示例1: deserialize

import org.apache.hadoop.hbase.util.OrderedBytes; //导入依赖的package包/类
public IndexMetadata deserialize(Result result) {
    byte[] bytes = result.getRow();
    PositionedByteRange buffer = new SimplePositionedByteRange(bytes);
    String label = OrderedBytes.decodeString(buffer);
    String propertyKey = OrderedBytes.decodeString(buffer);
    ElementType type = OrderedBytes.decodeInt8(buffer) == 1 ? ElementType.VERTEX : ElementType.EDGE;
    Cell uniqueCell = result.getColumnLatestCell(Constants.DEFAULT_FAMILY_BYTES, Constants.UNIQUE_BYTES);
    boolean isUnique = ValueUtils.deserialize(CellUtil.cloneValue(uniqueCell));
    Cell stateCell = result.getColumnLatestCell(Constants.DEFAULT_FAMILY_BYTES, Constants.INDEX_STATE_BYTES);
    State state = State.valueOf(ValueUtils.deserialize(CellUtil.cloneValue(stateCell)));
