Method Detail

copyChannelProperties

public static void copyChannelProperties(ChannelIF sourceChan,
                                         ChannelIF updChan)

Copies all the top level properties from sourceChan into this updChan. Convience method to update basic channel properties (like title and description) in one call. Important: Location and Format is unchanged by this operation. TODO: Tricky. There is a bug here that has to be fixed. Channel Properties which are actually pointers to other objects (e.g. Cloud) cannot be simply copied because during channel and item parsing, we first parse the stream into a basic (e.g. impl.basic.Cloud) object, which then gets subsequently copied by this method into a persistent (e.g. impl.hibernate.Cloud) object. I think the solution to this is to pass a ChannelBuilder into this method which is used to create the right type of duplicates of the objects instead of just copying the references. For now I will be skipping those. A similar kind of problem probably exists when copying item properties.

copyItemProperties

public static void copyItemProperties(ItemIF src,
                                      ItemIF dest)

Analogous function to copy all the properties of an item to another one.

Parameters:

src - - Source ItemIF

dest - - Destination ItemIF
