Accessor for items that are STL compatible vectors.
It encapsulates access to a vector's access functionality.
Usage:
#include <vigra/accessor.hxx>
 Namespace: vigra
The accessor has two modes of operation:
Access the vector's iterator via the begin() and end() functions:
operator[] ): Required Interface:
| typedef VECTOR::value_type component_type | 
the vector's value_type
| typedef VectorElementAccessor<VectorAccessor<VECTOR> > ElementAccessor | 
the vector element accessor associated with this vector accessor (see VectorElementAccessor)
| component_type const& getComponent | ( | ITERATOR const & | i, | 
| int | idx | ||
| ) | const | 
Read the component data at given vector index at given iterator position
| void setComponent | ( | V const & | value, | 
| ITERATOR const & | i, | ||
| int | idx | ||
| ) | const | 
Set the component data at given vector index at given iterator position. The type V of the passed in value is automatically converted to component_type. In case of a conversion floating point -> integral this includes rounding and clipping. 
| component_type const& getComponent | ( | ITERATOR const & | i, | 
| OFFSET const & | diff, | ||
| int | idx | ||
| ) | const | 
Read the component data at given vector index at an offset of given iterator position
| void setComponent | ( | V const & | value, | 
| ITERATOR const & | i, | ||
| OFFSET const & | diff, | ||
| int | idx | ||
| ) | const | 
Set the component data at given vector index at an offset of given iterator position. The type V of the passed in value is automatically converted to component_type. In case of a conversion floating point -> integral this includes rounding and clipping.
