Method Detail

decorateProcessor

protected void decorateProcessor(NutsProcessor processor,
                                 javax.servlet.ServletContext ctxt)
                          throws java.lang.Exception

Description copied from class: YanLoader

Decorate a NutsProcessor object by adding or removing features.

This default implementation replaces <bean>, <ctor> and <method> tags with the ones that're aware of the ServletContext.

It does so by registering the ServletContext as a service under YanLoader.SERVLET_CONTEXT_KEY. The customized tags then look up this service and call "setServletContext()" or any other specified receiver method to set this dependency.

Based on whether YanLoader.USE_SPRING parameter is set in ServletContext, this implementation calls either YanLoader.setSpringAware(NutsProcessor, ServletContext) or YanLoader.setWebAware(NutsProcessor, ServletContext) to do the decoration.

Subclasses can override this method to provide customized decoration.

Overrides:

decorateProcessor in class YanLoader

Parameters:

processor - the NutsProcessor object to decorate.

ctxt - the ServletContext object.

Throws:

java.lang.Exception - any error.

initContainer

public Container initContainer(java.lang.ClassLoader cloader,
                               javax.servlet.ServletContext servletContext)

Description copied from class: YanLoader

Initialize this object by instantiating container and life cycle manager. Relevant servlet context parameters are read.

This implementation calls YanLoader.process(ClassLoader, ServletContext) for interpreting the configuration file and obtaining the Container instance and LifecycleManager instance.

Overrides:

initContainer in class YanLoader

Parameters:

cloader - the ClassLoader used to load component classes.

servletContext - the servlet context object.

Returns:

the Container object instantiated. null is returned if configuration file not found.
