## 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,
|  | std::size_t | start1,
|  | MonotoneChain & | mc2,
|  | std::size_t | 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 | ( | const geom::LineSegment & | ,
|  | const geom::LineSegment & |
| ) |  | `[inline, virtual]`

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

Parameters:

  seg1 |
  seg2 |
