Expression

  • This content defines an arbitrary expression of an arbitrary type, where the response type is determined by its usage context.

  • The JSON representation includes values, a map of intermediate computation values, and result, indicating the final computed value among the values.

  • The values field in the JSON representation is a map of key-value pairs, where keys are strings and values are ValueNode objects forming an acyclic directed graph.

  • The result field in the JSON representation is a string that identifies the final result of the computation from the specified values.

Specifies an arbitrary expression, of an arbitrary type. The context in which it is used determines the type of the response.

Fields
values

map (key: string, value: object (ValueNode))

All intermediate values in the computation. The directed graph these form must be acyclic.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
result

string

Which of the ValueNodes in "values" is the final result of the computation.
