Enum Constant Detail

NULL

public static final Placeholder NULL

This might be useful to distinguish the case when a value resolver should return a value which should be interpreted as a null. Normally, a resolver returns null in case it's not capable of resolving the value.

Method Detail

values

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

Returns:

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

valueOf

public static Placeholder 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
