Example 1 with MapBinding

use of org.apache.qpid.server.store.berkeleydb.tuple.MapBinding in project qpid-broker-j by apache.

the class AbstractBDBPreferenceStore method getPreferenceRecords.

private Collection<PreferenceRecord> getPreferenceRecords(final EnvironmentFacade environmentFacade) {
    Collection<PreferenceRecord> records = new LinkedHashSet<>();
    try (Cursor cursor = getPreferencesDb().openCursor(null, null)) {
        DatabaseEntry key = new DatabaseEntry();
        DatabaseEntry value = new DatabaseEntry();
        UUIDTupleBinding keyBinding = UUIDTupleBinding.getInstance();
        MapBinding valueBinding = MapBinding.getInstance();
        while (cursor.getNext(key, value, LockMode.READ_UNCOMMITTED) == OperationStatus.SUCCESS) {
            UUID preferenceId = keyBinding.entryToObject(key);
            Map<String, Object> preferenceAttributes = valueBinding.entryToObject(value);
            PreferenceRecord record = new PreferenceRecordImpl(preferenceId, preferenceAttributes);
            records.add(record);
        }
    } catch (RuntimeException e) {
        throw environmentFacade.handleDatabaseException("Cannot visit preferences", e);
    }
    return records;
}

Example 2 with MapBinding

private void updateOrCreateInternal(final Transaction txn, final Collection<PreferenceRecord> preferenceRecords) {
    Database preferencesDb = getPreferencesDb();
    DatabaseEntry key = new DatabaseEntry();

    MapBinding valueBinding = MapBinding.getInstance();
    for (PreferenceRecord record : preferenceRecords) {
        keyBinding.objectToEntry(record.getId(), key);
        valueBinding.objectToEntry(record.getAttributes(), value);
        OperationStatus status = preferencesDb.put(txn, key, value);
        if (status != OperationStatus.SUCCESS) {
            throw new StoreException(String.format("Error writing preference with id '%s' (status %s)", record.getId(), status.name()));
        }
    }
}
