Shared Module Services

SyncServiceContainer

When Hagrid runs the sync then it creates a container named SyncServiceContainer specifically for this particular sync. Hagrid adds all services that it initialized for this sync into this container. It is very much like Spring ApplicationContext container.

However, there is one difference, Spring container is init only once per Java application, SyncServiceContainer of hagrid is different for each sync that it runs.

If you have access to SyncServiceContainer, you can access any internal service that hagrid has intialized to run this sync.

Below is the visualisation of the SyncServiceContainer

SyncServiceContainer exposes two methods via which you can fetch any service.

public <T> T getBean(String bean);
public <T> T getBean(Class<T> bean);

Suppose you want to fetch TraverseConfigService to configure dynamic rate limit then you can use SyncServiceContainer like below

TraverseConfigService traverseConfigService = syncServiceContainer.getBean(TraverseConfigService.class);
traverseConfigService.setStepRateLimit(FbUser.class, 200, 20);

If you fetch some service which is not Hagrid Managed then getBean method of the SyncServiceContainer service will automatically fetch is from Spring Application Container
