ProxyConnection
```
public interface ConnectionInfoIF
extends Comparable
```
Provides information about an individual connection. You can get a collection of these from ProxoolFacade. You get back information about all the connections in a particular pool.
```
 String alias = "myPool";
 Iterator i = ProxoolFacade.getConnectionInfos(alias).iterator();
 while (i.hasNext()) {
  ConnectionInfoIF c = (ConnectionInfoIF)i.next();
   ...
 }

`static int`	`MARK_FOR_EXPIRY` The next time this connection is made available we should expire it.
`static int`	`MARK_FOR_USE` Default - treat as normal
`static int`	`STATUS_ACTIVE` The connection is in use
`static int`	`STATUS_AVAILABLE` The connection is available for use
`static int`	`STATUS_NULL` This is the start and end state of every connection
`static int`	`STATUS_OFFLINE` The connection is in use by the house keeping thread

  - MARK_FOR_USE
```
static final int MARK_FOR_USE
```
    Default - treat as normal
    
    另请参阅:
    
    getMark(), 常量字段值
  - MARK_FOR_EXPIRY
```
static final int MARK_FOR_EXPIRY
```
    The next time this connection is made available we should expire it.
    
    另请参阅:
    
    getMark(), 常量字段值
  - STATUS_NULL
```
static final int STATUS_NULL
```
    This is the start and end state of every connection
    
    另请参阅:
    
    getStatus(), 常量字段值
  - STATUS_AVAILABLE
```
static final int STATUS_AVAILABLE
```
    The connection is available for use
    
    另请参阅:
    
    getStatus(), 常量字段值
  - STATUS_ACTIVE
```
static final int STATUS_ACTIVE
```
    The connection is in use

  - getBirthTime
```
long getBirthTime()
```
    The time that this connection was created. The number of milliseconds since midnight, January 1, 1970 UTC.
  - getBirthDate
```
Date getBirthDate()
```
    Like getBirthTime() but in Date format
    
    返回:
    
    birthDate
  - getAge
```
long getAge()
```
    The age in millseconds since this connection was built
  - getId
```
long getId()
```
    A unique ID for this connection
  - getMark
```
int getMark()
```
    Sometimes we want do something to a connection but can't because it is still active and we don't want to disrupt its use. So we mark it instead and when it stops being active we can perform the necessary operation. The only thing we do at the moment is expire the connection (if it is too old for instance). And this will happen if the housekeeper decides it should but the connection is still active.
  - getStatus
```
int getStatus()
```
    The status of the connection. Can be either: null, available, active or offline.
  - getTimeLastStartActive
```
long getTimeLastStartActive()
```
    When this connection was last given out. The number of milliseconds since midnight, January 1, 1970 UTC.
  - getTimeLastStopActive
```
long getTimeLastStopActive()
```
    When this connection was last given back (or zero if it is still active). The number of milliseconds since midnight, January 1, 1970 UTC.
  - getRequester
```
String getRequester()
```
    The name of the thread that asked for this connection.
  - getProxyHashcode
```
String getProxyHashcode()
```
    The hashcode (in hex) of the ProxyConnection object. This uniquely identifies this proxy connection.
    
    返回:
    
    proxyHashcode
  - getDelegateHashcode
```
String getDelegateHashcode()
```
    The hashcode (in hex) of the delegate connection object. This uniquely identifies the underlying connection.
    
    返回:
    
    delegateHashcode
  - getDelegateUrl
```
String getDelegateUrl()
```
    The URL that this connection is using (the definition might have changed since this connection was built).
    
    返回:
    
    delegateUrl
  - getSqlCalls
```
String[] getSqlCalls()
```
    A log of the last SQL used on this connection. Only populated if ConnectionPoolDefinitionIF.isTrace() is enabled.
    
    返回:
    
    the most recent SQL to be used
