121 * $Log$
122 * Revision 1.6 2006/04/10 13:40:14 strk
123 * Added default ctor for WKTReader (using GeometryFactory's default instance)
124 *
125 * Revision 1.5 2006/04/10 12:05:35 strk
126 * Added inline-replicator implementation files to make sure
127 * functions in .inl files are still available out-of-line.
128 * A side effect is this should fix MingW build.
129 *
130 * Revision 1.4 2006/03/30 09:26:36 strk
131 * minor cleanup
132 *
133 * Revision 1.3 2006/03/24 09:52:41 strk
134 * USE_INLINE => GEOS_INLINE
135 *
136 * Revision 1.2 2006/03/22 16:58:35 strk
137 * Removed (almost) all inclusions of geom.h.
138 * Removed obsoleted .cpp files.
139 * Fixed a bug in WKTReader not using the provided CoordinateSequence
140 * implementation, optimized out some memory allocations.
141 *
142 * Revision 1.1 2006/03/20 18:18:15 strk
143 * io.h header split
144 *
