Base (Root) RTTI Type

[Hafedh TRIMECHE 1]

Hello,

 

Is there a function GetBaseType which returns the Base Type of a sub-type?

 

type

  TCustomDateTime = type TDateTime;

GetBaseType(TypeInfo(TCustomDateTime)) would return TypeInfo(TDateTime).

 

Best regards.

for Class and Interface, for example:

• see in Help System:  System.Rtti.TRttiType.BaseType
  • The value of BaseType depends on the actual reflected type. In the case of types that support inheritance (such as classes or interfaces), BaseType represents the ancestor. For all other cases, BaseType simply returns nil.
• using RTTI to get info: https://stackoverflow.com/questions/7836880/how-can-i-distinguish-tdatetime-properties-from-double-properties-with-rtti  <--- I think that answer you!
