CheckMemberValid Method (GraphModel<NodeType,NodeKey>)

This predicate is true if adding a node to a group node would result in an invalid graph.

Syntax

protected virtual bool CheckMemberValid( 
   NodeType groupnodedata,
   NodeType membernodedata,
   bool ignoreexistingmembership
)

groupnodedata: the node data that is a group
membernodedata: a node data to be considered for adding to the group
ignoreexistingmembership: whether to ignore the membernodedata's existing group membership, because that member is being transferred out of its existing group

This returns false for membership that would break the tree structure of the model's graph of groups.
