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 final int STATUS_NULL

This is the start and end state of every connection

另请参见：

getStatus(), 常量字段值

STATUS_AVAILABLE

static final int STATUS_AVAILABLE

The connection is available for use

方法详细信息

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
