Method Detail

values

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

Returns:

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

valueOf

public static EmbeddedDatabaseConnection 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

getDriverClassName

public String getDriverClassName()

Returns the driver class name.

Returns:

the driver class name

getType

public EmbeddedDatabaseType getType()

Returns the EmbeddedDatabaseType for the connection.

Returns:

the database type

getUrl

public String getUrl(String databaseName)

Returns the URL for the connection using the specified databaseName.

Parameters:

databaseName - the name of the database

Returns:

the connection URL

isEmbedded

public static boolean isEmbedded(String driverClass,
                                 String url)

Convenience method to determine if a given driver class name and url represent an embedded database type.

Parameters:

driverClass - the driver class

url - the jdbc url (can be null)

Returns:

true if the driver class and url refer to an embedded database

Since:

2.4.0

isEmbedded

public static boolean isEmbedded(DataSource dataSource)

Convenience method to determine if a given data source represents an embedded database type.

Parameters:

dataSource - the data source to interrogate

Returns:

true if the data source is one of the embedded types

get

public static EmbeddedDatabaseConnection get(ClassLoader classLoader)

Returns the most suitable EmbeddedDatabaseConnection for the given class loader.

Parameters:

classLoader - the class loader used to check for classes

Returns:

an EmbeddedDatabaseConnection or NONE.
