NAME
IPC::MorseSignals::Emitter - Base class for IPC::MorseSignals emitters.
VERSION
Version 0.16
SYNOPSIS
use IPC::MorseSignals::Emitter;
my $deuce = IPC::MorseSignals::Emitter->new(speed => 1024);
$deuce->post('HLAGH') for 1 .. 3;
$deuce->send($pid);
DESCRIPTION
This module sends messages processed by an underlying Bit::MorseSignal emitter to another process as a sequence of SIGUSR1
(for bits 0) and SIGUSR2
(for 1) signals.
METHODS
new < delay => $seconds, speed => $bauds, %bme_options >
Creates a new emitter object. delay
specifies the delay between two sends, in seconds, while speed
is the number of bits sent per second. The delay value has priority over the speed. Default delay is 1 second. Extra arguments are passed to "new" in Bit::MorseSignals::Emitter.
send $pid
Sends messages enqueued with "post" in Bit::MorseSignals::Emitter to the process $pid
(or to all the @$pid
if $pid
is an array reference, in which case duplicated targets are stripped off).
delay < $seconds >
Returns the current delay in seconds, or set it if an argument is provided.
speed < $bauds >
Returns the current speed in bauds, or set it if an argument is provided.
IPC::MorseSignals::Emitter objects also inherit methods from Bit::MorseSignals::Emitter.
EXPORT
An object module shouldn't export any function, and so does this one.
DEPENDENCIES
Carp (standard since perl 5), POSIX (idem) and Time::HiRes (since perl 5.7.3) are required.
