Member Function Documentation

SubGrid nav_grid_iterators::SubGrid::begin ( ) const

overridevirtual

Helper function for range-style iteration Equivalent to the above constructor.

Returns: Iterator representing beginning of the iteration

Implements nav_grid_iterators::BaseIterator< SubGrid >.

Definition at line 68 of file sub_grid.cpp.

SubGrid nav_grid_iterators::SubGrid::end ( ) const

overridevirtual

Helper function for range-style iteration.

Returns: Iterator representing end of the iteration, with an invalid index

Implements nav_grid_iterators::BaseIterator< SubGrid >.

Definition at line 73 of file sub_grid.cpp.

bool nav_grid_iterators::SubGrid::fieldsEqual ( const SubGrid & other )

overridevirtual

Additional check for whether fields of derived iterators are equal.

Helps make overriding the == operator easy.

Reimplemented from nav_grid_iterators::BaseIterator< SubGrid >.

Definition at line 88 of file sub_grid.cpp.

void nav_grid_iterators::SubGrid::increment ( )

overridevirtual

Increase the iterator to the next element.

Implements nav_grid_iterators::BaseIterator< SubGrid >.

Definition at line 78 of file sub_grid.cpp.
