Interface EntityPropertyManager

All Superinterfaces:
  EJBObject, Remote

All Known Subinterfaces:
  CustomerPropertyManager, LdapPropertyManager

public interface EntityPropertyManager
extends EJBObject

EntityPropertyManager is the remote interface for a session bean that manages persistence of ConfigurableEntity EJB's and their properties. The default implementation uses the WLPS database as its backing store, other implementations may use other datastores such as an LDAP server.

Each ConfigurableEntity must have an ejb-ref in its deployment descriptor that can be used to identify the correct EntityPropertyManager to use.

Method Detail

### createUniqueId

    public long createUniqueId(String jndiHomeName,
                               String pkString)
                        throws RemoteException,
                               ConfigurableEntityCreateException

  Create a record for a new ConfigurableEntity, as identified by the given jndiHomeName and pkString.

  Parameters:
    `jndiHomeName` - the entity's home name
    `pkString` - the entity's identifier string
  Returns:
    the newly created entity id
  Throws:
    `ConfigurableEntityCreateException` - if there is an error
    `RemoteException`

### getDynamicProperties

    public String[] getDynamicProperties(PropertyLocator locator,
                                         String propertySet)
                                  throws RemoteException,
                                         EntityNotFoundException

  Returns a list of dynamically assigned properties for the given entity, that have been named with the given property set name. Dynamic properties are properties that have values persisted, and may even have a property set name, but are not actually defined in a property set.

  Dynamic properties could exist if the property set definition has been changed to remove a property but the given entity still has a value for this property. They could also exist if the entity has properties that were set using the property set name as the scope, but the property set definition does not contain the properties.

  If the given property set name is null then this method returns the property names that were set for this entity using null for the property set name.

  Parameters:
    `locator` - a PropertyLocator identifying the entity to look up
    `propertySet` - the propertySet to look up
  Returns:
    a String array of property names
  Throws:
    `RemoteException`
    `EntityNotFoundException`

### getEntityNames

  Return a list of Entity names that have this jndi name.

  Parameters:
    `jndiName` - the jndiName to query
  Returns:
    a list of entity names, or null if none were found
  Throws:
    `RemoteException`

### getHomeName

    public String getHomeName(long anEntityId)
                       throws RemoteException,

  Get the JNDI home name for the entity identified by the given entity id

  Parameters:
    `anEntityId` - the unique id for the entity to look up

    `RemoteException`
    `EntityNotFoundException`

### getProperties

    public EntityPropertyCache getProperties(PropertyLocator locator)
                                      throws RemoteException,
