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.
