```
public static ConnectionUrl.Type[] 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 (ConnectionUrl.Type c : ConnectionUrl.Type.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ConnectionUrl.Type 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

                                           int n)
```
    Returns the ConnectionUrl.Type corresponding to the given scheme and number of hosts, if any. Otherwise throws an UnsupportedConnectionStringException. Calling this method with the argument n lower than 0 skips the hosts cardinality validation.
    
    Parameters:
    
    scheme - one of supported schemes
    
    n - the number of hosts in the database URL
    
    Returns:
    
    the ConnectionUrl.Type corresponding to the given protocol and number of hosts
  - getConnectionUrlInstance
```
public static ConnectionUrl getConnectionUrlInstance(ConnectionUrlParser parser,
                                                     Properties info)
```
    Instantiates a class that implements the right type of connection URLs for the given ConnectionUrlParser.
    
    Parameters:
    
    parser - the ConnectionUrlParser containing the URL components.
    
    info - a connection properties map to add to the ConnectionUrl structure.
    
    Returns:
    
    an instance of ConnectionUrl.
  - isSupported
```
public static boolean isSupported(String scheme)
```
    Checks if the given scheme corresponds to one of the connection types the driver supports.
    
    Parameters:
    
    scheme - scheme part from connection string, like "jdbc:mysql:"
    
    Returns:
    
    true if the given scheme is supported by driver
  - getImplementingInstance
```
private ConnectionUrl getImplementingInstance(ConnectionUrlParser parser,
                                              Properties info)
```
    Instantiates a class that implements this type of connection URLs with the given arguments.
    
    Parameters:
    
    parser - the ConnectionUrlParser containing the URL components.
    
    info - a connection properties map to add to the ConnectionUrl structure.
    
    Returns:
    
    an instance of ConnectionUrl.
