Method Detail

values

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

Returns:

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

valueOf

public static JdbcUtils 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

openConnection

public static Connection openConnection(DataSource dataSource,
                                        int connectRetries,
                                        int connectRetriesInterval,
                                        DatabaseTypeRegister databaseTypeRegister)
                                 throws MigrateDbException

Opens a new connection from dataSource.

Parameters:

dataSource - The dataSource to obtain the connection from.

connectRetries - The maximum number of retries when attempting to connect to the database.

connectRetriesInterval - The maximum time between retries in seconds

Returns:

The new connection.

Throws:

MigrateDbException - if the connection could not be opened.

Quietly closes this connection. This method never throws an exception even if closing the connection fails.

closeStatement

public static void closeStatement(Statement statement)

Quietly closes this statement. This method never throws an exception even if closing the connection fails.

closeResultSet

public static void closeResultSet(ResultSet resultSet)

Quietly closes this resultSet. This method never throws an exception even if closing the connection fails.
