    public class SimpleDirectory<ObjectType extends Identifiable>
    extends Object
    implements Directory<ObjectType>
    An extremely simple read-only implementation of a Directory which provides access to a pre-defined Map of arbitrary objects. Any changes to the Map will affect the available contents of this SimpleDirectory.
    • 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. The given Map will be used to back all operations on the SimpleDirectory.
        Parameters:
        objects - The Map of objects to provide access to.
      • SimpleDirectory

        public SimpleDirectory​(ObjectType object)
        Creates a new SimpleDirectory which provides access to the given object.
        Parameters:
        object - The object to provide access to.
      • SimpleDirectory

        @SafeVarargs
        public SimpleDirectory​(ObjectType... objects)
        Creates a new SimpleDirectory which provides access to the given objects. Note that a new Map will be created to store the given objects. If the objects are already available in Map form, it is more efficient to use the SimpleDirectory(java.util.Map) constructor.
        Parameters:
        objects - The objects that should be present in this directory.
      • SimpleDirectory

        public SimpleDirectory​(Collection<ObjectType> objects)
        Creates a new SimpleDirectory which provides access to the objects contained within the Collection. Note that a new Map will be created to store the given objects. If the objects are already available in Map form, it is more efficient to use the SimpleDirectory(java.util.Map) constructor.
        Parameters:
        objects - A Collection of all objects that should be present in this directory.
    • 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

        Specified by:
        update in interface Directory<ObjectType extends Identifiable>
        Parameters:
        connection - The object which will supply the data for the update.

        Parameters:
        identifier - The identifier of the object to remove.
