Golang fdb_iterator_get Examples

Example #1

File: iterator.go Project: jchris/indexing

// GetPreAlloc gets the current item (key, metadata, doc body) from the iterator
// but uses the pre-allocated memory for the Doc
func (i *Iterator) GetPreAlloc(rv *Doc) error {
	i.db.Lock()
	defer i.db.Unlock()

	Log.Tracef("fdb_iterator_get call i:%p iter:%v", i, i.iter)
	errNo := C.fdb_iterator_get(i.iter, &rv.doc)
	Log.Tracef("fdb_iterator_get retn i:%p iter:%v doc:%v", i, errNo, i.iter, rv.doc)
	if errNo != RESULT_SUCCESS {
		return Error(errNo)
	}
	return nil
}

Example #2
