James Taylor commented on PHOENIX-1030:
---------------------------------------

Brainstorming on names, perhaps inside of Expression
{code}
public enum Deterministic {ALWAYS, PER_ROW, PER_STATEMENT};
{code}

> Change Expression.isDeterministic() to return an ENUM with three values {DETERMINISTIC,
UNDETERMINISTIC_ROW, UNDETERMINISTIC_STMT}

> Change Expression.isDeterministic() to return an ENUM with three values
> DETERMINISTIC -  the expression returns the same output every time given the same input.
> UNDETERMINISTIC_ROW - the expression should be computed for every row
> UNDETERMINISTIC_STMT - the expression should be be computed for a given statement only
once
> See PHOENIX-1001
