Example 11 with FileDataStore

use of org.apache.jackrabbit.core.data.FileDataStore in project jackrabbit-oak by apache.

the class LengthCachingDataStoreTest method writeBackNewEntries.

@Test
public void writeBackNewEntries() throws Exception {
    //1. Add some entries to FDS
    FileDataStore fds1 = new FileDataStore();
    File fds1Dir = tempFolder.newFolder();
