Throws:

RemoteException

sync

void sync(List<String> uniqueElementProductTypeNames)
          throws RemoteException

Synchronizes this Cache with the File Manager specified by the setFileManager(URL) method.

Parameters:

uniqueElementProductTypeNames - The List ProductTypes to cache Products from.

Throws:

RemoteException - If there is any error.

sync

void sync(String uniqueElementName,
        List<String> uniqueElementProductTypeNames)
          throws RemoteException

Synchronizes this Cache with the File Manager specified by the setFileManager(URL) method.

Parameters:

uniqueElementName - The met key identifier to use for determining Product existance (if different than "CAS.ProductName").

Throws:

RemoteException - If there is any error.

sync

void sync()
          throws RemoteException

Synchronizes this Cache with the File Manager specified by the setFileManager(URL) method.
