java.lang.Object
org.apache.lucene.util.SPIClassIterator<S>
- All Implemented Interfaces:
- Iterator<Class<? extends S>>
public final class SPIClassIterator<S>
- extends Object
- implements Iterator<Class<? extends S>>
Helper class for loading SPI classes from classpath (META-INF files).
This is a light impl of ServiceLoader
but is guaranteed to
be bug-free regarding classpath order and does not instantiate or initialize
the classes found.
- NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

- Utility method to check if some class loader is a (grand-)parent of or the same as another one.
This means the child will be able to load all classes from the parent, too.
