- public class ReloadInterceptor
- extends BaseInterceptor
This interceptor deals with context reloading.
This should be "AT_END" - just after the context is mapped, it
will determine if the context needs reload.
This interceptor supports multiple forms of reloading.
Configuration. Must be set after LoaderInterceptor

ReloadInterceptor
public ReloadInterceptor()
engineInit
public void engineInit(ContextManager cm)
throws TomcatException
- Description copied from class:
BaseInterceptor
- Initialize the module.
- Overrides:
engineInit
in class BaseInterceptor
- Following copied from class:
org.apache.tomcat.core.BaseInterceptor
- Throws:
TomcatException
- The module will not be added if any
exception is thrown by engineInit.
setFullReload
public void setFullReload(boolean full)
- A full reload will stop and start the context, without
saving any state. It's the cleanest form of reload, equivalent
with (partial) server restart.
addContext
public void addContext(ContextManager cm,
Context context)
throws TomcatException
- Description copied from class:
BaseInterceptor
- Called when a context is added to a CM. The context is probably not
initialized yet, only path, docRoot, host, and properties set before
adding the context ( in server.xml for example ) are available.
At this stage mappers can start creating structures for the
context ( the actual loading of the context may be delayed in
future versions of tomcat until the first access ).
DefaultCMSetter will also adjust the logger and paths
based on context manager properties.
Any activity that depends on web.xml must be done at
init time.
- Overrides:
addContext
in class BaseInterceptor
contextInit
public void contextInit(Context context)
throws TomcatException
- Example of adding web.xml to the dependencies.
JspInterceptor can add all taglib descriptors.
- Overrides:
contextInit
in class BaseInterceptor
- Following copied from class:
org.apache.tomcat.core.BaseInterceptor
- Throws:
If
- the interceptor throws exception the context will
not be initialized ( state==NEW or ADDED or DISABLED ).
reload
public void reload(Request req,
Context context)
throws TomcatException
- Description copied from class:
BaseInterceptor
- Reload notification - called whenever a reload is done.
This can be used to serialize sessions, log the event,
remove any resource that was class-loader dependent.
Note. The current implementation uses a note "oldLoader"
that will keep a reference to the previous class loader
during this hook. It will be set by the module that creates
the loaders, and should be destroyed when the hook is done.
This can also be implemented using a get/setOldClassLoader
in Context, but so far this is used in only 2 modules, adding
new API is not needed.
- Overrides:
reload
in class BaseInterceptor
loaderHook
protected void loaderHook(DependManager dm,
Context context)
contextMap
public int contextMap(Request request)
- Description copied from class:
BaseInterceptor
- Will detect the context path for a request.
It need to set: context, contextPath, lookupPath
A possible use for this would be a "user-home" interceptor
that will implement ~costin servlets ( add and map them at run time).
- Overrides:
contextMap
in class BaseInterceptor
