Class LDCacheSailProvider

java.lang.Object

org.apache.marmotta.platform.ldcache.api.ldcache.LDCacheSailProvider

All Implemented Interfaces:

org.apache.marmotta.platform.core.api.triplestore.NotifyingSailProvider, org.apache.marmotta.platform.core.api.triplestore.SailProvider

public abstract class LDCacheSailProvider
extends Object
implements org.apache.marmotta.platform.core.api.triplestore.NotifyingSailProvider

A sail provider service that allows wrapping a transparent Linked Data caching component around the main SAIL. This is the generic superclass for all LDCache backends.
