class Value(*args, **kwargs)[source]

Bases: ClosedTerm

Abstract base class for values.

template_class: alias of ValueTemplate

variable_class: alias of ValueVariable

datatype_class: ClassVar[type[Datatype]]: Datatype class associated with this value class.

datatype: ClassVar[Datatype]: Datatype associated with this value class.

classmethod check(arg: Any, function: Callable[[...], Any] | str | None = None, name: str | None = None, position: int | None = None) → Self[source]

function – Function or function name.
name – Argument name.
position – Argument position.

Returns:

Object.

n3() → str[source]

object_class: alias of Value

class ValueVariable(name: str, variable_class: type[Variable] | type[Term] | None = None)[source]

Bases: Variable

Value variable.

Parameters:: name – Name.
