TypeAttribute

This attribute can be used for the automatic XAML-like serialization by GraphML. It is required for fields and properties that should use attribute-based serialization to inform the reflection engine about the type of the field/property in the meta-data of the class.

const MyClass = yfiles.lang.Class('MyClass', {
    constructor: function() { // the constructor function
      this.$y = 42;
    },

    myProperty: {
      $meta:[yfiles.lang.TypeAttribute(yfiles.lang.Number.$class)],
      get: function() {
        return this.$y;
      },
    },
});
