## com.bea.p13n.property
Class AbstractConfigurableEntity

    java.lang.Object
      com.bea.p13n.property.AbstractConfigurableEntity

All Implemented Interfaces
  ConfigurableEntity, Serializable

Direct Known Subclasses:
  AbstractHierarchicalEntity, ConfigurableEntityImpl, Event

    public abstract class AbstractConfigurableEntity

extends Object
implements ConfigurableEntity, Serializable

Abstract base class for ConfigurableEntity implementations. This class provides the basic CE functionality, including explicit properties, but does not persist properties in any way. It also does not use Property Sets for property validation or default value retrieval. Any classes that wish to use the ConfigurableEntity functionality in a lightweight object should extend this.

                       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.

  Specified by:
    `getProperty` in interface `ConfigurableEntity`
  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

    public String getPropertyAsString(String propertySet,
                                      String propertyName)
                               throws RemoteException

  Convenience method to return a property as a String.

  Specified by:
    `getPropertyAsString` in interface `ConfigurableEntity`
  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

    public 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.

  Specified by:
    `getPropertyNoDefault` in interface `ConfigurableEntity`
  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

    public void setProperty(String propertySet,
                            String propertyName,
                            Object value)
                     throws PropertyValidationException,
                            RemoteException

  Associate the specified value with the named key in the specified property set.

  Specified by:
    `setProperty` in interface `ConfigurableEntity`
  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

    public 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.

  Specified by:
    `removeProperty` in interface `ConfigurableEntity`
  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.

### getUniqueId

    public long getUniqueId()
                     throws RemoteException

    `RemoteException`

### getJndiName
