Detailed Description

Iterator class to iterate through a circular area of the map with a spiral.

Definition at line 22 of file SpiralIterator.hpp.


Constructor & Destructor Documentation

grid_map::SpiralIterator::SpiralIterator ( const grid_map::GridMap gridMap,
const Eigen::Vector2d &  center,
const double  radius 
)

Constructor.

Parameters:
gridMapthe grid map to iterate on.
centerthe position of the circle center.
radiusthe radius of the circle.

Definition at line 18 of file SpiralIterator.cpp.


Member Function Documentation

Uses the current distance to get the points of a ring around the center.

Definition at line 84 of file SpiralIterator.cpp.

Gets the radius of current ring that is iterated through.

Returns:
radius of the current ring that is used for iteration.

Definition at line 116 of file SpiralIterator.cpp.

bool grid_map::SpiralIterator::isInside ( const Index  index) const [private]

Check if index is inside the circle.

Returns:
true if inside, false otherwise.

Definition at line 76 of file SpiralIterator.cpp.

Indicates if iterator is past end.

Returns:
true if iterator is out of scope, false if end has not been reached.

Definition at line 71 of file SpiralIterator.cpp.

bool grid_map::SpiralIterator::operator!= ( const SpiralIterator other) const

Compare to another iterator.

Returns:
whether the current iterator points to a different address than the other one.

Definition at line 54 of file SpiralIterator.cpp.

const Eigen::Array2i & grid_map::SpiralIterator::operator* ( ) const

Dereference the iterator with const.

Returns:
the value to which the iterator is pointing.

Definition at line 59 of file SpiralIterator.cpp.

SpiralIterator & grid_map::SpiralIterator::operator++ ( )

Increase the iterator to the next element.

Returns:
a reference to the updated iterator.

Definition at line 64 of file SpiralIterator.cpp.

SpiralIterator & grid_map::SpiralIterator::operator= ( const SpiralIterator other)

Assignment operator.

Parameters:
iteratorthe iterator to copy data from.
Returns:
a reference to *this.

Definition at line 38 of file SpiralIterator.cpp.
