Field Detail

config

protected Config config

ServletConfig or FilterConfig.

decoratorMapper

protected DecoratorMapper decoratorMapper

Instance of DecoratorMapper. Because it is thread-safe, it can be shared by multiple clients. This is only the last DecoratorMapper in the chain, and all parents will be automatically delegated to it.

pageParsers

protected java.util.Map pageParsers

Map that associates content-types with PageParser instances.

excludeUrls

protected PathMapper excludeUrls

A map of paths that are excluded from decoration

Constructor Detail

BaseFactory

protected BaseFactory(Config config)

Constructor for default implementation of Factory. Should never be called by client. Singleton instance should be obtained instead.
