Examples of com.netflix.discovery.shared.Applications

com.netflix.discovery.shared.Applications
The class that wraps all the registry information returned by eureka server.
Note that the registry information is fetched from eureka server as specified in {@link EurekaClientConfig#getRegistryFetchIntervalSeconds()}. Once the information is fetched it is shuffled and also filtered for instances with {@link InstanceStatus#UP} status as specified by the configuration{@link EurekaClientConfig#shouldFilterOnlyUpInstances()}.
