Package org.apache.guacamole.net.auth

Interface Directory<ObjectType extends Identifiable>

Type Parameters:

ObjectType - The type of objects stored within this Directory.

All Known Implementing Classes:

DecoratingDirectory, DelegatingDirectory, SimpleConnectionDirectory, SimpleConnectionGroupDirectory, SimpleDirectory, SimpleUserDirectory

public interface Directory<ObjectType extends Identifiable>

Provides access to a collection of all objects with associated identifiers, and allows user manipulation and removal. Objects returned by a Directory are not necessarily backed by the stored objects, thus updating an object always requires calling the update() function.

Method Summary

Modifier and Type	Method	Description
void	add(ObjectType object)	Adds the given object to the overall set.
ObjectType	get(String identifier)	Returns the object having the given identifier.
Collection<ObjectType>	getAll(Collection<String> identifiers)	Returns the objects having the given identifiers.
Set<String>	getIdentifiers()	Returns a Set containing all identifiers for all objects within this Directory.
void	remove(String identifier)	Removes the object with the given identifier from the overall set.
void	update(ObjectType object)	Updates the stored object with the data contained in the given object.

Method Detail

get

ObjectType get(String identifier)
        throws org.apache.guacamole.GuacamoleException

Returns the object having the given identifier. Note that changes to the object returned will not necessarily affect the object stored within the Directory. To update an object stored within an Directory such that future calls to get() will return the updated object, you must call update() on the object after modification.

Parameters:

identifier - The identifier to use when locating the object to return.

Returns:

The object having the given identifier, or null if no such object exists.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while retrieving the object, or if permission for retrieving the object is denied.

getAll

Collection<ObjectType> getAll(Collection<String> identifiers)
                       throws org.apache.guacamole.GuacamoleException

Returns the objects having the given identifiers. Note that changes to any object returned will not necessarily affect the object stored within the Directory. To update an object stored within a Directory such that future calls to get() will return the updated object, you must call update() on the object after modification.

Parameters:

identifiers - The identifiers to use when locating the objects to return.

Returns:

The objects having the given identifiers. If any identifiers do not correspond to accessible objects, those identifiers will be ignored. If no objects correspond to any of the given identifiers, the returned collection will be empty.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while retrieving the objects, or if permission to retrieve the requested objects is denied.

getIdentifiers

Set<String> getIdentifiers()
                    throws org.apache.guacamole.GuacamoleException

Returns a Set containing all identifiers for all objects within this Directory.

Returns:

A Set of all identifiers.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while retrieving the identifiers.

add

void add(ObjectType object)
  throws org.apache.guacamole.GuacamoleException

Adds the given object to the overall set. If a new identifier is created for the added object, that identifier will be automatically assigned via setIdentifier().

Parameters:

object - The object to add.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while adding the object, or if adding the object is not allowed.

update

void update(ObjectType object)
     throws org.apache.guacamole.GuacamoleException

Updates the stored object with the data contained in the given object.

Parameters:

object - The object which will supply the data for the update.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while updating the object, or if updating the object is not allowed.

remove

void remove(String identifier)
     throws org.apache.guacamole.GuacamoleException

Removes the object with the given identifier from the overall set.

Parameters:

identifier - The identifier of the object to remove.

Throws:

org.apache.guacamole.GuacamoleException - If an error occurs while removing the object, or if removing object is not allowed.
