Package org.apache.iotdb.tsfile.write.schema

Class TimeseriesSchema

java.lang.Object

org.apache.iotdb.tsfile.write.schema.TimeseriesSchema

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<TimeseriesSchema>

public class TimeseriesSchema
extends java.lang.Object
implements java.lang.Comparable<TimeseriesSchema>, java.io.Serializable

TimeseriesSchema is like MeasurementSchema, but instead of measurementId, it stores the full path.
