ForeignKey[]	getForeignKeys() Get the foreign keys that reference this unique key.
KeyOwner	getKeyOwner() Get the KeyOwner.
boolean	isPrimaryKey() Determines if the UniqueKey is primary or not.
void	setColumns(Column[] columns) Sets the ordered list of columns this unique key consists of.
void	setPrimaryKey(boolean isPrimaryKey) Sets whether this is a primary key.
