Class ManagedObjectPath<C extends ConfigurationClient,S extends Configuration>

java.lang.Object

org.forgerock.opendj.config.ManagedObjectPath<C,S>

Type Parameters:

C - The type of client managed object configuration that this path references.

S - The type of server managed object configuration that this path references.

public final class ManagedObjectPath<C extends ConfigurationClient,S extends Configuration>
extends Object

A path which can be used to determine the location of a managed object instance.

A path is made up of zero or more elements each of which represents a managed object. Managed objects are arranged hierarchically with the root configuration being the top-most managed object. Elements are ordered such that the root configuration managed object is the first element and subsequent elements representing managed objects further down the hierarchy.

A path can be encoded into a string representation using the toString() and toString(StringBuilder) methods. Conversely, this string representation can be parsed using the valueOf(String) method.

The string representation of a managed object path is similar in principle to a UNIX file-system path and is defined as follows:

• the root element is represented by the string /
• subordinate elements are arranged in big-endian order separated by a forward slash / character
• an element representing a managed object associated with a one-to-one (singleton) or one-to-zero-or-one (optional) relation has the form relation=relation [+type=definition ], where relation is the name of the relation and definition is the name of the referenced managed object's definition if required (usually this is implied by the relation itself)
• an element representing a managed object associated with a one-to-many (instantiable) relation has the form relation=relation [+type= definition]+name= name, where relation is the name of the relation and definition is the name of the referenced managed object's definition if required (usually this is implied by the relation itself), and name is the name of the managed object instance
• an element representing a managed object associated with a one-to-many (set) relation has the form relation=relation [+type= definition], where relation is the name of the relation and definition is the name of the referenced managed object's definition.

The following path string representation identifies a connection handler instance (note that the type is not specified indicating that the path identifies a connection handler called my handler which can be any type of connection handler):

  /relation=connection-handler+name=my handler
 

If the identified connection handler must be an LDAP connection handler then the above path should include the type:

  /relation=connection-handler+type=ldap-connection-handler+name=my handler
 

The final example identifies the global configuration:

  /relation=global-configuration
