Class ModelAttribute

java.lang.Object
jline.lang.ModelAttribute
All Implemented Interfaces:
Serializable
Direct Known Subclasses:
NetworkAttribute
public class ModelAttribute extends Object implements Serializable
Metadata container held by every Model, twin of the untyped attribute struct of matlab/src/lang/Model.m. MATLAB stores model metadata as dynamically-named struct fields, so the Java twin is a string-keyed map. Subclasses needing a typed container extend this one (NetworkAttribute does), which keeps the covariant getAttribute() override on Network legal.
