Method Summary

Modifier and Type	Method and Description
void	abort(java.lang.Throwable failure) If a write or similar operation to this channel fails, then this method should be called.
void	badMessage(BadMessageException failure) Called to signal that a bad HTTP message has been received.
boolean	content(java.nio.ByteBuffer content)
boolean	contentComplete()
void	continue100(int available) If the associated response has the Expect header set to 100 Continue, then accessing the input stream indicates that the handler/servlet is ready for the request body and thus a 100 Continue response is sent.
void	earlyEOF() Called to signal that an EOF was received unexpectedly during the parsing of a HTTP message
int	getHeaderCacheSize()
protected void	handleException(java.lang.Throwable x) Sends an error 500, performing a special logic to detect whether the request is suspended, to avoid concurrent writes from the application.
boolean	headerComplete()
boolean	isExpecting100Continue()
boolean	isExpecting102Processing()
boolean	messageComplete()
protected HttpInput	newHttpInput(HttpChannelState state)

Constructor Detail

HttpChannelOverHttp

public HttpChannelOverHttp(HttpConnection httpConnection,
                           Connector connector,
                           HttpConfiguration config,
                           EndPoint endPoint,
                           HttpTransport transport)

Method Detail

newHttpInput

protected HttpInput newHttpInput(HttpChannelState state)

Overrides:

newHttpInput in class HttpChannel

recycle

public void recycle()

Overrides:

recycle in class HttpChannel

isExpecting100Continue

public boolean isExpecting100Continue()

Overrides:

isExpecting100Continue in class HttpChannel

isExpecting102Processing

public boolean isExpecting102Processing()

Overrides:

isExpecting102Processing in class HttpChannel

startRequest

public boolean startRequest(java.lang.String method,
                            java.lang.String uri,
                            HttpVersion version)

Description copied from interface: HttpParser.RequestHandler

This is the method called by parser when the HTTP request line is parsed

Specified by:

startRequest in interface HttpParser.RequestHandler

Parameters:

method - The method

uri - The raw bytes of the URI. These are copied into a ByteBuffer that will not be changed until this parser is reset and reused.

version - the http version in use

Returns:

true if handling parsing should return.

parsedHeader

public void parsedHeader(HttpField field)

Description copied from interface: HttpParser.HttpHandler

This is the method called by parser when a HTTP Header name and value is found

Specified by:

parsedHeader in interface HttpParser.HttpHandler

Parameters:

field - The field parsed

parsedTrailer

public void parsedTrailer(HttpField field)

Description copied from interface: HttpParser.HttpHandler

This is the method called by parser when a HTTP Trailer name and value is found

Specified by:

parsedTrailer in interface HttpParser.HttpHandler

Parameters:

field - The field parsed

continue100

public void continue100(int available)
                 throws java.io.IOException

If the associated response has the Expect header set to 100 Continue, then accessing the input stream indicates that the handler/servlet is ready for the request body and thus a 100 Continue response is sent.

Overrides:

continue100 in class HttpChannel

Parameters:

available - estimate of the number of bytes that are available

Throws:

java.io.IOException - if the InputStream cannot be created

earlyEOF

public void earlyEOF()

Description copied from interface: HttpParser.HttpHandler

Called to signal that an EOF was received unexpectedly during the parsing of a HTTP message

Specified by:

earlyEOF in interface HttpParser.HttpHandler

content

public boolean content(java.nio.ByteBuffer content)

Specified by:

content in interface HttpParser.HttpHandler

onAsyncWaitForContent

public void onAsyncWaitForContent()

Overrides:

onAsyncWaitForContent in class HttpChannel

onBlockWaitForContent

public void onBlockWaitForContent()

Overrides:

onBlockWaitForContent in class HttpChannel

onBlockWaitForContentFailure

public void onBlockWaitForContentFailure(java.lang.Throwable failure)

Overrides:

onBlockWaitForContentFailure in class HttpChannel

badMessage

public void badMessage(BadMessageException failure)

Description copied from interface: HttpParser.HttpHandler

Called to signal that a bad HTTP message has been received.

Specified by:

badMessage in interface HttpParser.HttpHandler

Parameters:

failure - the failure with the bad message information

headerComplete

public boolean headerComplete()

Specified by:

headerComplete in interface HttpParser.HttpHandler

handleException

protected void handleException(java.lang.Throwable x)

Description copied from class: HttpChannel

Sends an error 500, performing a special logic to detect whether the request is suspended, to avoid concurrent writes from the application.

It may happen that the application suspends, and then throws an exception, while an application spawned thread writes the response content; in such case, we attempt to commit the error directly bypassing the ErrorHandler mechanisms and the response OutputStream.

Overrides:

handleException in class HttpChannel

Parameters:

x - the Throwable that caused the problem

abort

public void abort(java.lang.Throwable failure)

Description copied from class: HttpChannel

If a write or similar operation to this channel fails, then this method should be called.

The standard implementation calls HttpTransport.abort(Throwable).

Overrides:

abort in class HttpChannel

Parameters:

failure - the failure that caused the abort.

contentComplete

public boolean contentComplete()

Specified by:

contentComplete in interface HttpParser.HttpHandler

messageComplete

public boolean messageComplete()

Specified by:

messageComplete in interface HttpParser.HttpHandler

getHeaderCacheSize

public int getHeaderCacheSize()

Specified by:

getHeaderCacheSize in interface HttpParser.HttpHandler

Returns:

the size in bytes of the per parser header cache

onComplianceViolation

public void onComplianceViolation(HttpCompliance compliance,
                                  HttpComplianceSection violation,
                                  java.lang.String reason)

Specified by:

onComplianceViolation in interface HttpParser.ComplianceHandler
