Package org.apache.maven.internal.impl.model

Class Result<T>

java.lang.Object
org.apache.maven.internal.impl.model.Result<T>
Type Parameters:
T - the model type
public class Result<T> extends Object
There are various forms of results that are represented by this class:
  1. success - in which case only the model field is set
  2. success with warnings - model field + non-error model problems
  3. error - no model, but diagnostics
  4. error - (partial) model and diagnostics
Could encode these variants as subclasses, but kept in one for now
