Package io.higson.runtime.engine.annotated.scanner

Class AnnotatedObjectsScanner<T>

java.lang.Object

io.higson.runtime.engine.annotated.scanner.AnnotatedObjectsScanner<T>

Type Parameters:

T - type of object to instantiate

public class AnnotatedObjectsScanner<T>
extends Object

Annotation scanner util supporting SmartParam* annotations. It not only scans for annotated objects, but also instantiates them using hints included in annotation. Annotation should define:

• value() - to extract unique code of object
• values() - if same object should be returned multiple times under different names
• instances() - if object should be instantiated with specific constructor args

Also, if scanned annotation is Sortable, it should define order() method.

Since:

0.1.0

Map returned by #getAnnotatedObjects(Class, PackageList) is not ordered, but the key (RepositoryObjectKey) holds all information that can be used for ordering.

getAnnotatedObjects

public Map<RepositoryObjectKey,T> getAnnotatedObjects(Class<? extends Annotation> annotationClass,
 PackageList packagesToScan)

Might throw AnnotationScannerException if any reflective operation fails.

Parameters:

annotationClass - annotation to look for

packagesToScan - packages to scan

Returns:

map of objects

 PackageList packagesToScan)

Scan for classes annotated with given annotation and return instances of those objects (instantiated using default constructor).

Parameters:

annotationClass - annotation to look for

packagesToScan - packages to scan

Returns:

list of type T objects
