Helper classes to map InfluxDB QueryResult object to POJO.

How to use it

Supposing that you have a measurement CPU:

> INSERT cpu,host=serverA,region=us_west idle=0.64,happydevop=false,uptimesecs=123456789i
>
> select * from cpu
name: cpu
time                           happydevop host    idle region  uptimesecs
----                           ---------- ----    ---- ------  ----------
2017-06-20T15:32:46.202829088Z false      serverA 0.64 us_west 123456789

And the following tag keys:

> show tag keys from cpu
name: cpu
tagKey
------
host
region

1. Create a POJO to represent your measurement. For example:

public class Cpu {
    private Instant time;
    private String hostname;
    private String region;
    private Double idle;
    private Boolean happydevop;
    private Long uptimeSecs;
    // getters (and setters if you need)
}

2. Add @Measurement and @Column annotations:

@Measurement(name = "cpu")
public class Cpu {
    @Column(name = "time")
    private Instant time;
    @Column(name = "host", tag = true)
    private String hostname;
    @Column(name = "region", tag = true)
    private String region;
    @Column(name = "idle")
    private Double idle;
    @Column(name = "happydevop")
    private Boolean happydevop;
    @Column(name = "uptimesecs")
    private Long uptimeSecs;
    // getters (and setters if you need)
}

3. Call InfluxDBResultMapper.toPOJO(...) to map the QueryResult to your POJO:

InfluxDB influxDB = InfluxDBFactory.connect("http://localhost:8086", "root", "root");
String dbName = "myTimeseries";
QueryResult queryResult = influxDB.query(new Query("SELECT * FROM cpu", dbName));

InfluxResultMapper resultMapper = new InfluxResultMapper(); // or maybe declared as static final
List<Cpu> cpuList = resultMapper.toPOJO(queryResult, Cpu.class);
