public interface ConfigurableEntity

The ConfigurableEntity provides the interface to an Entity that can be configured at runtime by associating properties via name-value pairs. The values are permanently associated with the entity by use of the EntityPropertyManager.

The name to associate the value with is made of an optional property set name and a key. Property sets define namespaces for keys. Duplicate keys are allowed in different property sets, and not specifying a property set means the "default" property set.

Entities that derive from ConfigurableEntity will require that the EntityPropertyManager and PropertySetType environment variables be set in their EJB deployment descriptors.

The EntityPropertyManager is a stateless session bean that is used to persist the runtime properties. That bean in turn can be configured to persist its properties in a separate set of tables.

Method Detail

getProperty

Object getProperty(String propertySet,
                   String propertyName)
                   throws RemoteException
Retrieve the value that was persisted for this entity for the given property, within the given property set. If the entity does not have a value persisted for this property, the default value from the property set will be returned.

Parameters
propertySet - The name of the property set to look in
propertyName - The name of the property to retrieve.
Returns
the value for this property, or null if all searches failed
Throws
RemoteException

getPropertyAsString

String getPropertyAsString(String propertySet,
                           String propertyName)
                           throws RemoteException
Convenience method to return a property as a String.

Parameters
propertySet - The name of the property set to look in
propertyName - The name of the property to retrieve.
Returns
the value for this property as a String, or null if all searches failed
Throws
RemoteException

getPropertyNoDefault

Object getPropertyNoDefault(String propertySet,
                            String propertyName)
                            throws RemoteException
Retrieve the value associated with the named key in the specified property set, but does not return a default value from the property's PropertyDefinition if a value was not persisted for this entity. This method is used by the implementation of the getProperty methods so that the search in the successor hierarchy does not return a default value from the Schema.

Parameters
propertySet - The name of the property set
propertyName - The name of the property to retrieve.
Returns
the value for this property, or null if all searches failed
Throws
RemoteException

setProperty

void setProperty(String propertySet,
                 String propertyName,
                 Object value)
                 throws PropertyValidationException,
                        RemoteException
Associate the specified value with the named key in the specified property set.

Parameters
propertySet - The name of the property set.
propertyName - The name of the property to assign
value - The value to associate with the property name
Throws
PropertyValidationException - If the property value does not match the PropertyDefinition for this property set
RemoteException

removeProperty

Object removeProperty(String propertySet,
                      String propertyName)
                      throws RemoteException
Remove the property associated with the named key in the specified property set.

NOTE: if an explicit setter method is found for this property, this method will set the value to null.

Parameters
propertySet - The name of the property set.
propertyName - The name of the property to remove.
Returns
the old value of the property, or null if there was none.
Throws
RemoteException

getUniqueId

long getUniqueId()
                 throws RemoteException
Retrieve the unique identifier generated for this ConfigurableEntity. The unique identifier is used by the EntityPropertyManager to optimize the foreign keys in the persistent storage. This method may not be implemented in a lightweight implementation of ConfigurableEntity.

Returns
this entity's unique id
Throws
RemoteException

getPkString

String getPkString()
                   throws RemoteException
Retrieve the pk string for an entity. A combination of pk string and jndi name is always unique between entities.

Returns
the primary key string identifier for this entity
Throws
RemoteException

getJndiName

String getJndiName()
                   throws RemoteException
Retrieve the jndi name for an entity. A combination of pk string and jndi name is always unique between entities.

Returns
the jndi name for this entity
Throws
RemoteException
