Method Detail

values

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

Returns:

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

valueOf

public static TransactionMode 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

getStatementString

public String getStatementString()

Use this method to get the correct format for use in a SQL statement. The SQL statement for setting the mode to read-only should for example be without the underscore: SET TRANSACTION READ ONLY

Returns:

a string representation of this TransactionMode that can be used in a SQL statement to set the transaction mode.

toString

public String toString()

Overrides:

toString in class Enum<TransactionMode>
