Class AlignedPath

java.lang.Object

org.apache.iotdb.tsfile.read.common.Path

org.apache.iotdb.commons.path.PartialPath

org.apache.iotdb.commons.path.AlignedPath

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<org.apache.iotdb.tsfile.read.common.Path>

public class AlignedPath
extends PartialPath

VectorPartialPath represents many fullPaths of aligned timeseries. In the AlignedPath, the nodes in PartialPath is deviceId e.g. VectorPartialPath nodes=root.sg1.alignedD1 measurementList=[s1, s2]
