public interface TenantControlFactory
A TenantControlFactory supplies TenantControl objects when Hazelcast service attaches the tenant control to a distributed object. An implementation of TenantControlFactory is instantiated via ServiceLoader, so in order to be picked up:
  • Its class name must be stored in a service definition file in META-INF/services/com.hazelcast.spi.tenantcontrol.TenantControlFactory
  • It must have a public no-args constructor
  • Field Details

  • Method Details

    • saveCurrentTenant

      TenantControl saveCurrentTenant​(DestroyEventContext event)
      To be called from the application's thread to connect a Hazelcast object with a particular tenant, e.g. JCache-based cache with a particular application Implementor will save the current thread context and return it Further operations from other threads will use the returned context for this particular Hazelcast object to re-establish the invocation context
      event - hook to destroy any Hazelcast object when the tenant is destroyed, This is used, for example, to delete all associated caches from the application when it gets undeployed, so there are no ClassCastExceptions afterwards
