Initializes this connection object with SessionInputBuffer and SessionOutputBuffer instances to be used for sending and receiving data. These session buffers can be bound to any arbitrary physical output medium.

This method will invoke createHttpResponseFactory(), createRequestWriter(SessionOutputBuffer, HttpParams) and createResponseParser(SessionInputBuffer, HttpResponseFactory, HttpParams) methods to initialize HTTP request writer and response parser for this connection.

已过时。

isStale

public boolean isStale()

已过时。

从接口复制的说明: HttpConnection

Checks whether this connection has gone down. Network connections may get closed during some time of inactivity for several reasons. The next time a read is attempted on such a connection it will throw an IOException. This method tries to alleviate this inconvenience by trying to find out if a connection is still usable. Implementations may do that by attempting a read with a very small timeout. Thus this method may block for a small amount of time before returning a result. It is therefore an expensive operation.

指定者:

isStale 在接口中 HttpConnection

返回:

true if attempts to use this connection are likely to succeed, or false if they are likely to fail and this connection should be closed

getMetrics

public HttpConnectionMetrics getMetrics()

已过时。

从接口复制的说明: HttpConnection

Returns a collection of connection metrics.

指定者:

getMetrics 在接口中 HttpConnection

返回:

HttpConnectionMetrics
