private static final class RequestHandlers.LazyRequestHandlerWrapper extends java.lang.Object implements SolrRequestHandler, SolrInfoMBean
LazyRequestHandlerWrapper wraps any SolrRequestHandler
.
Rather then instanciate and initalize the handler on startup, this wrapper waits
until it is actually called. This should only be used for handlers that are
unlikely to be used in the normal lifecycle.
You can enable lazy loading in solrconfig.xml using:
<requestHandler name="..." class="..." startup="lazy">
...
</requestHandler>
This is a private class - if there is a real need for it to be public, it could
move
