GtkSharp/generator/Property.cs
Mike Kestner 6d30cf0c3e refactoring to remove substantial code duplication thoughout the generator
2002-05-23  Mike Kestner <mkestner@speakeasy.net>

	* generator/BoxedGen.cs : Update for Static SymbolTable
	* generator/CallbackGen.cs : Use GenBase and Parameters classes
	* generator/CodeGenerator.cs : Update for Static SymbolTable
	* generator/Ctor.cs : code from StructBase using Parameters class
	* generator/EnumGen.cs : Use GenBase
	* generator/GenBase.cs : Abstract Stream Writer creation, stream
	  boilerplate, and common *Name properties
	* generator/IGeneratable.cs : Update for Static SymbolTable
	* generator/InterfaceGen.cs : Use GenBase
	* generator/Method.cs : code from StructBase using Parameters class
	* generator/ObjectGen.cs : Major refactoring. Use GenBase. Build
	  tables of Member generatables at construct time to facilitate
	  future name collision resolution logic.
	* generator/Parameters.cs : new generatable to abstract duplicated
	  parameter parsing logic.
	* generator/Parser.cs : Update for Static SymbolTable
	* generator/Property.cs : code from ObjectGen
	* generator/Signal.cs : code from ObjectGen
	* generator/SignalHandler.cs : Update for Static SymbolTable
	* generator/StructBase.cs : Update for Static SymbolTable
	* generator/StructGen.cs : Update for Static SymbolTable
	* generator/SymbolTable.cs : Make all methods and private members
	  static.  There is no reason to ever have multiple tables.
