## Detailed Description

The action for the internal iterator for performing overlap queries on a MonotoneChain

## Member Function Documentation

virtual void geos::index::chain::MonotoneChainOverlapAction::overlap | ( | MonotoneChain * | mc1,
|  | int | start1,
|  | MonotoneChain * | mc2,
|  | int | start2 |
| ) |  |  | `[virtual]`

This function can be overridden if the original chains are needed

Parameters:

  | start1 | the index of the start of the overlapping segment from mc1
  | start2 | the index of the start of the overlapping segment from mc2

virtual void geos::index::chain::MonotoneChainOverlapAction::overlap | ( | geom::LineSegment * | ,
|  | geom::LineSegment * |  |
| ) |  |  | `[inline, virtual]`

This is a convenience function which can be overridden to obtain the actual line segments which overlap

Parameters:

  | seg1 |
  | seg2 |
