[geos-devel] Linestring intersection on vertex

Hi everyone

I'd like to know if there is an efficient way to know if two linestrings intersect at a common vertex. What I'm currently doing is like this :

-          Test if linestrings intersect

-          Is the intersection a point ?

-          If it's a point, is it a vertex of both linestrings (which is the slow part for long linestrings) ?

Do you know a faster way to achieve this result ?

Many thanks
