Method Detail

values

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

Returns:

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

valueOf

public static Comparator 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

fromString

public static Comparator fromString(String str)

Create a comparator from a string

Parameters:

str - the string representation

Returns:

the equivalent comparator

getInverse

public Comparator getInverse()

Inverts the operator

Returns:

the inverted operator

toString

public String toString()

Returns the string representation

Overrides:

toString in class Enum<Comparator>

Returns:

the string representation
