public interface LogicalConnection
```
Models the logical notion of a JDBC Connection. We may release/re-acquire physical JDBC connections under the covers, but this logically represents the overall access to the JDBC Connection.

方法概要

所有方法实例方法抽象方法
修饰符和类型	方法	说明
`Connection`	`close()`	Closes the JdbcSession, making it inactive and forcing release of any held resources
`ResourceRegistry`	`getResourceRegistry()`	Provides access to the registry of JDBC resources associated with this LogicalConnection.
`boolean`	`isOpen()`	Is this (logical) JDBC Connection still open/active.
`boolean`	`isPhysicallyConnected()`	Is this JdbcSession currently physically connected (meaning does it currently hold a JDBC Connection)?

- 方法详细资料
  - isOpen
```
boolean isOpen()
```
    Is this (logical) JDBC Connection still open/active. In other words, has close() not been called yet?
    
    返回:
    
    true if still open (close() has not been called yet); false if not open (close() has been called).
  - close
```
Connection close()
```
    Closes the JdbcSession, making it inactive and forcing release of any held resources
    
    返回:
    
    Legacy :( Returns the JDBC Connection *if* the user passed in a Connection originally.
  - isPhysicallyConnected
```
boolean isPhysicallyConnected()
```
    Is this JdbcSession currently physically connected (meaning does it currently hold a JDBC Connection)?
    
    返回:
    
    true if the JdbcSession currently hold a JDBC Connection; false if it does not.
  - getResourceRegistry
```
ResourceRegistry getResourceRegistry()
```
    Provides access to the registry of JDBC resources associated with this LogicalConnection.
    
    返回:
    
    The JDBC resource registry.
    
    抛出:
    
    ResourceClosedException - if the LogicalConnection is closed
