The implementation will throw a ClassPathEnumerationError if the retrieved class is not an instance of the expected type.

TThe type of the requested service.
Constructors
public
public
NamedCheckingClassPathServiceEnumerator(String className, Class<?> expectedInstanceOf)
Creates a new enumerator for the given class name and expected type.
Methods
protected Iterable<extends T>
Creates a lazily instantiating Iterable for the found class.
public Class<?>
Gets the class that the service is expected to be an instance of.
public void
The object implements the readExternal method to restore its contents by calling the methods of DataInput for primitive types and readObject for objects, strings and arrays.
public void
The object implements the writeExternal method to save its contents by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings, and arrays.
public NamedCheckingClassPathServiceEnumerator(String className, Class<?> expectedInstanceOf) throws NullPointerException
Creates a new enumerator for the given class name and expected type.
classNameThe class name of the service to look up.
expectedInstanceOfThe expected type to check the service for.
NullPointerExceptionIf any of the arguments are null.
protected Iterable<extends T> createIterable(Class<?> found)
Creates a lazily instantiating Iterable for the found class.
foundThe found class.
The created iterable.
Gets the class that the service is expected to be an instance of.
The class.
