VALID

public static final ExpressionResult VALID

The expression conforms to the given restriction.

Example a) Given X has a minimum value of 4 and a maximum value of 7, this result would be returned when attempting to set the maximum value to 6.

Example b) Given X has a minimum value of 4 and a maximum value of 7, this result would be returned when attempting to set the maximum value to 8.

INVALID

public static final ExpressionResult INVALID

Applying the restriction would leave the expression with no possible values.

e.g. Given X has a minimum value of 4 and a maximum value of 7, this result would be returned when attempting to set the maximum value to 3.
