org.elasticsearch.plugins.spi.SPIClassIterator<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.-

isParentClassLoader
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.If caller's codesource doesn't have enough permissions to do the check,
false
is returned (this is fine, because if we get aSecurityException
it is for sure no parent). -
