public interface FolderInterface
extends MetadataInterface, MutableContainerInterface

This is a generic interface for interacting with a Folder object.

Note: This interface currently has no support for ordering of items within a Folder although the contents are returned in an ordered list. It may be useful to subclass the list of items to allow sorting by name, date created, date modified, etc.

1.0

static final String FOLDER_TYPE_BIP

The type string that most BIP applications like.

• Constant Field Values

Method Details

getPath

String getPath()
        throws RemoteException

Get path of the current folder. This is the path starting with the Tree just below the Bip Service SoftwareComponent down to this folder, with forward-slash separators.

Returns:

The path string for this folder.

Throws:

RemoteException - in the event of remote object failure.

getItems

List getItems()
       throws ServiceException,
RemoteException

List all items in the folder. These are only the individual items. Subfolders will be returned separately.

Returns:

A List of MetadataInterface objects in this folder.

Throws:

ServiceException - if a repository error occurs.

RemoteException - in the event of remote object failure.

getItemsByType

List getItemsByType(String metadataType)
             throws ServiceException,
RemoteException

Get a list of items in the folder of a specific type.

Parameters:

metadataType - A String that will match the output from the object's getType method.

Returns:

A List of MetadataInterface objects whose getType() method returns the string specified by metadataType.

Throws:

ServiceException - if a repository error occurs.

RemoteException - in the event of remote object failure.

getItemsByClass

List getItemsByClass(Class itemClass)
              throws ServiceException,
RemoteException

List the items in the folder that match the Class passed in as a parameter. This Class should be a subclass of MetadataInterface.

Parameters:

itemClass - The Class used to filter the folder objects to return.

Returns:

A List of MetadataInterface objects that match the itemClass.

Throws:

ServiceException - If a repository error occurs.

RemoteException - in the event of remote object failure.

getItem

MetadataInterface getItem(String name)
                   throws ServiceException,
RemoteException

Get a named item from the folder. With only a name, we can't guarantee that the object coming back will be the one the user wants. Even if we ask for a type, name collisions can occur.

Parameters:

name - The name of the object to return.

Returns:

A MetadataInterface object matching name.

Throws:

ServiceException - if a repository error occurs.

RemoteException - in the event of remote object failure.

getPublicTypeItem

MetadataInterface getPublicTypeItem(String name,
 String type)
                             throws ServiceException,
RemoteException

Find an item in this Folder with the given name and type. This will use search to get the item, so it will always go to the server to find the object. The upside is, it will always get a fresh copy of the object. The downside is, no caching applies. This doesn't populate the folders items, and will always go to the server.

Parameters:

name - The name of the object to find. If null, a null is returned.

type - The public type name of the object type. If this is null, a null is returned. If the type is not recognized as a public type, a ServiceException will be thrown

Returns:

The matching item in this folder, or null if none exists.

Throws:

ServiceException - if the type is not a public type, or if a repository error occurs.

RemoteException - in the event of remote object failure.

getItemByType

MetadataInterface getItemByType(String name,
 String metadataType)
                         throws ServiceException,
RemoteException

Get a named item from the folder. With only a name, we can't guarantee that the object coming back will be the one the user wants. Even if we ask for a type, name collisions can occur.

Parameters:

name - The name of the object to return.

metadataType - The type of object to return.

Returns:

A MetadataInterface object that matches the name and type requested, or null if none is found.

Throws:

ServiceException - if a repository error occurs.

RemoteException - in the event of remote object failure.

getItemByClass

MetadataInterface getItemByClass(String name,
 Class itemClass)
                          throws ServiceException,
RemoteException

Get a named item from the folder. It must match both the name and the Class provided. If no Class is provided on the call, the first object matching the name is retuned. If no match is found, null is returned.

Parameters:

name - The name of the object to return.

itemClass - The Class of the object to return.

Returns:

A MetadataInterface object in the folder that matches the name and Class requested.

Throws:

ServiceException - if a repository error occurs.

RemoteException - in the event of remote object failure.

getSubfolders

List getSubfolders()
            throws ServiceException,
RemoteException

Get all the folders immediately below this one in the hiearchy.

Returns:

A List of FolderInterface objects that are members of this folder.

Throws:

ServiceException - if a repository error occurs.

RemoteException - in the event of remote object failure.

FolderInterface getSubfolder(String name)
                      throws ServiceException,
RemoteException

Get a named subfolder.

Parameters:

name - The name of the folder to return.

Returns:

A FolderInterface object with the name requested, or null if it doesn't exist.

Throws:

ServiceException - if a repository error occurs.

RemoteException - in the event of remote object failure.

addItem

The new metadata object.
