glua-RobustClass

A flexible, performant, solid, and practical class system for GLua.

What's the point?

We already have powerful enough Lua metatables. So, what's the purpose of it?

It serves as a tool that amplifies their functionality and streamlines the work process with them.

Features

• Highly performant table-access concerning the object's values, its class's values, its base classes' values
    No function in __index-metafield is used
  

  Demo

   local BasePanel = robustclass( 'BasePanel' )
   do
  
   	BasePanel.BaseWidth = 64
   	BasePanel.BaseHeight = 24
  
   	function BasePanel:BasePanel()
  
   		self.x, self.y = 0, 0
   		self.w, self.h = BasePanel.BaseWidth, BasePanel.BaseHeight
  
   	end
  
   end
  
   local ButtonBase = robustclass( 'ButtonBase : BasePanel' )
   local Button = robustclass( 'Button : ButtonBase' )
  
   local BasicLabel = robustclass( 'BasicLabel : Button' )
  
   print( Format( 'BasicLabel.BaseWidth => %s', BasicLabel.BaseWidth ) )
  
   local Label = BasicLabel()
   print( Format( 'Label.w => %s', Label.w ) )

  

• Recursive construction & destruction of an object
  

  Demo

   local BasePanel = robustclass( 'BasePanel' )
   do
  
   	function BasePanel:BasePanel() print( 'BasePanel\'s constructor called' ) end
   	function BasePanel:_BasePanel() print( 'BasePanel\'s destructor called' ) end
  
   end
  
   local ButtonBase = robustclass( 'ButtonBase : BasePanel' )
   do
  
   	function ButtonBase:ButtonBase() print( 'ButtonBase\'s constructor called' ) end
  
   end
  
   local Button = robustclass( 'Button : ButtonBase' )
   do
  
   	function Button:Button() print( 'Button\'s constructor called' ) end
  
   end
  
   local BasicLabel = robustclass( 'BasicLabel : Button' )
   do
  
   	function BasicLabel:BasicLabel() print( 'BasicLabel\'s constructor called' ) end
  
   end
  
   local Label = BasicLabel()
   print( Label )
  
   robustclass.Delete( Label )

  

• Possibility of adjusting/overriding the default creation/deletion action
    See more at the docs.

• Multiple inheritance
  

  Demo

   local BasePanel = robustclass( 'BasePanel' )
   do
  
   	BasePanel.BaseWidth = 64
   	BasePanel.BaseHeight = 24
  
   	function BasePanel:BasePanel()
  
   		self.x, self.y = 0, 0
   		self.w, self.h = BasePanel.BaseWidth, BasePanel.BaseHeight
  
   	end
  
   end
  
   local BasicLabel = robustclass( 'BasicLabel : BasePanel' )
   do
  
   	function BasicLabel:BasicLabel()
  
   		self.text = 'Lorem ipsum'
  
   	end
  
   end
  
   local ButtonBase = robustclass( 'ButtonBase : BasePanel' )
   local Button = robustclass( 'Button : ButtonBase, BasicLabel' )
  
   local ContextActions = robustclass( 'ContextActions' )
   do
  
   	function ContextActions:ContextActions()
  
   		self.Actions = {}
  
   	end
  
   end
  
   local AdvancedLabel = robustclass( 'AdvancedLabel : BasicLabel, ButtonBase, ContextActions' )
  
   local pnlLabel = AdvancedLabel()
   print( pnlLabel.text, pnlLabel.Actions )
