Constructor Summary

JettyContinuationContainerAbstraction()

Method Summary

Sleeper	createSleeper(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response, RealScriptSession scriptSession, ScriptConduit conduit) Create a sleeper that is appropriate for the given servlet container
java.lang.Class<? extends ServerLoadMonitor>	getServerLoadMonitorImplementation() The setup process allows the ContainerAbstraction to select a special ServerLoadMonitor implementation
boolean	handleResumedRequest(javax.servlet.http.HttpServletRequest request) Some async-servlet implementations (Jetty) restart requests, when we might have already completed dealing with them.
boolean	isNativeEnvironment(javax.servlet.ServletConfig servletConfig) We ask ContainerAbstractions to identify if the environment given is 'theirs'.

Method Detail

isNativeEnvironment

public boolean isNativeEnvironment(javax.servlet.ServletConfig servletConfig)

Description copied from interface: ContainerAbstraction

We ask ContainerAbstractions to identify if the environment given is 'theirs'. Are they fit for this environment?

Specified by:

isNativeEnvironment in interface ContainerAbstraction

Parameters:

servletConfig - Access to ServletContext etc.

Returns:

true if this implementation should be used

getServerLoadMonitorImplementation

public java.lang.Class<? extends ServerLoadMonitor> getServerLoadMonitorImplementation()

Description copied from interface: ContainerAbstraction

The setup process allows the ContainerAbstraction to select a special ServerLoadMonitor implementation

Specified by:

getServerLoadMonitorImplementation in interface ContainerAbstraction

Returns:

The ServerLoadMonitor implementation to go with this container

handleResumedRequest

public boolean handleResumedRequest(javax.servlet.http.HttpServletRequest request)

Description copied from interface: ContainerAbstraction

Some async-servlet implementations (Jetty) restart requests, when we might have already completed dealing with them. If this method returns true then PollHandler will assume that we're done and will bail out before we even get started.

Specified by:

handleResumedRequest in interface ContainerAbstraction

Parameters:

request - The request that we might be finished with

Returns:

true if the request is completed

createSleeper

public Sleeper createSleeper(javax.servlet.http.HttpServletRequest request,
                             javax.servlet.http.HttpServletResponse response,
                             RealScriptSession scriptSession,
                             ScriptConduit conduit)
                      throws java.io.IOException

Description copied from interface: ContainerAbstraction

Create a sleeper that is appropriate for the given servlet container

Specified by:

response - The Sleeper will probably need to know about the response

conduit - The Sleeper will probably need to know about the conduit

Returns:

A method of sending threads to sleep.
