Method Detail

clear

void clear()
           throws RemoteException

Specifies the URL to the File Manager to connect this Cache to.

Parameters:

fmUrl - The URL of the File Manager to cache Products from.

Throws:

RemoteException

size

int size()
         throws RemoteException

Returns:

The size of the current Product cache.

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").

uniqueElementProductTypeNames - The List of ProductTypes to cache Products from.

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. This method also assumes that the unique element (identified by setUniqueElementName(String) and the List of ProductTypes have also been set appropriate (e.g., by using setUniqueElementProductTypeNames(List).

Throws:

RemoteException - If any error occurs.

setUniqueElementProductTypeNames

void setUniqueElementProductTypeNames(List<String> uniqueElementProductTypeNames)
                                      throws RemoteException

Sets the names of the ProductTypes to cache.

Parameters:

uniqueElementProductTypeNames - A List of java.util.String names of ProductTypes.

Throws:

RemoteException

setUniqueElementName

void setUniqueElementName(String uniqueElementName)
                          throws RemoteException

Sets the name of the met element to use as the identifier of a Product for use in determining whether the Product is in the Cache.

Parameters:

uniqueElementName - The name of the met element used to uniquely identify Products.

Throws:

RemoteException

getFileManagerUrl

URL getFileManagerUrl()
                      throws RemoteException

Gets the URL of the File Manager that this Cache communicates with.
