Functions | |
| errorCode | decodeNBitUnsignedInteger (EXIStream *strm, unsigned char n, unsigned int *int_val) |
| Decode EXI n-bit Unsigned Integer Decodes and returns an n-bit unsigned integer. More... | |
| errorCode | decodeBoolean (EXIStream *strm, boolean *bool_val) |
| Decode EXI Boolean Decode a single boolean value. More... | |
| errorCode | decodeUnsignedInteger (EXIStream *strm, UnsignedInteger *int_val) |
| Decode EXI Unsigned Integer type Decode an arbitrary precision non negative integer using a sequence of octets. More... | |
| errorCode | decodeString (EXIStream *strm, String *string_val) |
| Decode EXI String type Decode a string as a length-prefixed sequence of UCS codepoints, each of which is encoded as an integer. More... | |
| errorCode | decodeStringOnly (EXIStream *strm, Index str_length, String *string_val) |
| Decode String with the length of the String specified This function is used for Partitions Optimized for Frequent use of String Literals when there is a local name miss => the Length part is read first. More... | |
| errorCode | decodeBinary (EXIStream *strm, char **binary_val, Index *nbytes) |
| Decode EXI Binary type Decode a binary value as a length-prefixed sequence of octets. More... | |
| errorCode | decodeIntegerValue (EXIStream *strm, Integer *sint_val) |
| Decode EXI (signed) Integer type Decode an arbitrary precision integer using a sign bit followed by a sequence of octets. More... | |
| errorCode | decodeDecimalValue (EXIStream *strm, Decimal *dec_val) |
| Decode EXI Decimal type Decode a decimal represented as a Boolean sign followed by two Unsigned Integers. More... | |
| errorCode | decodeFloatValue (EXIStream *strm, Float *fl_val) |
| Decode EXI Float type Decode a Float represented as two consecutive Integers. More... | |
| errorCode | decodeDateTimeValue (EXIStream *strm, EXIType dtType, EXIPDateTime *dt_val) |
| Decode DateTime type Included Components: Year, MonthDay, Time, presence, [FractionalSecs], presence, [TimeZone]. More... | |

| EXIType | dtType, | ||
| EXIPDateTime * | dt_val | ||
| ) |
| [in] | strm | EXI stream of bits |
| [in] | dtType | the exact type of the dateTime value. Should be one of VALUE_TYPE_DATE_TIME, VALUE_TYPE_YEAR, VALUE_TYPE_DATE, VALUE_TYPE_MONTH, VALUE_TYPE_TIME |
| [out] | dt_val | decoded dateTime value as EXIPDateTime |
Definition at line 245 of file streamDecode.c.
A sign value of zero (0) is used to represent positive Decimal values and a sign value of one (1) is used to represent negative Decimal values The first Integer represents the integral portion of the Decimal value. The second positive integer represents the fractional portion of the decimal with the digits in reverse order to preserve leading zeros.
| [in] | strm | EXI stream of bits |
| [out] | dec_val | decoded decimal value |
Definition at line 169 of file streamDecode.c.
The first Integer represents the mantissa of the floating point number and the second Integer represents the 10-based exponent of the floating point number

| [out] | fl_val | decoded float value as double |
Definition at line 215 of file streamDecode.c.
The most significant bit of the last octet is set to zero to indicate sequence termination. Only seven bits per octet are used to store the integer's value.
