Method Detail

values

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

Returns:

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

valueOf

public static TransactionIsolationLevel 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

fromFieldValue

public static TransactionIsolationLevel fromFieldValue(int fieldValue)

Returns the enum constant of this type with the specified transaction isolation level.

Parameters:

fieldValue - the transaction isolation level

Returns:

the enum constant with the specified transaction isolation level

fromConnection

public static TransactionIsolationLevel fromConnection(Connection connection)
                                                throws SQLException

Returns the enum constant of this type with the specified connection's current transaction isolation level.

Parameters:

connection - the connection

Returns:

the enum constant with the specified connection's current transaction isolation level

Throws:

SQLException - if a database access error occurs or this method is called on a closed connection

Connection.getTransactionIsolation()

fieldValues

public static Integer[] fieldValues()

Returns an array containing the field values of this enum type.

Returns:

an array containing the field values of this enum type.

getFieldValue

public Integer getFieldValue()

Description copied from interface: FieldEnum

Returns field value.

Specified by:

getFieldValue in interface FieldEnum<TransactionIsolationLevel,Integer>

Returns:

field value.

set

public void set(Connection connection)
         throws SQLException

Attempts to change the transaction isolation level for given connection to this constant's field value.

Parameters:

connection - the connection

Throws:

SQLException - if a database access error occurs, this method is called on a closed connection
