BandwidthHistory (Tor Metrics Library API Documentation)

All Superinterfaces:

java.io.Serializable
```
public interface BandwidthHistory
extends java.io.Serializable
```
Contains the bandwidth history of a relay or bridge.
A bandwidth history is not a descriptor type of its own but usually part of extra-info descriptors (ExtraInfoDescriptor) or server descriptors (ServerDescriptor).

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.util.SortedMap<java.lang.Long,java.lang.Long>`	`getBandwidthValues()`	Return the (possibly empty) bandwidth history with map keys being times in milliseconds since the epoch when intervals end and map values being number of bytes used in the interval, ordered from oldest to newest interval.
`long`	`getHistoryEndMillis()`	Return the time in milliseconds since the epoch when the most recent interval ends.
`long`	`getIntervalLength()`	Return the interval length in seconds.
`java.lang.String`	`getLine()`	Return the original bandwidth history line as contained in the descriptor, possibly prefixed with `"opt "`.
