Examples of org.apache.bookkeeper.client.LedgerEntry

org.apache.bookkeeper.client.LedgerEntry
Ledger entry. Its a simple tuple containing the ledger id, the entry-id, and the entry content.

        // Read the ledger entries to verify that they are all present and
        // correct in the new bookie.
        for (LedgerHandle lh : lhs) {
            Enumeration<LedgerEntry> entries = lh.readEntries(startEntryId, endEntryId);
            while (entries.hasMoreElements()) {
                LedgerEntry entry = entries.nextElement();
                assertTrue(new String(entry.getEntry()).equals("LedgerId: " + entry.getLedgerId() + ", EntryId: "
                           + entry.getEntryId()));
            }
