Examples of org.impalaframework.module.spi.Application

org.impalaframework.module.spi.Application
Holds mutable application state held by the Impala runtime. The Impala runtime can manage multiple {@link Application} instances at a time, but typically only one of these willbe active at a time. There are a number of potential use cases for the capability. One is to allow for seamless implementation of module upgrades. Intead of changing the currently {@link Application} instance, a new {@link Application}instance can be loaded and populated in the background. If and when this is loaded successfully, requests can be routed to this instance, after which the old instance can be shut down. Another use case is to allow for multiple virtual applications hosted within the same web container. @author Phil Zoio
