Method Detail

values

public static ConfigurationPolicy[] values()

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

Returns:

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

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:
