All Implemented Interfaces:

Closeable, Flushable

Direct Known Subclasses:

AsyncHTTPConduit.AsyncWrappedOutputStream

Enclosing class:

HTTPConduit

protected abstract class HTTPConduit.WrappedOutputStream
extends AbstractThresholdOutputStream

Wrapper output stream responsible for flushing headers and handling the incoming HTTP-level response (not necessarily the MEP response).

cachingForRetransmission

protected boolean cachingForRetransmission

This boolean is true if the request must be cached.

chunking

protected final boolean chunking

If we are going to be chunking, we won't flush till close which causes new chunks, small network packets, etc..

cachedStream

protected CacheAndWriteOutputStream cachedStream

This field contains the output stream with which we cache the request. It maybe null if we are not caching.

outMessage

protected Message outMessage

conduitName

protected String conduitName

url

protected URI url

handleRetransmits

processRetransmit

protected boolean processRetransmit()
                             throws IOException

This function processes any retransmits at the direction of redirections or "unauthorized" responses.

Returns:

true if there was a retransmit

Throws:

IOException

authorizationRetransmit

protected boolean authorizationRetransmit()
                                   throws IOException

This method performs a retransmit for authorization information.

Parameters:

connection - The currently active connection.

message - The outbound message.

cachedStream - The cached request.

Returns:

A new connection if retransmitted. If not retransmitted then this method returns the same connection.

Throws:

IOException

handleResponse

protected void handleResponse()
                       throws IOException

This procedure is called on the close of the output stream so we are ready to handle the response from the connection. We may retransmit until we finally get a response.

Throws:

IOException

protected void handleResponseInternal()
                               throws IOException

Throws:

Throws:

IOException

makeTrustDecision

protected void makeTrustDecision()
                          throws IOException

This call must take place before anything is written to the URLConnection. The URLConnection.connect() will be called in order to get the connection information. This method is invoked just after setURLRequestHeaders() from the WrappedOutputStream before it writes data to the URLConnection. If trust cannot be established the Trust Decider implemenation throws an IOException.

Parameters:

message - The message being sent.

Throws:

IOException - This exception is thrown if trust cannot be established by the configured MessageTrustDecider.
