    Returns true if expr can be evaluated using only the output of plan.

    Returns true if expr can be evaluated using only the output of plan. This method can be used to determine when it is acceptable to move expression evaluation within a query plan.

    For example consider a join between two relations R(a, b) and S(c, d).

    canEvaluate(EqualTo(a,b), R) returns true where as canEvaluate(EqualTo(a,c), R) returns false.
