writeResponseStatusAndHeaders
Description copied from interface:ContainerResponseWriter
Write the status and headers of the response and return an output stream for the web application to write the entity of the response.If the response content length is declared to be greater or equal to 0, it means that the content length in bytes of the entity to be written is known, otherwise -1. I/O containers may use this value to determine whether the
"Content-Length"
header can be set or utilize chunked transfer encoding.- Specified by:
writeResponseStatusAndHeaders
in interfaceContainerResponseWriter
- Parameters:
contentLength
- greater or equal to 0 if the content length in bytes of the entity to be written is known, otherwise -1. Containers may use this value to determine whether the"Content-Length"
header can be set or utilize chunked transfer encoding.response
- the JAX-RS response to be written. The status and headers are obtained from the response.- Returns:
- the output stream to write the entity (if any).
-
suspend
Description copied from interface:ContainerResponseWriter
Suspend the request/response processing. The method returnstrue
to indicate the response writer was suspended successfully. In case the provider has already been suspended earlier, the method returnsfalse
.I/O container must not automatically
commit
the response writer when the processing on the I/O container thread is finished and the thread is released. Instead, the Jersey runtime will make sure to manually close the container response writer instance by explicitly calling theContainerResponseWriter.commit()
orContainerResponseWriter.failure(Throwable)
method at some later point in time.Once suspended, the specified suspend timeout can be further updated using
ContainerResponseWriter.setSuspendTimeout(long, java.util.concurrent.TimeUnit)
method.- Specified by:
suspend
in interfaceContainerResponseWriter
- Parameters:
time
- time-out value. Value less or equal to 0, indicates that the processing is suspended indefinitely.unit
- time-out time unit.handler
- time-out handler to process a time-out event if it occurs.- Returns:
true
if the suspend operation completed successfully,false
otherwise.- See Also:
-
setSuspendTimeout
Description copied from interface:ContainerResponseWriter
Set the suspend timeout. Once the container response writer is suspended, the suspend timeout value can be further updated by the method.- Specified by:
setSuspendTimeout
in interfaceContainerResponseWriter
- Parameters:
time
- time-out value. Value less or equal to 0, indicates that the processing is suspended indefinitely.unit
- time-out time unit.
-
commit
public void commit()Description copied from interface:ContainerResponseWriter
Commit the response invalid input: '&' close the container response writer. Indicates to the I/O container that request has been fully processed and response has been fully written. This signals the I/O container to finish the request/response processing, clean up any state, flush any streams, release resources etc.- Specified by:
commit
in interfaceContainerResponseWriter
- See Also:
-
failure
Description copied from interface:ContainerResponseWriter
Propagate an unhandled error to the I/O container. Indicates to the I/O container that the request processing has finished with an error that could not be processed by the Jersey runtime. The I/O container is expected to process the exception in a container-specific way. This method also signals the I/O container to finish the request/response processing, clean up any state, flush any streams, release resources etc.- Specified by:
failure
in interfaceContainerResponseWriter
- Parameters:
error
- unhandled request processing error.- See Also:
-
enableResponseBuffering
public boolean enableResponseBuffering()Description copied from interface:ContainerResponseWriter
Returntrue
if the entity buffering should be enabled in Jersey. If enabled, the outbound entity is buffered by Jersey runtime up to a configured amount of bytes prior to being written to the output stream to determine its size that may be used to set the value of HTTP "Content-Length" header.Containers that provide it's own solution for determining the message payload size may decide to return
false
to prevent Jersey from buffering message entities unnecessarily.- Specified by:
enableResponseBuffering
in interfaceContainerResponseWriter
- Returns:
true
to enable entity buffering to be done by Jersey runtime,false
otherwise.
