Method Detail

values

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

Returns:

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