NAME

Net::MQTT::Constants − Module to export constants for MQTT protocol

VERSION

version 1.163170

SYNOPSIS

use Net::MQTT::Constants;

DESCRIPTION

Module to export constants for MQTT protocol.

FUNCTIONS"

"decode_remaining_length( $data, \$offset )"

Calculates the "remaining length" from the bytes in $data starting at the offset read from the scalar reference. The offset reference is subsequently incremented by the number of bytes processed.

encode_remaining_length( $length )

Calculates the "remaining length" bytes from the length, $length, and returns the packed bytes as a string.

"decode_byte( $data, \$offset )"

Returns a byte by unpacking it from $data starting at the offset read from the scalar reference. The offset reference is subsequently incremented by the number of bytes processed.

encode_byte( $byte )

Returns a packed byte.

"decode_short( $data, \$offset )"

Returns a short (two bytes) by unpacking it from $data starting at the offset read from the scalar reference. The offset reference is subsequently incremented by the number of bytes processed.

encode_short( $short )

Returns a packed short (two bytes).

"decode_string( $data, \$offset )"

Returns a string (short length followed by length bytes) by unpacking it from $data starting at the offset read from the scalar reference. The offset reference is subsequently incremented by the number of bytes processed.

encode_string( $string )

Returns a packed string (length as a short and then the bytes of the string).

qos_string( $qos_value )

Returns a string describing the given QoS value.

message_type_string( $message_type_value )

Returns a string describing the given "message_type" value.

dump_string( $data )

Returns a string representation of arbitrary data − as a string if it contains only printable characters or as a hex dump otherwise.

connect_return_code_string( $return_code_value )

Returns a string describing the given "connect_return_code" value.
