16:58 Changeset [17446] by dpiringe


  • made interfaces for array/matrix JsonItems and for their VMs aswell (IArrayJsonItem, IArrayJsonItemVM, IMatrixJsonItem, IMatrixJsonItemVM), incl. base classes (ArrayJsonItemBase, ArrayValueVM, MatrixJsonItemBase, MatrixValueVM)
  • changed inheritance structure for already existing array/matrix JsonItems -> they inherit now from new base array/matrix base classes
  • added input elements to configure the size of an matrix or array in JsonItemMultiValueControl (incl. VM binding and validation)
  • splitted file JsonItems.cs into separate files for their corresponding types (IntJsonItems.cs, DoubleJsonItems.cs, BoolJsonItems.cs, StringJsonItem.cs, DateTimeJsonItem.cs)
  • changed location of deserialization of json values from JsonTemplateInstantiator into IJsonItem (implemented in JsonItem and set to virtual, overridden in MatrixJsonItemBase and ArrayJsonItemBase)
  • added new CLI argument StringArgument
  • some little UI improvements (location fixes, anchor fixes, ...)

  • added two new methods in IJsonItem -> FixatePath and LoosenPath to fixate/loosen the path (to enable name changing without effects on path)

  • fixed bug with path for template -> removed usage of method Path.GetDirectoryName, returned wrong results
  • splitted cache for JsonItemConverter into a cache for injection and extraction
  • JsonTemplateInstantiator now uses first item in objects array instead of searching for an object with template name
