Parameters: spi WHAT is being looked for (an implementation of this class, a default property file related to this class). factory WHO is performing the lookup. prune Determines if ancestors are allowed to be loaded or not.
classLoader
is an
ancestor of any contained class loader.
This can be used to eliminate redundant class loaders
IF all class loaders defer to parent class loaders
before resolving a class.
It may be that this is not always true. Therefore,
this check is not done internally to eliminate
redundant class loaders, but left to the discretion
of the user.Parameters: prune if true, verify that the class loader is not an Ancestor (@see isAncestor) before adding it to our list.
