OsgiServletContext (OPS4J Pax Web - Service SPI (internal) 8.0.27 API)

java.lang.Object
- org.ops4j.pax.web.service.spi.servlet.OsgiServletContext

All Implemented Interfaces:

javax.servlet.ServletContext
```
public class OsgiServletContext
extends Object
implements javax.servlet.ServletContext
```
Implementation of ServletContext for the contract described in 140.2.6 "Behavior of the Servlet Context" from OSGi CMPN R7 Whiteboard Service specification. That's the 1:1 mapping with single ServletContextHelper (or HttpContext).

When handling single servlet (or generally filters+servlet chain), we have to provide special facade for ServletContext from Servlet API in the form of OsgiServletContext. And during actual request processing, we need yet another facade to provide required ServletContext.getClassLoader() behavior.

public OsgiServletContext(javax.servlet.ServletContext containerServletContext,
                          OsgiContextModel osgiContextModel,
                          ServletContextModel servletContextModel,
                          javax.servlet.SessionCookieConfig defaultSessionCookieConfig,
                          ClassLoader loader)
```
    Constructor called when OsgiContextModel is passed to given ServerController. We still can't grab an instance of WebContainerContext in the constructor, because it has to be resolved in the context of particular web request invocation - target Servlet determines the OsgiContextModel used and the Bundle associated with the target Servlet is used to resolve actual WebContainerContext.
    
    Parameters:
    
    containerServletContext -
    
    osgiContextModel -
    
    servletContextModel -
    
    loader -
- Method Detail
  - getResolvedWebContainerContext
```
public org.ops4j.pax.web.service.WebContainerContext getResolvedWebContainerContext()
```
  - register
```
public void register()
```
    A server wrapper that finds this OsgiServletContext to be highest ranked for given physical ServletContext should register it as OSGi service for given context path.
    
    This behavior is defined in "128.3.4 Publishing the Servlet Context" and concerns only WAB contexts, but I see no problems registering the current OsgiServletContext for given context path for all cases (including HttpService and Whiteboard).
  - unregister
```
public void unregister()
```
    A server wrapper that finds this OsgiServletContext to no longer be highest ranked for given physical ServletContext should unregister it from OSGi service registry.
  - releaseWebContainerContext
```
public void releaseWebContainerContext()
```
    Everywhere the OsgiServletContext is created, we have to call BundleContext.ungetService(ServiceReference) on the WebContainerContext reference when needed.
  - getAttributesToClearBeforeRestart
```
public Set<String> getAttributesToClearBeforeRestart()
```
  - clearAttributesFromPreviousCycle
```
public void clearAttributesFromPreviousCycle()
```
    This method removes the attributes set by SCIs in previous restart of the context.
  - getOsgiContextModel
```
public OsgiContextModel getOsgiContextModel()
```
  - getServletContextModel
```
public ServletContextModel getServletContextModel()
```
  - setContainerServletContext
```
public void setContainerServletContext(javax.servlet.ServletContext containerServletContext)
```
    We have to be able to replace server-specific ServletContext, because we can't freely replace web elements in Undertow. In Undertow we have to recreate entire context, thus getting new ServletContext. Also Tomcat replaces a context (facade) inside StandardContext
    
    Parameters:
    
    containerServletContext -
  - getContainerServletContext
```
public javax.servlet.ServletContext getContainerServletContext()
```
  - getWelcomeFiles
```
public String[] getWelcomeFiles()
```
  - setWelcomeFiles
```
public void setWelcomeFiles(String[] welcomeFiles)
```
  - isWelcomeFilesRedirect
```
public boolean isWelcomeFilesRedirect()
```
  - setWelcomeFilesRedirect
```
public void setWelcomeFilesRedirect(boolean redirect)
```
  - noMoreServletContextListeners
```
public void noMoreServletContextListeners()
```
    This will mark the OsgiServletContext as a context that still alows for dynamic registration, but not if the listener implements ServletContextListener
  - acceptsServletContextListeners
```
public boolean acceptsServletContextListeners()
```
    Can ServletContextListener be registered?
    
    Returns:
  - allowServletContextListeners
```
public void allowServletContextListeners()
```
    This method should be called with the associated context starts, so SCIs can register ServletContextListener listeners
