    • getId

      public Object getId(Object domainObject)
      Description copied from class: ServiceLayer
      Return the persistent id for a domain object. May return null to indicate that the domain object has not been persisted. The value returned from this method must be a simple type (e.g. Integer, String) or a domain type for which a mapping to an EntityProxy or Value proxy exists.

      The values returned from this method may be passed to ServiceLayer.loadDomainObject(Class, Object) in the future.

      Overrides:
      getId in class ServiceLayerDecorator
      Parameters:
      domainObject - a domain object
      Returns:
      the persistent id of the domain object or null if the object is not persistent

    • getIdType

      public Class<?> getIdType(Class<?> domainType)
      Description copied from class: ServiceLayer
      Returns the type of object the domain type's findFoo() or Locator.getId() expects to receive.
      Overrides:
      getIdType in class ServiceLayerDecorator
      Parameters:
      domainType - a domain entity type
      Returns:
      the type of the persistent id value used to represent the domain type

    • getProperty

      public Object getProperty(Object domainObject, String property)
      Description copied from class: ServiceLayer
      Retrieve the named property from the domain object.
      Overrides:
      getProperty in class ServiceLayerDecorator
      Parameters:
      domainObject - the domain object being examined
      property - the property name
      Returns:
      the value of the property

    • getRequestReturnType

      public Type getRequestReturnType(Method contextMethod)
      Description copied from class: ServiceLayer
      Compute the return type for a method declared in a RequestContext by analyzing the generic method declaration.
      Overrides:
      getRequestReturnType in class ServiceLayerDecorator

    • getSetter

      public Method getSetter(Class<?> domainType, String property)
      Description copied from class: ServiceLayer
      Determine the method to invoke when setting the given property.
      Overrides:
      getSetter in class ServiceLayerDecorator
      Parameters:
      domainType - a domain entity type
      property - the name of the property to be set
      Returns:
      the Method that should be invoked to set the property or null if the method could not be located

    • getVersion

      public Object getVersion(Object domainObject)
      Description copied from class: ServiceLayer
      May return null to indicate that the domain object has not been persisted. The value returned from this method must be a simple type (e.g. Integer, String) or a domain type for which a mapping to an EntityProxy or Value proxy exists.
      Overrides:
      getVersion in class ServiceLayerDecorator
      Parameters:
      domainObject - a domain object
      Returns:
      the version of the domain object or null if the object is not persistent

    • invoke

      public Object invoke(Method domainMethod, Object... args)
      Description copied from class: ServiceLayer
      Invoke a domain service method. The underlying eventually calls Method.invoke(Object, Object...).
      Overrides:
      invoke in class ServiceLayerDecorator
      Parameters:
      domainMethod - the method to invoke
      args - the arguments to pass to the method
      Returns:
      the value returned from the method invocation

    • isLive

      public boolean isLive(Object domainObject)
      This implementation attempts to re-load the object from the backing store.
      Overrides:
      isLive in class ServiceLayerDecorator
      Parameters:
      domainObject - a domain entity
      Returns:
      true if domainObject could be retrieved at a later point in time

    • loadDomainObject

      public <T> T loadDomainObject(Class<T> clazz, Object id)
      Description copied from class: ServiceLayer
      Load an object from the backing store. This method may return null to indicate that the requested object is no longer available.

      T - the type of data being validated
      Parameters:
