Interface ContainerAbstraction

All Known Implementing Classes:

GrizzlyContainerAbstraction, JettyContainerAbstraction, ServletSpecContainerAbstraction

public interface ContainerAbstraction

We need to keep container specific logic out of PollHandler, and other parts of DWR. Each container will need an implementation of this interface, which will generally just return configurations of generic classes.

Method Summary

Sleeper	createSleeper(javax.servlet.http.HttpServletRequest request) 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	isNativeEnvironment(javax.servlet.ServletConfig servletConfig) We ask ContainerAbstractions to identify if the environment given is 'theirs'.

Method Detail

isNativeEnvironment

boolean isNativeEnvironment(javax.servlet.ServletConfig servletConfig)

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

Parameters:

servletConfig - Access to ServletContext etc.

Returns:

true if this implementation should be used

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

Returns:

A method of sending threads to sleep.

getServerLoadMonitorImplementation

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

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

Returns:

The ServerLoadMonitor implementation to go with this container
