Protected Friend Overridable Function IsAddableRoleForElement (element As ModelElement, role As DomainRoleInfo) As Boolean

Parameters

element: ModelElement

The ModelElement into which a new child element would be merged

role: DomainRoleInfo

DomainRoleInfo describing the role

Returns

Boolean

True if the role is a candidate for addition, else false

Remarks

By default only non-abstract embedded elements are addable, with the exception of the extensions. Can be overridden, but it is not recommended to include relationships that are not embeddings, as the explorer makes a general assumption that it is only adding through embeddings and its behaviour is undefined if this is not the case
