IllegalStateException

getEntry

public final BasicPoolEntry getEntry(HttpRoute route,
                                     Object state,
                                     long timeout,
                                     TimeUnit timeUnit)

                                     InterruptedException

Deprecated.

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

Parameters:

route - the route for which to get the connection

state - the state

timeout - the timeout, 0 or negative for no timeout

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

Returns:

pool entry holding a connection for the route

Throws:

ConnectionPoolTimeoutException - if the timeout expired

InterruptedException - if the calling thread was interrupted

requestPoolEntry

public abstract PoolEntryRequest requestPoolEntry(HttpRoute route,
                                                  Object state)

Deprecated.

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

Parameters:

route - the route

state - the state

Returns:

the entry request

freeEntry

public abstract void freeEntry(BasicPoolEntry entry,
                               boolean reusable,
                               long validDuration,
                               TimeUnit timeUnit)

Deprecated.

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.

Parameters:

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.

handleReference

public void handleReference(Reference<?> ref)

Deprecated.

closeIdleConnections

public void closeIdleConnections(long idletime,
                                 TimeUnit timeUnit)

Deprecated.

Closes idle connections.

Parameters:

idletime - the time the connections should have been idle in order to be closed now

timeUnit - the unit for the idletime

closeExpiredConnections

public void closeExpiredConnections()

Deprecated.

deleteClosedConnections

public abstract void deleteClosedConnections()

Deprecated.

Deletes all entries for closed connections.

shutdown

public void shutdown()

Deprecated.

Shuts down this pool and all associated resources. Overriding methods MUST call the implementation here!
