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

Bit::MorseSignals::Emitter.

Carp (standard since perl 5), POSIX (idem) and Time::HiRes (since perl 5.7.3) are required.
