Description copied from interface:SlotMap
Replace "slot" with a new slot. This is used to change slot types.
-
add
public void add(Slot newSlot)
Description copied from interface:SlotMap
Insert a new slot to the map. Both "name" and "indexOrHash" must be populated. Note that ScriptableObject generally adds slots via the "modify" method.

private void insertNewSlot(Slot newSlot)
-
remove
public void remove(java.lang.Object key, int index)
Description copied from interface:SlotMap
Remove the slot at either "key" or "index".
-
addKnownAbsentSlot
private static void addKnownAbsentSlot(Slot[] addSlots, Slot slot)
