SpdyContext (Apache Tomcat 8.0.15 API Documentation)

java.lang.Object
- org.apache.tomcat.spdy.SpdyContext

```
public final class SpdyContext
extends Object
```
Will implement polling/reuse of heavy objects, allow additional configuration. The abstract methods allow integration with different libraries ( compression, request handling ) In 'external' mode it must be used with APR library and compression. In 'intranet' mode - it is supposed to be used behind a load balancer that handles SSL and compression. Test with: --user-data-dir=/tmp/test --use-spdy=no-compress,no-ssl

Nested Class Summary

Nested Classes
Modifier and Type	Class and Description
`static class`	`SpdyContext.NetSupport`
`static interface`	`SpdyContext.NonBlockingSpdyHandler` A handler implementing this interface will be called in the 'io' thread - the thread reading the multiplexed stream, and in the case of non-blocking transports also handling polling the socket.
`static interface`	`SpdyContext.SpdyHandler`

Method Detail

setTlsCompression

public void setTlsCompression(boolean tls,
                     boolean compress)

getFrame
```
public SpdyFrame getFrame()
```
Get a frame - frames are heavy buffers, may be reused.

setFrameSize
```
public void setFrameSize(int frameSize)
```
Set the max frame size. Larger data packets will be split in multiple frames. ( the code is currently accepting larger control frames - it's not clear if we should just reject them, many servers limit header size - the http connector also has a 8k limit - getMaxHttpHeaderSize )

getStream
```
public SpdyStream getStream(SpdyConnection framer)
```
Override for server side to return a custom stream.

setExecutor

public void setExecutor(Executor executor)

setNetSupport

public void setNetSupport(SpdyContext.NetSupport netSupport)

getNetSupport

public SpdyContext.NetSupport getNetSupport()

getExecutor
```
public Executor getExecutor()
```
SPDY is a multiplexed protocol - the SpdyProcessors will be executed on this executor. If the context returns null - we'll assume the SpdyProcessors are fully non blocking, and will execute them in the spdy thread.

getHandler

public SpdyContext.SpdyHandler getHandler()

setHandler

public void setHandler(SpdyContext.SpdyHandler handler)

getConnection

public SpdyConnection getConnection(String host,
                           int port)
                             throws IOException

Client mode: return a connection for host/port.

Throws:: IOException

listen

public final void listen(int port,
          String cert,
          String key)
                  throws IOException

Throws:: IOException

stop
```
public final void stop()
                throws IOException
```
Close all pending connections and free resources.

Throws:

IOException

onStream

public void onStream(SpdyConnection spdyConnection,
            SpdyStream ch)
              throws IOException

Throws:: IOException
