org.osgi.service.transaction.control.TransactionStatus

All Implemented Interfaces:

Serializable, Comparable<TransactionStatus>

public enum TransactionStatus
extends Enum<TransactionStatus>

Method Detail

values

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

Returns:

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

valueOf
