(4.2) use AbstractConnPool

@Deprecated
public abstract class AbstractConnPool
extends java.lang.Object

An abstract connection pool. It is used by the ThreadSafeClientConnManager. The abstract pool includes a poolLock, which is used to synchronize access to the internal pool datastructures. Don't use synchronized for that purpose!

                        throws java.lang.IllegalStateException

已过时。

抛出:

java.lang.IllegalStateException

getEntry

public final BasicPoolEntry getEntry(HttpRoute route,
                      java.lang.Object state,
                      long timeout,
                      java.util.concurrent.TimeUnit tunit)
                              throws ConnectionPoolTimeoutException,
                                     java.lang.InterruptedException

已过时。

Obtains a pool entry with a connection within the given timeout.

参数:

route - the route for which to get the connection

timeout - the timeout, 0 or negative for no timeout

tunit - the unit for the timeout, may be null only if there is no timeout

返回:

pool entry holding a connection for the route

抛出:

ConnectionPoolTimeoutException - if the timeout expired

java.lang.InterruptedException - if the calling thread was interrupted

requestPoolEntry

public abstract PoolEntryRequest requestPoolEntry(HttpRoute route,
                                java.lang.Object state)

已过时。

Returns a new PoolEntryRequest, from which a BasicPoolEntry can be obtained, or the request can be aborted.

             boolean reusable,
             long validDuration,
             java.util.concurrent.TimeUnit timeUnit)

已过时。

Returns an entry into the pool. The connection of the entry is expected to be in a suitable state, either open and re-usable, or closed. The pool will not make any attempt to determine whether it can be re-used or not.

参数:

entry - the entry for the connection to release

reusable - true if the entry is deemed reusable, false otherwise.

validDuration - The duration that the entry should remain free and reusable.

timeUnit - The unit of time the duration is measured in.

已过时。

deleteClosedConnections

public abstract void deleteClosedConnections()

已过时。

Deletes all entries for closed connections.

shutdown

public void shutdown()
