public ProcessAwareHttpResponse(ProcessAwareServerHttpConnectionManagedObject<B> serverHttpConnection,
                                HttpVersion version,
                                ManagedObjectContext managedObjectContext)

Instantiate.

Parameters:

serverHttpConnection - ServerHttpConnection.

version - HttpVersion.

managedObjectContext - ManagedObjectContext.

Method Detail

flushResponseToHttpResponseWriter

public void flushResponseToHttpResponseWriter(java.lang.Throwable escalation)
                                       throws java.io.IOException

Flushes the HttpResponse to the HttpResponseWriter.

Parameters:

Throws:

java.io.IOException - If fails to flush HttpResponse to the HttpResponseWriter.

getVersion

public HttpVersion getVersion()

Description copied from interface: HttpResponse

Obtains the HttpVersion.

Specified by:

getVersion in interface HttpResponse

Returns:

HttpVersion.

setVersion

public void setVersion(HttpVersion version)

Description copied from interface: HttpResponse

Override the HttpVersion.

This defaults to value on HttpRequest.

Specified by:

setVersion in interface HttpResponse

Parameters:

version - HttpVersion.

getStatus

public HttpStatus getStatus()

Description copied from interface: HttpResponse

Obtains the HttpStatus.

This is the current status. The status may changed based on particular HTTP rules (e.g. 200 becoming 204 due to no entity) or there being a failure in processing the message.

Specified by:

getStatus in interface HttpResponse

Returns:

Current HttpStatus.

setStatus

public void setStatus(HttpStatus status)

Description copied from interface: HttpResponse

Specifies the HttpStatus.

This defaults to HttpStatus.OK assuming the request was processed successfully.

Specified by:

setStatus in interface HttpResponse

Parameters:

status - HttpStatus.

getHeaders

public HttpResponseHeaders getHeaders()

Description copied from interface: HttpResponse

Obtains the HttpResponseHeaders.

Specified by:

getHeaders in interface HttpResponse

Returns:

HttpResponseHeaders.

getCookies

public HttpResponseCookies getCookies()

Description copied from interface: HttpResponse

Obtains the HttpResponseCookies.

Specified by:

getCookies in interface HttpResponse

Returns:

HttpResponseCookies.

setContentType

public void setContentType(java.lang.String contentType,
                           java.nio.charset.Charset charset)
                    throws java.io.IOException

Description copied from interface: HttpResponse

Specifies the Content-Type and optionally the Charset. The charset parameter will automatically be added to the Content-Type on using the HttpResponse.getEntityWriter().

This must be specified before calling HttpResponse.getEntityWriter().

Specified by:

setContentType in interface HttpResponse

Parameters:

contentType - Content-Type. May be null to unset the Content-Type.

charset - Charset for the Content-Type. This may be null to use the default Charset. Also use null for Content-Types that do not require character encoding (including the default HTTP content encoding).

Throws:

java.io.IOException - If attempting to specify after calling HttpResponse.getEntityWriter().

setContentType

public void setContentType(HttpHeaderValue contentTypeAndCharsetValue,
                           java.nio.charset.Charset charset)
                    throws java.io.IOException

Description copied from interface: HttpResponse

Provides means to use HttpHeaderValue to specify both the Content-Type and charset for more efficiency.

Note that HttpHeaderValue will require the inclusion of the charset, as the charset will not be appended.

Specified by:

setContentType in interface HttpResponse

Parameters:

contentTypeAndCharsetValue - HttpHeaderValue for the Content-Type and charset.

charset - Charset to configure the ServerWriter.

Throws:

java.io.IOException - If attempting to specify after calling HttpResponse.getEntityWriter().

getContentType

public java.lang.String getContentType()

Description copied from interface: HttpResponse

Obtains the Content-Type.

Specified by:

getContentType in interface HttpResponse

Returns:

Content-Type. May be null if no Content-Type has been specified.

getContentCharset

public java.nio.charset.Charset getContentCharset()

Description copied from interface: HttpResponse

Obtains the Charset for the content.

If no Charset has been specified, the default Charset will be returned.

Specified by:

getContentCharset in interface HttpResponse

Returns:

Charset.

                             throws java.io.IOException

Description copied from interface: HttpResponse

Obtains the ServerOutputStream to write the entity of the response.

Only one of HttpResponse.getEntity() or HttpResponse.getEntityWriter() may be called.

Closing the returned ServerOutputStream is similar to calling HttpResponse.send().

Specified by:

getEntity in interface HttpResponse

Returns:

ServerOutputStream to write the entity of the response.

Throws:

java.io.IOException - Should HttpResponse.getEntityWriter() already be provided.

See Also:

HttpResponse.getEntityWriter(), HttpResponse.send()

Only one of HttpResponse.getEntity() or HttpResponse.getEntityWriter() may be called.

Closing the returned ServerOutputStream is similar to calling HttpResponse.send().

Specified by:

getEntityWriter in interface HttpResponse

Returns:

ServerWriter to write the entity of the response.

Throws:

java.io.IOException - Should HttpResponse.getEntity() already be provided.

See Also:

HttpResponse.getEntity(), HttpResponse.send()

getEscalationHandler

public HttpEscalationHandler getEscalationHandler()

Description copied from interface: HttpResponse

Obtains the HttpEscalationHandler.

Specified by:

getEscalationHandler in interface HttpResponse
