Detailed Description

template<typename VectorType>
class VectorSlice< VectorType >

Filter a range out of any object having a random access operator[] (unsigned int) and a function size() const.

The use of this object is straightforward. It duplicates the random access operator of the VectorType and adds an offset to every index.

Some precautions have to be taken if it is used for a constant vector: the VectorSlice object has to be constant, too. The appropriate initialization sequence is like this:

void f(const std::vector<int>& v)
{
  const VectorSlice<const std::vector<int> > slice(v,...);
  ...
}

◆ ArrayViewType

template<typename VectorType>

using VectorSlice< VectorType >::ArrayViewType = ArrayView<typename std::conditional<std::is_const<VectorType>::value, const typename VectorType::value_type, typename VectorType::value_type>::type>

protected

Alias for the base class name.

Constructor & Destructor Documentation

◆ VectorSlice() [1/2]

template<typename VectorType >

VectorSlice< VectorType >::VectorSlice ( VectorType & v )

inline

Construct a vector slice containing the whole vector. Comes handy, if you did not want to have a slice at all, but the function you call wants it: just put in the vector itself as argument and let this constructor make a slice for you.

Definition at line 119 of file vector_slice.h.

◆ VectorSlice() [2/2]

template<typename VectorType >

VectorSlice< VectorType >::VectorSlice	(	VectorType &	v,
		unsigned int	start,
		unsigned int	length
	)

inline

The real constructor for a vector slice, allowing you to specify the start index and the length of the slice.
