Class WeakTable

java.lang.Object

com.prineside.luaj.WeakTable

public class WeakTable
extends Object

Subclass of LuaTable that provides weak key and weak value semantics.

Normally these are not created directly, but indirectly when changing the mode of a LuaTable as lua script executes.

However, calling the constructors directly when weak tables are required from Java will reduce overhead.
