### Question:
ImmutableElectricObject { Variable[] arrayWithRenamedIds(IdMapper idMapper) { return arrayWithRenamedIds(vars, idMapper); } ImmutableElectricObject(Variable[] vars, int flags); Variable getVar(Variable.Key key); T getVarValue(Variable.Key key, Class type); Iterator<Variable> getVariables(); Variable[] toVariableArray(); int getNumVariables(); Variable getVar(int varIndex); int searchVar(Variable.Key key); abstract int hashCodeExceptVariables(); abstract boolean equalsExceptVariables(ImmutableElectricObject o); boolean equalsVariables(ImmutableElectricObject o); final int flags; }### Answer:
@Test public void testArrayWithRenamedIds() { System.out.println("arrayWithRenamedIds"); IdMapper idMapper = new IdMapper(); assertSame(obj_Aa.getVars(), obj_Aa.arrayWithRenamedIds(idMapper)); }
