Class HttpTransport

java.lang.Object

com.predic8.membrane.core.transport.Transport

com.predic8.membrane.core.transport.http.HttpTransport

public class HttpTransport
extends Transport

Description

The transport receives messages from clients and invokes interceptors in the request and response flow. The interceptors that are engaged with the transport are global and are invoked for each message flowing through the router.

Method Detail

init

public void init(Router router)
          throws Exception

Overrides:

init in class Transport

Throws:

Exception

isAnyThreadListeningAt

public boolean isAnyThreadListeningAt(String ip,
                                      int port)

getAllPorts

public Enumeration<IpPort> getAllPorts()

closePort

public void closePort(String ip,
                      int port)
               throws IOException

Closes the corresponding server port. Note that connections might still be open and exchanges still running after this method completes.

Throws:

IOException

closeAll

public void closeAll(boolean waitForCompletion)
              throws IOException

Overrides:

closeAll in class Transport

Throws:

IOException

openPort

public void openPort(String ip,
                     int port,
                     SSLProvider sslProvider)
              throws IOException

Overrides:

openPort in class Transport

Parameters:

port -

Throws:

IOException

getOpenBackendConnections

public String getOpenBackendConnections(int port)

Overrides:

getOpenBackendConnections in class Transport

getCoreThreadPoolSize

public int getCoreThreadPoolSize()

setCoreThreadPoolSize

public void setCoreThreadPoolSize(int corePoolSize)

Default

20

Description

Membrane uses a thread pool to allocate threads to incomming clients connections. The core thread pool size is the minimum number of threads that are created in advance to serve client requests.

Example

5

getMaxThreadPoolSize

public int getMaxThreadPoolSize()

setMaxThreadPoolSize

public void setMaxThreadPoolSize(int value)

Default

no limit

Description

Maximum number of threads to handle incoming connections. (Membrane uses 1 thread per incoming connection.)

Example

300

getExecutorService

public ExecutorService getExecutorService()

getSocketTimeout

public int getSocketTimeout()

setSocketTimeout

public void setSocketTimeout(int timeout)

Default

30000

Description

Socket timout in ms.

isTcpNoDelay

public boolean isTcpNoDelay()

setTcpNoDelay

public void setTcpNoDelay(boolean tcpNoDelay)

Default

true

Description

Whether to use the "TCP no delay" option. (=A TCP/IP packet should be constructed as soon as any data has been written to the network buffer. With "TCP no delay" set to false, the network hardware waits a short period of time wether the software will write more data. When the packet constructed from the data in the buffer would exceed the MTU in size, the packet is always constructed and sent immediately.)

isOpeningPorts

public boolean isOpeningPorts()

Specified by:

isOpeningPorts in class Transport

getForceSocketCloseOnHotDeployAfter

public int getForceSocketCloseOnHotDeployAfter()

setForceSocketCloseOnHotDeployAfter

public void setForceSocketCloseOnHotDeployAfter(int forceSocketCloseOnHotDeployAfter)

Default

30000

Description

When proxies.xml is changed and <router hotDeploy="true">, the Spring Context is automatically refreshed, which restarts the Router object (=Membrane Service Proxy). Before the context refresh, all open socket connections have to be closed. Exchange objects which are still running might delay this process. Setting forceSocketCloseOnHotDeployAfter to a non-zero number of milliseconds forces connections to be closed after this time.
