Interface ContainerFactory

All Known Implementing Classes:

DefaultContainerFactory

public interface ContainerFactory

Allows applications using Johnson to provide custom JohnsonEventContainer implementations for use as part of their configuration.

For example, multi-tenant applications need a way to group events in the container per-tenant, allowing tenants to see only those application and request events which relate to their view of the system. In such a scenario, the application may register a custom ContainerFactory which returns a tenant-aware container. This keeps any dependency on or knowledge of multi-tenancy libraries Johnson.

Method Detail

create

@Nonnull
JohnsonEventContainer create()

Creates a JohnsonEventContainer for use storing events.

This method will be called exactly once during Johnson initialisation, and the returned event container will be used to service all requests on all threads. As a result, the returned implementation is required to be thread-safe. For multi-tenant systems, handling the differentiation between events for each tenant must happen below the interface, on a single instance (at least from Johnson's perspective) of the container.

Returns:

an event container
