Description

Many properties of DLx objects are required to be of a certain type (MultiLangString, Transcription, etc.). This utility function provides an abstraction for defining those properties in a way that ensures their values are validated against the proper Model when the value is set. Example usage:

classTextextendsModel{
#title;// private property must be declaredconstructor(){// ensures that the "title" property is always a MultiLangStringModel.defineModelProp(this,`title`,MultiLangString);}}
