Method Detail

listAllObjects

public java.util.Vector listAllObjects(java.lang.String objectType)

Provides a list of ObjectBindings of all objects of the given type that are found in the persistence storage (given the filters set on the persistence manager by the application that set permissions, roots, etc.).

Parameters:

objectType - a string representing the type of the objects that we are looking for

Returns:

a vector of objects (of type ObjectBinding) of a given type null if no objects of this type are found

loadObjectByType

public ObjectBinding loadObjectByType(java.lang.String objectType)

Retrives from the persistence storage an object of a given type. This method is expected to evoke a "Browse" UI that, when closed, will return an object (in the form of ObjectBinding) selected by the user.

Parameters:

objectType - a string representing the type of the object that we are looking for

Returns:

an object retrieved from the persistence storage null if not object matching the given criteria is found

saveObjectByType

public ObjectBinding saveObjectByType(java.lang.String objectType,
StringXMLizable objectToBeSaved)

Saves an object of a given type in the persistence storage. This method is expected to bring a "Browse" UI that will let the user select where the object should be save to and the name of the object.

Parameters:

objectType - a string representing the type of the object that we are saving

objectToBeSaved - an object that we are saving

Returns:

the ObjectBinding representation of the object we saved null if saving failed

deleteObject

public boolean deleteObject(ObjectBinding obj)

Deletes the object from the persistance storage.

Parameters:

obj - an ObjectBinding representing the object to be deleted

Returns:

true if deleting succeed false if deleting failed

getSelectedPath

public java.lang.String getSelectedPath()

Returns the full path of the currently selected object. null if no object is selected.

getSelectedName

public java.lang.String getSelectedName()

Returns the name of the currently selected object. null if no object is selected.
