Detailed Description

A descriminated union that holds any scalar AMQP value.

The type field indicates the AMQP type of the value, and the union may be used to access the value for a given type.

Field Documentation

bool pn_atom_t::as_bool

Valid when type is PN_BOOL.

int8_t pn_atom_t::as_byte

Valid when type is PN_BYTE.

pn_bytes_t pn_atom_t::as_bytes

Valid when type is PN_BINARY or PN_STRING or PN_SYMBOL.

When the type is PN_STRING the field will point to utf8 encoded unicode. When the type is PN_SYMBOL, the field will point to 7-bit ASCII. In the latter two cases, the bytes pointed to are not necessarily null terminated.

pn_char_t pn_atom_t::as_char

Valid when type is PN_CHAR.

pn_decimal128_t pn_atom_t::as_decimal128

Valid when type is PN_DECIMAL128.

pn_decimal32_t pn_atom_t::as_decimal32

Valid when type is PN_DECIMAL32.

pn_decimal64_t pn_atom_t::as_decimal64

Valid when type is PN_DECIMAL64.

double pn_atom_t::as_double

Valid when type is PN_DOUBLE.

float pn_atom_t::as_float

Valid when type is PN_FLOAT.

int32_t pn_atom_t::as_int

Valid when type is PN_INT.

int64_t pn_atom_t::as_long

Valid when type is PN_LONG.

int16_t pn_atom_t::as_short

Valid when type is PN_SHORT.

pn_timestamp_t pn_atom_t::as_timestamp

Valid when type is PN_TIMESTAMP.

uint8_t pn_atom_t::as_ubyte

Valid when type is PN_UBYTE.

uint32_t pn_atom_t::as_uint

Valid when type is PN_UINT.

uint64_t pn_atom_t::as_ulong

Valid when type is PN_ULONG.

uint16_t pn_atom_t::as_ushort

Valid when type is PN_USHORT.

pn_uuid_t pn_atom_t::as_uuid

Valid when type is PN_UUID.

pn_type_t pn_atom_t::type

Indicates the type of value the atom is currently pointing to.

See pn_type_t for details on AMQP types.
