syside.OwnedMemberAccessor

class OwnedMemberAccessor

Bases: syside.MemberAccessor[syside.OwnedMemberAccessor.R, syside.OwnedMemberAccessor.M]

set_member_element(element: syside.M, name: syside.NameID = ...) → tuple[syside.R, syside.M]

Set a new owned member_element, ownership constraints apply. Replaces the previous member_element, which may be reused by the model. name_id has no effect since the element is always taken ownership of.

Returns a pair of (membership, member_element) where member_element is element.

set_member_element(element: syside.M | None, name: syside.NameID = ...) → tuple[syside.R, syside.M] | None

set_member_element overload that will remove the member element if element is None, otherwise the behaviour is the same.

set_member_element(arg: type[syside.M], /) → tuple[syside.R, syside.M]

Constructs a new empty member_element with the provided type. Replaces the previous member_element. Because a new element is always constructed, ownership constraints do not apply.

Returns a pair of (membership, member_element).

add_member_element() → tuple[syside.R, syside.M]

Constructs a new member_element with the default type if this member is empty, otherwise does nothing.

Returns a pair of (membership, member_element)

property membership: syside.R

The membership of this member if it is not empty.

property member_element: syside.M

The member_element of this member if it is not empty.

remove_member_element() → None

Remove the member_element leaving this member empty. Note that not all empty members are valid textual syntax. This does not check that the model is left in a valid state.

__bool__() → bool
