## Atom Dict

Atomdict implements a data structure for multi lua state.

You can use it in multi-threads , create one lua state per thread. Atomdict will help you exchange a group data atomic between lua states.

## Quick Example

In data server :

```Lua
  local ad = require "atomdict"
  local handle = ad.new_handle { HP = 100 , Name = "Alice" }

-- Send handle (A integer) to other lua state in other thread
```

In data client :

```Lua
  local ad = require "atomdict"

-- ...

local obj = ad.new(handle) -- get data handle from other lua state before.

-- You can use pairs in this object
  for k,v in pairs(obj) do
    print(k,v)
  end

-- Set obj.Name in local state, others can't see it before call ad.barrier()
  obj.Name = "Bob"

-- put barrier in your main loop of the program
  ad.barrier()
```

## API

### atomdict.new_handle( { key = value(number or string) , ... } , [typename] )

Use a table to init atomdict . You can name the type.
  If you have many objects with the same structure , giving a typename will improve the performance.

It returns an integer handle.

### atomdict.delete_handle( handle )

Delete an atomdict handle. You must delete it before none of the object binding to the handle.

### atomdict.new(handle)

Create an object binding the atomdict handle.
  It returns an userdata like a table.

### atomdict.barrier()

Call barrier to commit atomdict objects that their changes could be seen by others.

### atomdict.dump(object)

Print the object to the stdout. (for debug)

### atomdict.dump_handle(handle) 
  Print the handle to the stdout. (for debug)
