class SequenceValueType

Bases: ValueType

The SequenceValueType corresponds to a sequence of values 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.
short_str()	Return the short string representation of the type.

Attributes

alias	An optional alias of the type.
is_list_type	Return whether the type is a list 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.
value_type	The value type of the sequence.

__init__(value_type, alias=None)

Initialize the sequence value type.

Parameters:

• value_type (ValueType) – The value type of the sequence.

• alias (str | None) –

__new__(**kwargs)

assignment_type()

Return the value type for assignment.

Return type:

ValueType

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()

Return the long string representation of the type.

Return type:

str

short_str()

Return the short string representation of the type.

Return type:

str

property alias: str | None

An optional alias of the type.

property is_list_type

Return whether the type is a list type.

property parent_type: TypeBase | None

The parent type of the type.

property parent_typename

Return the typename of the parent type.

property typename: str

The (full) typename of the type.

value_type: ValueType

The value type of the sequence.
