    按照声明该枚举类型的常量的顺序, 返回包含这些常量的数组。该方法可用于迭代常量, 如下所示:
    for (ConnectionUrl.Type c : ConnectionUrl.Type.values()) System.out.println(c);
    返回:

  - valueOf
```
public static ConnectionUrl.Type valueOf(String name)
```
    返回带有指定名称的该类型的枚举常量。字符串必须与用于声明该类型的枚举常量的标识符完全匹配。(不允许有多余的空格字符。)
    
    参数:
    
    name - 要返回的枚举常量的名称。
    
    返回:
    
    返回带有指定名称的枚举常量

```
    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.
    
    参数:
    
    scheme - one of supported schemes
    
    n - the number of hosts in the database URL
    
    返回:
    
    the ConnectionUrl.Type corresponding to the given protocol and number of hosts
  - getConnectionUrlInstance

```
    Instantiates a class that implements the right type of connection URLs for the given ConnectionUrlParser.
    
    参数:
    
    parser - the ConnectionUrlParser containing the URL components.
    
    info - a connection properties map to add to the ConnectionUrl structure.
    
    返回:
    
    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.
    
    参数:
    
    scheme - scheme part from connection string, like "jdbc:mysql:"
    
    返回:
    
    true if the given scheme is supported by driver
