ArgumentValueType Property
The table property's value type.
Object Oriented Interface
public function getArgumentValueType($argumentindex); public function setArgumentValueType($argumentindex, $value);
Procedural Interface
ipworksmq_amqpclassic_get($res, 4 , $argumentindex); ipworksmq_amqpclassic_set($res, 4, $value , $argumentindex);
Default Value
17
Remarks
The table field's value type.
This property specifies the table field's value type (and thus, the format of the data in the ArgumentValue property). 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 (ArgumentValue 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 ArgumentValue 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 ArgumentValue 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 ArgumentValues:
- All "type" fields in the JSON content must be set to one of the value types in the table above.
- For fvtTable (16) type ArgumentValues, all "name" fields must adhere to the rules described by the ArgumentKey documentation.
- Nesting and mixing multiple levels of arrays and tables in the JSON is allowed.
The $argumentindex parameter specifies the index of the item in the array. The size of the array is controlled by the ArgumentCount property.
This property is not available at design time.
