 Methods

__bool__() → bool

extract_member_element() → syside.M

Extract 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.

Note that it is up to the user to ensure that the returned orphan element is not leaked.

Raises ValueError if member is 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.

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

Set a new member_element. element will only be referenced if the membership is Membership, otherwise ownership constraints apply. Replaces the previous member_element, which may be reused by the model if it was owned.

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.
