WeakTable.WeakSlot(java.lang.Object key, java.lang.Object value, org.luaj.vm2.LuaTable.Slot next)

Method Summary

org.luaj.vm2.LuaTable.Slot	add(org.luaj.vm2.LuaTable.Slot entry) Link the given new entry to this slot.
int	arraykey(int max) Return first entry's key, iff it is an integer between 1 and max, inclusive, or zero otherwise.
protected abstract WeakTable.WeakSlot	copy(org.luaj.vm2.LuaTable.Slot next)
org.luaj.vm2.LuaTable.StrongSlot	find(LuaValue key) Compare given key with first()'s key; return first() if equal.
org.luaj.vm2.LuaTable.StrongSlot	first() Return first Entry, if still present, or null.
boolean	keyeq(LuaValue key) Compare given key with first()'s key; return true if equal.
abstract int	keyindex(int hashMask) Return hash{pow2,mod}( first().key().hashCode(), sizeMask )
org.luaj.vm2.LuaTable.Slot	relink(org.luaj.vm2.LuaTable.Slot rest) Return a Slot with the same first key and value (if still present) and rest() equal to rest.
org.luaj.vm2.LuaTable.Slot	remove(org.luaj.vm2.LuaTable.StrongSlot target) Return a Slot with the given value set to nil; must not return null for next() to behave correctly.
org.luaj.vm2.LuaTable.Slot	rest() Return rest of elements
org.luaj.vm2.LuaTable.Slot	set(org.luaj.vm2.LuaTable.StrongSlot target, LuaValue value) Set the value of this Slot's first Entry, if possible, or return a new Slot whose first entry has the given value.
