java.lang.Object
org.djunits.vecmat.storage.SparseDoubleDataSiTest
public class SparseDoubleDataSiTest extends Object
Unit tests for SparseDoubleDataSi.

This test class achieves full branch coverage of all constructors, helper methods, index validation, sparse storage generation, DataGrid default methods, binary-search access path, copy semantics, instantiation operations, equals/hashCode, and all Q-based constructors, including SI-conversion.
