2.4.4.17.5 Literal Tokens

Token Type

Byte-Code

Token Data Encoding

Invalid token

0x00

Padding value.

Signed int8

0x01

1 QWORD, least significant byte first, for the value, 2's complement, -128 to +127.

1 BYTE for sign. (possible values for sign in the following table) .

1 BYTE for base. (possible values for base in the following table).

Signed int16

0x02

1 QWORD, least significant byte first, 2's complement, -32768 to +32767.

1 BYTE for sign.

1 BYTE for base.

Signed int32

0x03

1 QWORD, least significant byte first, 2's complement.

1 BYTE for sign.

1 BYTE for base.

Signed int64

0x04

1 QWORD, least significant byte first, 2's complement.

1 BYTE for sign.

1 BYTE for base.

Unicode String

0x10

1 DWORD for the length in bytes.

1 WORD for each Unicode character. Characters are stored LSB first. Strings are not null-terminated.

Octet String

0x18

Custom data is represented as a contiguous sequence of bytes.

1 DWORD for the length in bytes.

1 BYTE for each data octet.

Composite

0x50

1 DWORD that specifies the entire length in bytes of the entire set of elements.

List type--can be heterogeneous. Elements are stored in contiguous fashion according to the built-in data type storage rules.

SID

0x51

1 DWORD that specifies the entire length in bytes of the SID.

SID in binary representation (as specified in section 2.4.2.2.)

Tokens in the preceding table that contain a base MUST include a base code from the following table.

8

0x01

Octal

0x02

Decimal

16

0x03

Hexadecimal

Tokens in the preceding table that contain signs MUST include a sign code from the following table.

Relational operators interpret no sign (0x03) as positive.

Relational operators MUST use this to determine the sign of the literal during evaluation.

Sign

Description

+

0x01

Plus sign in condition.

-

0x02

Minus sign in condition.

None

0x03

No sign in condition.

Thus the decimal value -1 encoded as a signed int64 would have the following binary representation (byte code, QWORD, sign byte, base byte):

 0x04 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0x02 0x02
