AMQPCTableField Type
Represents an AMQP 0.9.1 table field.
Remarks
This type represents an AMQP 0.9.1 table field.
Fields
|
|
Name
String |
The table field's name.
This field specifies the table field's name. The name must be an ASCII string that:
- Starts with an ASCII letter, $, or $ character.
- Only contains ASCII letters, digits, underscores, $, and $ characters.
- Is unique among all sibling table field Names.
- Is no longer than 128 characters.
|
Value
String |
The table field's value.
This field specifies the table field's value.
|
ValueType
int |
The table field's value type.
This field specifies the table field's value type (and thus, the format of the data in the Value field). Acceptable value types are:
| | | Value Type | JSON Value Type | Description | Value Format | | fvtBoolean (0) | boolean | Boolean | "True" or "False" | | fvtByte (1) | byte | Byte | -128 to 127 | | fvtUbyte (2) | ubyte | Unsigned byte | 0 to 255 | | fvtShort (3) | short | Short | -32768 to 32767 | | fvtUshort (4) | ushort | Unsigned short | 0 to 65535 | | fvtInt (5) | int | Integer | -2147483648 to 2147483647 | | fvtUint (6) | uint | Unsigned integer | 0 to 4294967295 | | fvtLong (7) | long | Long | -9223372036854775808 to 9223372036854775807 | | fvtUlong (8) | ulong | Unsigned long | 0 to 18446744073709551615 | | fvtFloat (9) | float | Float | IEEE 754 32-bit floating point number | | fvtDouble (10) | double | Double | IEEE 754 64-bit floating point number | | fvtDecimal (11) | decimal | Decimal | Hex-encoded byte string | | fvtSstring (12) | sstring | Short string | UTF-8 string data, limited to 255 bytes; may not contain null bytes (\0) | | fvtString (13) | string | String | String data | | fvtArray (14) | array | Array | JSON array of type-value pairs | | fvtTimestamp (15) | timestamp | Timestamp | Number of milliseconds since the Unix epoch (January 1, 1970 00:00:00 UTC) | | fvtTable (16) | table | Table | JSON object containing name-type-value tuples | | fvtNull (17 - default) | null | Null | N/A (Value is ignored) |
Note: The fvtUlong (8) and fvtSstring (12) value types are not supported when the RabbitMQCompatible configuration setting is enabled.
For the fvtArray (14) value type, the Value should be specified as a JSON array of type-value pairs; for example:
[
{ "type": "int", "value": 23 },
{ "type": "int", "value": -52 },
{ "type": "int", "value": 153325 }
]
For the fvtTable (16) value type, the Value should be specified as a JSON object containing name-type-value tuples; for example:
{
{ "name": "Test1", "type": "long", "value": 12345678901234 },
{ "name": "Test2", "type": "boolean", "value": "false" },
{ "name": "Test3", "type": "string", "value": "This is a test." }
}
Notes regarding fvtArray (14) and fvtTable (16) type Values:
- All "type" fields in the JSON content must be set to one of the value types in the table above.
- For fvtTable (16) type Values, all "name" fields must adhere to the rules described by the Key documentation.
- Nesting and mixing multiple levels of arrays and tables in the JSON is allowed.
