CachedAttribute

class CachedAttribute[T, U] extends Attribute[T, U] with IdMemoised[T, Option[U]]

An attribute of a node type T with value of type U, supported by a memo table and circularity test. The value of the attribute is computed by the function f. The result is memoised so that it is only evaluated once. f should not itself require the value of this attribute. If it does, a circularity error is reported by throwing an IllegalStateException.
