__getitem__(name)

Parameters:

name (str)

__init__(features, object_names, object_types=None, batch_dims=0, internals=None)

Initialize the state.

Parameters:

• features (Mapping[str, Any] | MultidimensionalArrayInterface | None) – the features of the state.

• object_types (Iterable[ObjectType] | None) – the types of the objects.

• object_names (Iterable[str] | Mapping[str, ObjectType]) – the names of the objects. If the object_names is a mapping, the object_types should be None.

• batch_dims (int) – the number of batchified dimensions.

• internals (Mapping[str, Any] | None) – the internals of the state.

__new__(**kwargs)

batch_set_value(feature_name, value)

Parameters:

• feature_name (str)

• value (Tensor | tuple | list)

Return type:

None

clone()

Return type:

NamedObjectTensorState

clone_internals()

Clone the internals.

extra_state_str_after()

Extra state string.

Return type:

str

extra_state_str_before()

Extra state string: add the objects.

Return type:

str

fast_set_value(feature_name, indices, value)

Parameters:

• feature_name (str)

• indices (Sequence[str])

• value (Any)

get_default_typename(name)

Get the typename of the object with the given name.

Parameters:

name (str)

Return type:

str

get_name(typename, index)

Get the name of the object with the given type and index.

Parameters:

• typename (str)

• index (int)

Return type:

str

get_nr_objects_by_type(typename)

Get the number of objects with the given type.

Parameters:

typename (str)

Return type:

int

get_objects_by_type(typename)

Get the names of the objects with the given type.

Parameters:

typename (str)

Return type:

List[str]

get_state_object_list(dtype, indices=None, names=None)

Get a list of object references with the given type and indices.

Parameters:

• dtype (ObjectType | str)

• indices (Sequence[int] | slice | None)

• names (Sequence[str] | None)

Return type:

StateObjectList

get_state_object_reference(dtype, index=None, name=None)

Get the object reference with the given type and index.

Parameters:

• dtype (ObjectType | str)

• index (int | None)

• name (str | None)

Return type:

StateObjectReference

get_typed_index(name, typename=None)

Get the typed index of the object with the given name. There is an additional typename argument to specify the type of the object. Because the same object can have multiple types (due to inheritence), the object can have multiple typed indices, one for each type. When the typename is not specified, the default type of the object is used (i.e., the most specific type).

Parameters:

• name (str) – the name of the object.

• typename (str | None) – the typename of the object. If not specified, the default type of the object is used (i.e. the most specific type).

Returns:

the typed index of the object.

Return type:

int

classmethod make_empty_state(domain, objects)

Parameters:

• domain (CrowDomain)

• objects (Dict[str, str])

summary_string()

Get a summary string of the state. The main difference between this and __str__ is that this function only formats the shape of intermediate tensors.

Return type:

str

property batch_dims: int

The number of batchified dimensions. For the basic State, it should be 0.

property features: TensorValueDict

property internals: Dict[str, Any]

Additional internal information about the state.

property nr_objects: int

The number of objects in the current state.
