* $Log$
* Revision 1.10 2006/03/17 13:24:59 strk
* opOverlay.h header splitted. Reduced header inclusions in operation/overlay implementation files. ElevationMatrixFilter code moved from own file to ElevationMatrix.cpp (ideally a class-private).
*
* Revision 1.9 2006/02/19 19:46:49 strk
* Packages <-> namespaces mapping for most GEOS internal code (uncomplete, but working). Dir-level libs for index/ subdirs.
*
* Revision 1.8 2005/11/21 16:03:20 strk
*
* Coordinate interface change:
* Removed setCoordinate call, use assignment operator
* instead. Provided a compile-time switch to
* make copy ctor and assignment operators non-inline
* to allow for more accurate profiling.
*
* Coordinate copies removal:
* NodeFactory::createNode() takes now a Coordinate reference
* rather then real value. This brings coordinate copies
* in the testLeaksBig.xml test from 654818 to 645991
* (tested in 2.1 branch). In the head branch Coordinate
* copies are 222198.
* Removed useless coordinate copies in ConvexHull
* operations
*
* STL containers heap allocations reduction:
* Converted many containers element from
* pointers to real objects.
* Made some use of .reserve() or size
* initialization when final container size is known
* in advance.
*
* Stateless classes allocations reduction:
* Provided ::instance() function for
* NodeFactories, to avoid allocating
* more then one (they are all
* stateless).
*
* HCoordinate improvements:
* Changed HCoordinate constructor by HCoordinates
* take reference rather then real objects.
* Changed HCoordinate::intersection to avoid
* a new allocation but rather return into a provided
* storage. LineIntersector changed to reflect
* the above change.
*
* Revision 1.7 2004/07/02 13:28:29 strk
* Fixed all #include lines to reflect headers layout change.
* Added client application build tips in README.
*
* Revision 1.6 2003/11/07 01:23:42 pramsey
* Add standard CVS headers licence notices and copyrights to all cpp and h
* files.
