Example 1 with BinaryEntryIterator

use of com.baidu.hugegraph.backend.serializer.BinaryEntryIterator in project incubator-hugegraph by apache.

the class HbaseTable method newEntryIterator.

protected BackendEntryIterator newEntryIterator(Query query, RowIterator rows) {
    return new BinaryEntryIterator<>(rows, query, (entry, row) -> {
        E.checkState(!row.isEmpty(), "Can't parse empty HBase result");
        byte[] id = row.getRow();
        if (entry == null || !Bytes.prefixWith(id, entry.id().asBytes())) {
            HugeType type = query.resultType();
            // NOTE: only support BinaryBackendEntry currently
            entry = new BinaryBackendEntry(type, id, this.enablePartition);
        }
        try {
            this.parseRowColumns(row, entry, query, this.enablePartition);
        } catch (IOException e) {
            throw new BackendException("Failed to read HBase columns", e);
        }
        return entry;
    });
}

Example 2 with BinaryEntryIterator

use of com.baidu.hugegraph.backend.serializer.BinaryEntryIterator in project incubator-hugegraph by apache.

            // NOTE: only support BinaryBackendEntry currently
            entry = new BinaryBackendEntry(type, col.name);
        } else {
            assert !Bytes.equals(entry.id().asBytes(), col.name);
