Method Detail

computeConcreteValue

protected void computeConcreteValue()

Description copied from class: LazyGroupElement

Computes the concrete value of the expression. Goal is to call setConcreteValue(). Implementations should call getConcreteValue() on dependent LazyGroupElements if needed. May be called multiple times (in several threads), but generally, best effort is applied to only call once. So if the value this computes is not constant (e.g., is random), you should apply synchronization here and make sure you're always returning a consistent value here.
