class ValueType[source]#

The ValueType corresponds to a value of a certain type.

Methods

`assignment_type`()	Return the value type for assignment.
`downcast_compatible`(other[, ...])	Check if the type is downcast-compatible with the other type; that is, if this type is a subtype of the other type.
`long_str`()	Return the long string representation of the type.
`set_parent_type`(parent_type)
`short_str`()	Return the short string representation of the type.
`unwrap_alias`()

Attributes

`alias`	An optional alias of the type.
`base_typename`	Return the typename of the base type.
`element_type`	The element type of the type.
`is_batched_list_type`	Return whether the type is a multidimensional list type.
`is_list_type`	Return whether the type is a list type.
`is_object_type`	Return whether the type is an object type.
`is_pyobj_value_type`	Return whether the type is a Python object value type.
`is_scalar_value_type`
`is_sequence_type`	Return whether the type is a sequence type.
`is_tensor_value_type`	Return whether the type is a tensor value type.
`is_tuple_type`	Return whether the type is a tuple type.
`is_uniform_sequence_type`
`is_value_type`	Return whether the type is a value type.
`is_vector_value_type`
`is_wrapped_value_type`
`parent_type`	The parent type of the type.
`parent_typename`	Return the typename of the parent type.
`typename`	The (full) typename of the type.

__init__(typename, alias=None, parent_type=None)#

Initialize the type.

Parameters:

assignment_type()#

Return the value type for assignment.

downcast_compatible(other, allow_self_list=False, allow_list=False)#

Check if the type is downcast-compatible with the other type; that is, if this type is a subtype of the other type.

Parameters:

other (TypeBase) – the other type.
allow_self_list (bool) – if True, this type can be a list type derived from the other type.
allow_list (bool) – if True, the other type can be a list type derived from the type.

Return type:

bool

long_str()[source]#

Return the long string representation of the type.

set_parent_type(parent_type)#

short_str()#

Return the short string representation of the type.
