Attributes
All 2 declared on Instruction. Cardinality in amber is required.
| Name | Type | Card. | Description |
|---|---|---|---|
| primitiveInstruction | PrimitiveInstruction | 0..1 | Specifies the primitive instructions that will be used to call primitive event functions. |
| before | TradeState | 0..1 | Specifies the trade state that will be acted on by the primitive event functions. |
Conditions
Validation rules the model enforces on this type, in Rune. An instance that breaks one of these is invalid CDM, whatever produced it.
ExclusiveSplitPrimitive Condition
A split primitive is exclusive and cannot be combined with other primitives. Instead, the primitive instructions to be applied to each branch of the split must be specified as breakdowns in the split instruction itself.
if primitiveInstruction -> split exists
then primitiveInstruction -> split only exists NewTrade Condition
There must be no before trade state if the primitive instructions contain an execution, and vice versa. An instruction only handles 1 trade at a time.
(if primitiveInstruction -> execution exists then before is absent else True)
and (if before is absent then primitiveInstruction -> execution exists else True)Referenced by
1 type holds an Instruction as an attribute.
Functions
Model functions that produce or consume this type. These are the CDM's own behaviour — the logic a correct implementation has to match.
| Function | Role | Description |
|---|---|---|
| Create_PairOffInstruction | returns | Creates a set of instructions to pair-off a set of trades based on a pair reference. A package component is created based on that pair reference and the list of identifiers for the underlying trades. That package component is then added onto the execution details of every underlying trade. The existing trades are not terminated. |
| Create_BusinessEvent | takes | Creates a business event from instructions containing primitive instructions and optionally a trade state. |
