Enum Constant Detail

EQUAL

public static final RelationalValidationOperator EQUAL

Equal.

UNEQUAL

public static final RelationalValidationOperator UNEQUAL

Unequal.

GREATER_THAN

public static final RelationalValidationOperator GREATER_THAN

Greater than.

GREATER_THAN_OR_EQUAL

public static final RelationalValidationOperator GREATER_THAN_OR_EQUAL

Greater than or equal.

LESS_THAN

public static final RelationalValidationOperator LESS_THAN

Method Detail

values

public static RelationalValidationOperator[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RelationalValidationOperator c : RelationalValidationOperator.values())
    System.out.println(c);

Returns:

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

valueOf

public static RelationalValidationOperator 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

validate

public abstract <T extends Comparable<? super T>> boolean validate(T left,
                                                                   T right)

Validates the left and right object against each other.

Type Parameters:

T - The Comparable type.

Parameters:

left - The value on the left of the relational operator.

right - The value on the right of the relational operator.

Returns:

True When validation succeeds, false when it fails.

Throws:

NullPointerException - When either left or right is null.

toString

public String toString()

Creates a String representation of this RelationalValidationOperator, consisting of the mathematical representation.

Overrides:

toString in class Enum<RelationalValidationOperator>

Returns:

The mathematical representation of this RelationalValidationOperator.
