org.orekit.data.LazyLoadedDataContext

All Implemented Interfaces:

DataContext

Direct Known Subclasses:

ExceptionalDataContext

public class LazyLoadedDataContext
extends Object
implements DataContext

A data context that aims to match the behavior of Orekit 10.0 regarding auxiliary data. This data context only loads auxiliary data when it is first accessed. It allows data loaders to be added before the data is loaded.

Since:

10.1
