Class TimeseriesSchema

java.lang.Object

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

All Implemented Interfaces:

Serializable, Comparable<TimeseriesSchema>

public class TimeseriesSchema
extends Object
implements Comparable<TimeseriesSchema>, Serializable

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