Example 1 with Patterns

use of javaslang.match.annotation.Patterns in project javaslang by javaslang.

the class PatternsProcessor method transform.

// Verify correct usage of annotations @Patterns and @Unapply
private Set<ClassModel> transform(Set<TypeElement> typeElements) {
    final Set<ClassModel> classModels = new HashSet<>();
