Constructor Details

HttpStreamOverFCGI

public HttpStreamOverFCGI(ServerFCGIConnection connection,
 ServerGenerator generator,
 HttpChannel httpChannel,
 int id)

Method Details

getHttpChannel

public HttpChannel getHttpChannel()

getId

public String getId()

Specified by:

getId in interface HttpStream

Returns:

an ID unique within the lifetime scope of the associated protocol connection. This may be a protocol ID (e.g. HTTP/2 stream ID) or it may be unrelated to the protocol.

onHeader

public void onHeader(HttpField field)

onHeaders

public void onHeaders()

read

public Content.Chunk read()

Description copied from interface: HttpStream

Reads a chunk of content, with the same semantic as Content.Source.read().

This method is called from the implementation of Request.read().

Specified by:

read in interface HttpStream

Returns:

a chunk of content, possibly with non-null Content.Chunk.getFailure() or null.

demand

public void demand()

Description copied from interface: HttpStream

Demands more content chunks to the underlying implementation.

This method is called from the implementation of Request.demand(Runnable) and when the demand can be satisfied the implementation must call HttpChannel.onContentAvailable(). If there is a problem meeting demand, then the implementation must call HttpChannel.onFailure(Throwable).

Specified by:

demand in interface HttpStream

See Also:

• HttpChannel.onContentAvailable()
• HttpChannel.onFailure(Throwable)

onContent

public void onContent(Content.Chunk chunk)

onComplete

public void onComplete()

prepareResponse

public void prepareResponse(HttpFields.Mutable headers)

Description copied from interface: HttpStream

Prepare the response headers with respect to the stream. Typically this may set headers related to protocol specific behaviour (e.g. Keep-Alive for HTTP/1.0 connections).

Specified by:

prepareResponse in interface HttpStream

Parameters:

headers - The headers to prepare.

send

public void send(MetaData.Request request,
 MetaData.Response response,
 boolean last,
 ByteBuffer byteBuffer,
 Callback callback)

Description copied from interface: HttpStream

Send response meta-data and/or data.

Specified by:

send in interface HttpStream

Parameters:

request - The request metadata for which the response should be sent.

response - The response metadata to be sent or null if the response is already committed by a previous call to send.

last - True if this will be the last call to send and the response can be completed.

byteBuffer - A buffer of content to send or null if no content.

callback - The callback to invoke when the send is completed successfully or in failure.

getIdleTimeout

public long getIdleTimeout()

Specified by:

getIdleTimeout in interface HttpStream

setIdleTimeout

public void setIdleTimeout(long idleTimeoutMs)

Specified by:

setIdleTimeout in interface HttpStream

isCommitted

public boolean isCommitted()

Specified by:

isCommitted in interface HttpStream

consumeAvailable

public Throwable consumeAvailable()

Specified by:

consumeAvailable in interface HttpStream

succeeded

public void succeeded()

Description copied from interface: Callback

Callback invoked when the operation completes.

Specified by:

succeeded in interface Callback

See Also:

• Callback.failed(Throwable)

failed

public void failed(Throwable x)

Description copied from interface: Callback

Callback invoked when the operation fails.

Specified by:

failed in interface Callback

Parameters:

x - the reason for the operation failure

onIdleTimeout

public boolean onIdleTimeout(TimeoutException timeout)

toString

public String toString()

Overrides:

toString in class Object
