Constructor Detail

SubsetIteratorWithSize

public SubsetIteratorWithSize(IteratorWithSize i,
                              int offset,
                              int elements)

Constructs an itarator on a subset of the given iterator. The SubsetIterator starts with the offset-element, iterates over elements elements and can return the size

Parameters:

i - the IteratorWithSize to subset

offset - the position of the first element of the subset

elements - the number of elements the subset should have

SubsetIteratorWithSize

public SubsetIteratorWithSize(IteratorWithSize i,
                              int offset)

Constructs an itarator on a subset of the given iterator. The SubsetIteratorWithSize starts with the offset-element and iterates over limit elements and can return its size

Parameters:

i - the IteratorWithSize to subset

offset - the position of the first element of the subset
