LocalBucket

public class LocalBucket extends Object

A bucket represents a time interval over which aggregated data is computed. For example, a bucket can represent user's step count over a 1 hour interval. We allow buckets to be computed by time, where a time bucket can represent a full day, hour, or any other desired interval.

A bucket consists of the following fields:

startTime denotes the start time of the bucket. This field is always present.
endTime denotes the end time of the bucket. This field is always present.
dataSets LocalDataSet for the aggregated LocalDataType requested in the read query over the time interval of this bucket.

Constant Summary

int TYPE_TIME Type constant denoting that bucketing by time is requested.
