bindingtable

lua实现的简单数据绑定模型

• 单向绑定
• 一对多绑定
• 支持单次绑定
• 占不支持内嵌table 例如 data = {id = 'mainlei',pos = {x=0,y=0}} data.pos.x,data.pos.y目前无法被绑定，可以自己手动将pos转换为bindingtable

Example：

local bindingtable =  require("bindingtable")

local data = bindingtable.create({x = 0,y = 0})

local tag = bindingtable.watch(data,"x",function ( value_new ,value_old, key)
    print(value_new,value_old,key)
end)


bindingtable.watchonce(data,"y",function ( value_new ,value_old, key)
    print(value_new, value_old, key)
end)

data.x = 10
data.y = 9

data.x = 11
data.y = 110
bindingtable.unwatch(data,"x",tag)
data.x = 0
