New Revision: 3013
Modified:
trunk/src/linearref/LinearIterator.cpp
Log:
Throw an exception on first non-linestring component, rather than segfaulting la
ter... (might be better to refuse non-lineal even earlier, but this way we *migh
* be supporting collections with only linestrings)
Modified: trunk/src/linearref/LinearIterator.cpp
