Detailed Description

template<class TCondition, class TType = void>
struct itk::DisableIf< TCondition, TType >

simplified way to dispose of disable_if.

Template Parameters

TCondition	Condition type. It's expected to provide a boolean value through its Value member.
TType	Type to return when the TCondition is (a) false (type).

This overload automatically fetches TCondition value. However, beware, it won't work with standard C++ traits or boost traits. Indeed, this enable_if overload expects the value to follow UpperCamelCase ITK naming policy instead of the standard snake_case policy.

Example:

template< typename TType>
  typename DisableIf<
    mpl::Not_<IsSame<TType, typename NumericTraits<TType>::ValueType>>,
    TType >::Type
GetComponent(const TType pix,
             unsigned int itkNotUsed( idx ) ) const
{
  return pix;
}
