◆ fieldsEqual()

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

overridevirtual

Additional check for whether fields of derived iterators are equal.

Helps make overriding the == operator easy.

Reimplemented from nav_grid_iterators::BaseIterator< PolygonOutline >.

Definition at line 129 of file polygon_outline.cpp.

◆ increment()

void nav_grid_iterators::PolygonOutline::increment ( )

overridevirtual

Increase the iterator to the next element.

Implements nav_grid_iterators::BaseIterator< PolygonOutline >.

Definition at line 113 of file polygon_outline.cpp.

◆ loadSide()

void nav_grid_iterators::PolygonOutline::loadSide ( )

protected

Given a new side index, loads the internal iterator. If there are no valid values in the internal iterator, increases the side index.

Definition at line 79 of file polygon_outline.cpp.

◆ operator=()

PolygonOutline & nav_grid_iterators::PolygonOutline::operator= ( const PolygonOutline & other )

Assignment Operator Required to ensure unique_ptr is set properly.
