| /** |
| * for XCAS and XMI deserialization, need to remember |
| * what's being added to the indexes and/or removed, because |
| * the actual FSs are not yet "fixed up" (adjusted for |
| * reference id's → actual addresses, including the sofa refs) |
| * for non-delta updates. |
| * |
| * Workaround (2014) is to remember the information, and do the |
| * adds / removes after the fixups. |
| * |
| * The information to be remembered is: |
| * 1) the View reference (a ref to the FSIndexRepository |
| * a) for each of these, the list of FSaddrs to be added or removed |
| * |
| * The list of FSaddrs ought to be a set with no duplicates, but because |
| * it could be sourced from a hand-edited source, we cannot depend on that |
| * so we store the list as a "set" to prevent duplicates. |
| * |
| * The remove operation only removes 1 instance (in case multiple instances |
| * of the same FS are in the indexes). |
| * |
| * Currently only used by XMI deserialization |
| * |
| * Constructor - done by caller - constructs IdentityHashMap |
