java.lang.Enum<IdentityFunction>

org.wildfly.clustering.marshalling.spi.IdentityFunction

All Implemented Interfaces:

Serializable, Comparable<IdentityFunction>, Function<Object,Object>

public enum IdentityFunction
extends Enum<IdentityFunction>
implements Function<Object,Object>

Behaves the same as Function.identity(), where the return type is a superclass of the function parameter.

Method Detail

values

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

Returns:

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

valueOf

public static IdentityFunction 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

apply

public Object apply(Object value)

Specified by:

apply in interface Function<Object,Object>

getInstance

public static <T extends R,R> Function<T,R> getInstance()

Returns a function that returns its parameter.

Type Parameters:

T - the parameter type

R - the return type

Returns:

a function that return its parameter
