Method Detail

notifyDataspaceAdd

public abstract void notifyDataspaceAdd(DataProxy ds)

notification of being added to a dataspace replica.

Parameters:

ds - The dataspace replica to which this item has been added.

notifyDataspaceUpdate

public abstract void notifyDataspaceUpdate(DataProxy ds,
                                           ItemData oldValue)

notification of being updated in a dataspace replica; called on the new value instance.

Parameters:

ds - The dataspace replica in which this item has been updated.

oldValue - The old value in this dataspace with the same GUID.

notifyDataspaceDelete

public abstract void notifyDataspaceDelete(DataProxy ds)

notification of being deleted from a dataspace replica.

Parameters:

ds - The dataspace replica from which this item has been deleted.

notifyDataspaceReplaced

public abstract void notifyDataspaceReplaced(DataProxy ds)

notification of being updated in a dataspace replica; called on the oldValue instance, after notifyDataspaceUpdate(equip.data.DataProxy, equip.data.ItemData) is called on the new value.

Parameters:

ds - The dataspace replica in which this item has been replaced by the update.

getModuleName

public java.lang.String getModuleName()

IDL-generated helper routine to get module name (currently unimplemented).

Overrides:

getModuleName in class TreeNode

Returns:

name of this class's module
