AnnotationFinder

java.lang.Object
- org.apache.openejb.util.AnnotationFinder

```
public class AnnotationFinder
extends java.lang.Object
```
ClassFinder searches the classpath of the specified classloader for packages, classes, constructors, methods, or fields with specific annotations. For security reasons ASM is used to find the annotations. Classes are not loaded unless they match the requirements of a called findAnnotated* method. Once loaded, these classes are cached. The getClassesNotLoaded() method can be used immediately after any find* method to get a list of classes which matched the find requirements (i.e. contained the annotation), but were unable to be loaded.

public AnnotationFinder(java.lang.ClassLoader classLoader)
                 throws java.lang.Exception
```
    Creates a ClassFinder that will search the urls in the specified classloader excluding the urls in the classloader's parent. To include the parent classloader, use: new ClassFinder(classLoader, false); To exclude the parent's parent, use: new ClassFinder(classLoader, classLoader.getParent().getParent());
    
    Parameters:
    
    classLoader - source of classes to scan
    
    Throws:
    
    java.lang.Exception - if something goes wrong

public AnnotationFinder(java.lang.ClassLoader classLoader,
                        boolean excludeParent)
                 throws java.lang.Exception
```
    Creates a ClassFinder that will search the urls in the specified classloader.
    
    Parameters:
    
    classLoader - source of classes to scan
    
    excludeParent - Allegedly excludes classes from parent classloader, whatever that might mean
    
    Throws:
    
    java.lang.Exception - if something goes wrong.

                 throws java.lang.Exception
```
    Creates a ClassFinder that will search the urls in the specified classloader excluding the urls in the 'exclude' classloader.
    
    Parameters:
    
    classLoader - source of classes to scan
    
    exclude - source of classes to exclude from scanning
    
    Throws:

- Method Detail
  - getClassesNotLoaded
```
public java.util.List<java.lang.String> getClassesNotLoaded()
```
    Returns a list of classes that could not be loaded in last invoked findAnnotated* method. The list will only contain entries of classes whose byte code matched the requirements of last invoked find* method, but were unable to be loaded and included in the results. The list returned is unmodifiable. Once obtained, the returned list will be a live view of the results from the last findAnnotated* method call. This method is not thread safe.
    
    Returns:
    
    an unmodifiable live view of classes that could not be loaded in previous findAnnotated* call.
