Modifying the Iterator
######################


The class allows the usage of ``it++`` and ``it--`` and the addition/subtraction of two :ref:`BasisIterators<Iterator>` instances:


.. doxygenfunction:: danceq::internal::BasisIterator::operator++()

.. doxygenfunction:: danceq::internal::BasisIterator::operator--()

.. doxygenfunction:: danceq::internal::BasisIterator::operator+(const uint64_t index_) const

.. doxygenfunction:: danceq::internal::BasisIterator::operator+(const BasisIterator<BasisU1> & basisiterator) const

.. doxygenfunction:: danceq::internal::BasisIterator::operator-(const uint64_t index_) const

.. doxygenfunction:: danceq::internal::BasisIterator::operator-(const BasisIterator<BasisU1> & basisiterator) const



The :ref:`BasisIterator<Iterator>` can be set directly via:


.. doxygenfunction:: danceq::internal::BasisIterator::set_index(uint64_t new_index)

.. doxygenfunction:: danceq::internal::BasisIterator::set_state(typename BasisU1::state_class new_state)
