Typedef Documentation

vtkCompositeArray

template<typename T>

using vtkCompositeArray

Initial value:

 
  vtkImplicitArray<vtkCompositeImplicitBackend<T>, vtkArrayTypes::VTK_COMPOSITE_ARRAY>

A utility alias for concatenating arrays into an implicit array.

In order to be usefully included in the dispatchers, these arrays need to be instantiated at the vtk library compile time.

An example of potential usage

vtkNew<vtkIntArray> leftArr;
leftArr->SetNumberOfComponents(1);
leftArr->SetNumberOfTuples(1);
leftArr->SetValue(0, 0);
vtkNew<vtkIntArray> rightArr;
rightArr->SetNumberOfComponents(1);
rightArr->SetNumberOfTuples(1);
rightArr->SetValue(0, 1);
std::vector<vtkDataArray*> arrays({leftArr, rightArr});
vtkNew<vtkCompositeArray<int>> compositeArr;
compositeArr->SetBackend(std::make_shared<vtkCompositeImplicitBackend<int>>(arrays));
compositeArr->SetNumberOfComponents(1);
compositeArr->SetNumberOfTuples(2);
CHECK(compositArr->GetValue(1) == 1);
