IModel.AddNewModelTo method ¶
Namespace: NextDesign.Core
Description¶
Adds an instance of the specified class with the specified position to the specified field of this instance as the field value. Allows instantiation even if the specified class is abstract and adds it as a field value at the specified position. The specified field must be owned by the class type. Note that no exception is thrown even if the multiplicity upper limit constraint for fields with multiplicity of 2 or more is violated.
The specified class name must be compatible with the field data type. Also, when there is more than one matching class when making a fuzzy match, the instance of the first type-compatible class found is added.
argument¶
| Name | Type | Description |
|---|---|---|
| fieldName | string | Field name Null or empty string cannot be specified. |
| className | string | Class Name Specify the class name or fully qualified name. Null or empty string cannot be specified. |
| direction | string | Additional direction -"first": First -"last": Last -"before": Before -"after": After |
| target | IModel | Additional reference model The additional position is determined based on the model position specified here. When the direction is specified as "first", it is added to the beginning regardless of the reference model. When the direction specification is "last", it is added to the end regardless of the reference model. When the direction is "before", the instance will be added to the specified model position, and when "after", the instance will be added to the next position of the specified model. |
| fuzzy | bool | className argument as the name of the class instead of the fully qualified name. If False, evaluates as the class whose fully qualified name matches className. If True, evaluate as if the class whose class name matches className is specified. The default value is True. |
