Direct Known Subclasses:

AwsFilterChainManager

public abstract class FilterChainManager<ServletContextType extends jakarta.servlet.ServletContext>
extends Object

This object is in charge of matching a servlet request to a set of filters, creating the filter chain for a request, and cache filter chains that were already loaded for re-use. This object should be used by the framework-specific implementations that use the HttpServletRequest and HttpServletResponse objects. For example, the Spring implementation creates the ServletContext when the application is initialized the first time and creates a FilterChainManager to execute its filters for each request.
