 Methods

set(element: syside.ChainedFeatureReference.set.M, name: syside.NameID = ...) → syside.ChainedFeatureReference.set.M: try_set but instead raises ValueError if this reference cannot be modified.

try_set(element: syside.ChainedFeatureReference.try_set.M, name: syside.NameID = ...) → syside.ChainedFeatureReference.try_set.M | None: Try changing the referenced element. Returns None if this reference cannot be modified, otherwise returns element argument.

	`set_chain`		`try_set_chain` but instead raises `ValueError` if this reference cannot be modified.
	`try_set_chain`		Try changing the referenced `element` to a chain of `Features`. Returns `None` if this reference cannot be modified, otherwise returns a new owned `Feature` that chains all `Features` in order.

	`element`	`R`	Returns the referenced `Element`. This may return `None`, e.g. when reference resolution failed, although in most such cases a placeholder element will be returned instead.
	`modifiable`	`R`	Returns `True` if this reference can be modified, that is the owning `Relationship` is an owned member of a `Namespace`. Calling `set` methods when `modifiable == False` will raise `ValueError`.
