Method Detail

read

public void read(IDevTree tree,
                 String path)
          throws IllegalArgumentException,
                 IOException

Populate folder or create AIDA object in the tree. If some folders along the path are missing, IOnDemandStore must create them using ITree "mkdirs(path)" method. Tree relies on Store calling IDevTree.hasBeenFilled(String path) method, to let Tree know that a particular folder has been filled.

Parameters:

path - The path to the diretory which is to be filled.

Throws:

IllegalArgumentException - If the path does not exist, or if it is not a directory.

IOException - If there are problems reading from the Store
