Detailed Description

Implements Bresenham's line algorithm with a square sliding window.

This class provides a way to iterate over a line while considering a sliding window to enable line width.

Member Function Documentation

◆ Init()

static State olp::geo::detail::LineEvaluator::Init ( const TileKey  start_tile,
const TileKey  end_tile,
const int32_t  sliding_window_half_size 
)
inlinestatic

Initializes the line state between two tiles.

Parameters
start_tileThe starting tile.
end_tileThe ending tile.
sliding_window_half_sizeThe half-size of the sliding window.
Returns
The initialized line state.

◆ Iterate()

static bool olp::geo::detail::LineEvaluator::Iterate ( State &  state)
inlinestatic

Iterates the state towards the end of the line.

Parameters
stateThe current state of the line traversal.
Returns
True if the iteration continues, false if it ends.

◆ Value()

static TileKey olp::geo::detail::LineEvaluator::Value ( const State &  state)
inlinestatic

Evaluates the current tile key from the given state.

Parameters
stateThe current state of the line traversal.
Returns
The tile key corresponding to the current position.
