Enum Constant Details

UPDATED

public static final VariableStateResult UPDATED

The possible values of the variable were updated.

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 6.

FAILED

public static final VariableStateResult FAILED

Applying the restriction would leave the variable 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.

NO_CHANGE

public static final VariableStateResult NO_CHANGE

The variable already conformed to the restriction.

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 8.
