Interface TenantControlFactory

  • @Beta
    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
    • Method Detail

      • saveCurrentTenant

        TenantControl saveCurrentTenant()
        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
        new TenantControl instance with the saved state of the current tenant
      • isClassesAlwaysAvailable

        boolean isClassesAlwaysAvailable()
        If the method returns false (classes are not always available), all objects, e.g. CacheConfigs are always sent over the wire in a form that does not require classes to be loaded / available. Objects will be sent using class names instead of class types, and sending byte arrays instead of serialized objects. This is so de-serialization does not fail with ClassNotFoundException
        true is the associated applications are always loaded and running
