Enum JdbcConnectionFactory

java.lang.Object

java.lang.Enum<JdbcConnectionFactory>

org.apache.ctakes.dictionary.lookup2.util.JdbcConnectionFactory

All Implemented Interfaces:

Serializable, Comparable<JdbcConnectionFactory>

public enum JdbcConnectionFactory
extends Enum<JdbcConnectionFactory>

Some JDBC Connections can be reused, for instance by a Dictionary and Concept Factory. This Singleton keeps a map of JDBC URLs to open and reusable Connections

Method Detail

values

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

Returns:

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

valueOf

public static JdbcConnectionFactory 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

getInstance

public static JdbcConnectionFactory getInstance()

getConnection

public Connection getConnection(String jdbcDriver,
                                String jdbcUrl,
                                String jdbcUser,
                                String jdbcPass)
                         throws SQLException

Get an existing Connection or create and store a new one

Parameters:

jdbcDriver - -

jdbcUrl - -

jdbcUser - -

jdbcPass - -

Returns:

a previously opened or new Connection

Throws:

SQLException - if a JDBC Driver could not be created or registered, or if a Connection could not be made to the given jdbcUrl
