Enum Constant Detail

EQUAL_TO

public static final ComparableFilter.Operator EQUAL_TO

The equal (==) operator.

NOT_EQUAL_TO

public static final ComparableFilter.Operator NOT_EQUAL_TO

The not-equal (!=, <>) operator.

GREATER_THAN

public static final ComparableFilter.Operator GREATER_THAN

The greater-than (>) operator.

GREATER_THAN_OR_EQUAL_TO

public static final ComparableFilter.Operator GREATER_THAN_OR_EQUAL_TO

The greater-than-or-equal (>=) operator.

LESS_THAN

public static final ComparableFilter.Operator LESS_THAN

Method Detail

values

public static ComparableFilter.Operator[] 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 (ComparableFilter.Operator c : ComparableFilter.Operator.values())
    System.out.println(c);

Returns:

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

valueOf

public static ComparableFilter.Operator 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

toString

public String toString()

Returns the String representation of this operator.

Overrides:

toString in class Enum<ComparableFilter.Operator>
