NAME
GDPR::IAB::TCFv2::BitUtils - utilities functions to manage bits
SYNOPSIS use GDPR::IAB::TCFv2::BitUtils qw<get_uint16>;
my $data = unpack "B*", decode_base64url('tcf v2 consent string base64 encoded');
my $max_vendor_id_consent = get_uint16($data, 213);FUNCTIONS
is_set
Receive two parameters: data and bit offset.
Will return true if the bit present on bit offset is 1.
my $is_service_specific = is_set( $data, 138 );get_uint6
Receive two parameters: data and bit offset.
Will fetch 6 bits from data since bit offset and convert it an unsigned int.
my $version = get_uint6( $data, 0 );get_char6
Similar to GDPR::IAB::TCFv2::BitUtils::get_uint6 but perform increment the value with the ascii value of "A" letter and convert to a character.
get_char6_sequence
Receives the data, bit offset and sequence size n.
Returns a string of size n by concantenating GDPR::IAB::TCFv2::BitUtils::get_char6 calls.
my $consent_language = get_char6_sequence($data, 108, 2) # returns two letter country encoded as ISO_639-1 get_uint12
Receives the data and bit offset.
Will fetch 12 bits from data since bit offset and convert it an unsigned int (short).
my $cmp_id = get_uint12( $data, 78 );get_uint16
Receives the data and bit offset.
Will fetch 16 bits from data since bit offset and convert it an unsigned int (short).
my $max_vendor_id_consent = get_uint16( $data, 213 );get_uint36
Receives the data and bit offset.
Will fetch 36 bits from data since bit offset and convert it an unsigned int (long).
my $deciseconds = get_uint36( $data, 6 );
my $created = $deciseconds/2;
