Enum Constant Details

MATCHED

public static final ConstraintResult MATCHED

The constraint was satisfied - it has been proven to be true.

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

FAILED

public static final ConstraintResult FAILED

The constraint cannot be satisfied - it has been proven to be false.

e.g. Given X has a minimum value of 4 and a maximum value of 7, this result would be returned when attempting to satisfy the constraint "Xinvalid input: '<'4".

UNRESOLVED

public static final ConstraintResult UNRESOLVED

It was not possible to determine if the constraint is satisfied or not.

e.g. Given X has a minimum value of 4 and a maximum value of 7, this result would be returned when attempting to satisfy the constraint "Xinvalid input: '<'6".

Method Details

values

public static ConstraintResult[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ConstraintResult valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
