Function documentation

iterator& bn::iunordered_map::iterator::operator++()

Increments the position.

Returns Reference to this.

iterator& bn::iunordered_map::iterator::operator--()

Decrements the position.

Returns Reference to this.

bool operator==(const iterator& a, const iterator& b)

Equal operator.

Parameters
a First iterator to compare.
b Second iterator to compare.
Returns true if the first iterator is equal to the second one, otherwise false.

bool operator!=(const iterator& a, const iterator& b)

Not equal operator.

Parameters
a First iterator to compare.
b Second iterator to compare.
Returns true if the first iterator is not equal to the second one, otherwise false.
