');
would print
$VAR1 = { kernel => 'Pulse', session => 'timeserver', state => 'time', };
Note : the internal representation might very well change some day.
specifier_name($spec)
Turns a specifier into a string.BUGS
