class SDeicticAssignExpression

Bases: SVariableAssignmentExpression

The representation of a deictic assignment expression.

Methods

ground(variable_dict[, state])	Return a new expression with all variables grounded according to the given variable dictionary.
iter_effect_predicates()	Iterate over the effect predicate names in the expression.
iter_precondition_predicates()	Iterate over the precondition predicate names in the expression.

Attributes

variable	The deictic expression.
expression	The inner assignment expression.

__init__(variable, expression)

Initialize a deictic assignment expression.

Parameters:

• variable (Variable) – the deictic variable.

• expression (SVariableAssignmentExpression) – the inner assignment expression.

__new__(**kwargs)

ground(variable_dict, state=None)

• state (SState | Set[str] | None)

iter_effect_predicates()

Iterate over the effect predicate names in the expression.

Return type:

Iterable[str]

iter_precondition_predicates()
