Package org.das2.dataset Description

Provides classes and interfaces for combining Datums into structured DataSets, and operators for working with DataSets. The DataSet interface is the base for all DataSets, which all contain a set of monotonically-increasing xtags. DataSets also contain a set of arbitary properties, which are String->Object mappings. These are used to store metadata such as axis labels. DataSets can have auxiliary "planes" attached to them. This mechanism was first introduced as a means to keep track of the weights after averaging, but we also use them for peaks-and-averages plots and orbits.

DataSetDescriptors are used to provide access to datasets that are parametric over a long interval (generally time), such as Voyager 1 power spectrum. Clients request data from a DataSetDescriptor for a given time interval and resolution. The base class DataSetDescriptor is abstract and implements DataSet caching.

Rebinners are DataSet operators that rebin data to a precisely-controlled set of X and Y tags. Various methods for rebinning data such as bin averaging and nearest neighbor sampling are provided.

Lastly, objects for caching datasets are provided.
