IModel.AddNewModel Method
Namespace: NextDesign.Core
Description
Adds an instance of the specified class to the specified field of this instance as a field value.
The instance is added as the last element of the field.
Even if the specified class is an abstract class, instantiation is allowed and it is added as the last element of the field.
The specified field must be an owned field of the class type.
No exception is thrown even if the upper multiplicity constraint of a field with multiplicity of 2 or more is violated.
The specified class name must be a type compatible with the data type of the field.
Note that when there are multiple matching classes when performing a fuzzy match, an instance of the first type-compatible class found is added.
