TupleVariable

relationalai.semantics.frontend.base

TupleVariable(items: Sequence[Value | Distinct])

Group multiple DSL values into a single tuple-like argument.

TupleVariable wraps a sequence of values so they can be passed as a single semantics.frontend.base.Value (most commonly to satisfy list-valued relationship fields declared with Field is_list=True).

During compilation, the wrapper is lowered to a tuple of its items.

Parameters

• items

  (Sequence[Value | Distinct]) - Values to group into a single argument.

Notes

Most users should not instantiate this class directly. It is primarily used by standard-library helpers (for example string/constraint utilities) and by internal compilation code.
