Constructor Detail

SimpleDirectory

public SimpleDirectory()

Creates a new empty SimpleDirectory which does not provide access to any objects.

SimpleDirectory

public SimpleDirectory(Map<String,ObjectType> objects)

Creates a new SimpleDirectory which provides access to the objects contained within the given Map.

Parameters:

objects - The Map of objects to provide access to.

Method Detail

setObjects

protected void setObjects(Map<String,ObjectType> objects)

Sets the Map which backs this SimpleDirectory. Future function calls which retrieve objects from this SimpleDirectory will use the provided Map.

Parameters:

objects - The Map of objects to provide access to.

getObjects

protected Map<String,ObjectType> getObjects()

Returns the Map which currently backs this SimpleDirectory. Changes to this Map will affect future function calls that retrieve objects from this SimpleDirectory.

Returns:

The Map of objects which currently backs this SimpleDirectory.

get

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

Description copied from interface: Directory

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.

Specified by:

get in interface Directory<ObjectType extends Identifiable>

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

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

Description copied from interface: Directory

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.

Specified by:

getAll in interface Directory<ObjectType extends Identifiable>

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

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

Description copied from interface: Directory

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

Specified by:

getIdentifiers in interface Directory<ObjectType extends Identifiable>

Returns:

A Set of all identifiers.

Throws:

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

add

public void add(ObjectType connection)
         throws org.apache.guacamole.GuacamoleException

Description copied from interface: Directory

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().

Specified by:

add in interface Directory<ObjectType extends Identifiable>

Parameters:

connection - 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

public void update(ObjectType connection)
            throws org.apache.guacamole.GuacamoleException

Description copied from interface: Directory

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

Specified by:

update in interface Directory<ObjectType extends Identifiable>

Parameters:

connection - 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

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

Description copied from interface: Directory

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

Specified by:

remove in interface Directory<ObjectType extends Identifiable>

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.
