Method Summary

Modifier and Type	Method and Description
double	end() End visiting a vector.
void	start(int dimension, int start, int end) Start visiting a vector.
double	visit(int index, double value) Visit one entry of the vector.

Method Detail

start

void start(int dimension,
           int start,
           int end)

Start visiting a vector. This method is called once, before any entry of the vector is visited.

Parameters:

dimension - the size of the vector

start - the index of the first entry to be visited

end - the index of the last entry to be visited (inclusive)

visit

double visit(int index,
             double value)

Visit one entry of the vector.

Parameters:

index - the index of the entry being visited

value - the value of the entry being visited

Returns:

the new value of the entry being visited

end

double end()

End visiting a vector. This method is called once, after all entries of the vector have been visited.

Returns:

the value returned by RealVector.walkInDefaultOrder(RealVectorChangingVisitor), RealVector.walkInDefaultOrder(RealVectorChangingVisitor, int, int), RealVector.walkInOptimizedOrder(RealVectorChangingVisitor) or RealVector.walkInOptimizedOrder(RealVectorChangingVisitor, int, int)
