Class SparseFloatDataSiTest

java.lang.Object
org.djunits.vecmat.storage.SparseFloatDataSiTest
public class SparseFloatDataSiTest extends Object
Unit tests for SparseFloatDataSi.

Achieves full branch and method coverage, including:

  • All constructors
  • Validation of nulls, bounds, ragged matrices, and index invariants
  • Sparse generation via all storeSparse(...) overloads
  • Binary-search paths in get()
  • All DataGrid default methods (getRowArray, getColArray)
  • copy(), instantiateNew(), cardinality()
  • SI conversion using Length
  • equals and hashCode
