↳ | org.apache.http.nio.protocol.ThrottlingHttpServiceHandler |
Service protocol handler implementation that provide compatibility with
the blocking I/O by utilizing shared content buffers and a fairly small pool
of worker threads. The throttling protocol handler allocates input / output
buffers of a constant length upon initialization and controls the rate of
I/O events in order to ensure those content buffers do not ever get
overflown. This helps ensure nearly constant memory footprint for HTTP
connections and avoid the out of memory condition while streaming content
in and out. The handle(HttpRequest, HttpResponse, HttpContext)
method will fire immediately when a message is received. The protocol handler
delegate the task of processing requests and generating response content to
an Executor
, which is expected to perform those tasks using
dedicated worker threads in order to avoid blocking the I/O thread.

Triggered when the underlying channel is ready for reading a new portion of the request entity through the corresponding content decoder.
If the content consumer is unable to process the incoming content, input event notifications can be temporarily suspended usingIOControl
interface.conn | HTTP connection that can produce a new portion of the incoming request content. |
---|---|
decoder | The content decoder to use to read content. |
Triggered when the underlying channel is ready for writing a next portion of the response entity through the corresponding content encoder.
If the content producer is unable to generate the outgoing content, output event notifications can be temporarily suspended usingIOControl
interface.conn | HTTP connection that can accommodate a new portion of the outgoing response content. |
---|---|
encoder | The content encoder to use to write content. |
Triggered when a new HTTP request is received. The connection passed as a parameter to this method is guaranteed to return a valid HTTP request object.
If the request received encloses a request entity this method will be followed a series ofinputReady(NHttpServerConnection, ContentDecoder)
calls
to transfer the request content.conn | HTTP connection that contains a new HTTP request |
---|
Triggered when the connection is ready to accept a new HTTP response. The protocol handler does not have to submit a response if it is not ready.
conn | HTTP connection that contains an HTTP response |
---|
Triggered when no input is detected on this connection over the maximum period of inactivity.
conn | HTTP connection that caused timeout condition. |
