◆ operator*()

const EntityHandle& moab::Range::const_reverse_iterator::operator* ( ) const
inline

dereference that value this iterator points to returns a const reference

631  }

◆ operator+=()

const_reverse_iterator& moab::Range::const_reverse_iterator::operator+= ( EntityID  step)
inline

Advance iterator specified amount. Potentially O(n), but typically better. Always more efficient than calling operator++ step times.

Definition at line 649 of file Range.hpp.

650  {
651  myIter -= step;
652  return *this;

644  }

◆ operator-=()

const_reverse_iterator& moab::Range::const_reverse_iterator::operator-= ( EntityID  step)
inline

Regress iterator specified amount. Potentially O(n), but typically better. Always more efficient than calling operator-- step times.
