BaseComponentType

template<typename T >

using vtkm::VecTraits< vtkm::VecC< T > >::BaseComponentType = typename vtkm::VecTraits<ComponentType>::BaseComponentType

Base component type in the vector.

Similar to ComponentType except that for nested vectors (e.g. Vec<Vec<T, M>, N>), it returns the base scalar type at the end of the composition (T in this example).

ComponentType

template<typename T >

using vtkm::VecTraits< vtkm::VecC< T > >::ComponentType = typename VecType::ComponentType

Type of the components in the vector.

If the type is really a scalar, then the component type is the same as the scalar type.

HasMultipleComponents

template<typename T >

using vtkm::VecTraits< vtkm::VecC< T > >::HasMultipleComponents = vtkm::VecTraitsTagMultipleComponents

A tag specifying whether this vector has multiple components (i.e.

is a "real" vector). This tag can be useful for creating specialized functions when a vector is really just a scalar.

The size of a VecC is not known until runtime and can always potentially have multiple components, this is always set to HasMultipleComponents.

IsSizeStatic

template<typename T >

using vtkm::VecTraits< vtkm::VecC< T > >::IsSizeStatic = vtkm::VecTraitsTagSizeVariable

A tag specifying whether the size of this vector is known at compile time.

If set to VecTraitsTagSizeStatic, then NUM_COMPONENTS is set. If set to VecTraitsTagSizeVariable, then the number of components is not known at compile time and must be queried with GetNumberOfComponents.

ReplaceBaseComponentType

template<typename T >

template<typename NewComponentType >

using vtkm::VecTraits< vtkm::VecC< T > >::ReplaceBaseComponentType = vtkm::VecC< typename vtkm::VecTraits<ComponentType>::template ReplaceBaseComponentType<NewComponentType> >

Get a vector of the same type but with a different base component.

This type resolves to another vector with a different base component type. The replacement is recursive for nested types. For example,

VecTraits<Vec<Vec<T, M>, N>::ReplaceComponentType<T2> 

is Vec<Vec<T2, M>, N>.

ReplaceComponentType

template<typename T >

template<typename NewComponentType >

using vtkm::VecTraits< vtkm::VecC< T > >::ReplaceComponentType = vtkm::VecC<NewComponentType>

Get a vector of the same type but with a different component.

This type resolves to another vector with a different component type. For example,

vtkm::VecTraits<vtkm::Vec<T, N>>::ReplaceComponentType<T2> 

is vtkm::Vec<T2, N>. This replacement is not recursive. So

VecTraits<Vec<Vec<T, M>, N>::ReplaceComponentType<T2> 

is vtkm::Vec<T2, N>.

VecType

template<typename T >

using vtkm::VecTraits< vtkm::VecC< T > >::VecType = vtkm::VecC<T>
