| 360 | Changes in 2.0.0
|
|---|
| 361 |
|
|---|
| 362 | - CoordinateList renamed to CoordinateSequence, BasicCoordinateList
|
|---|
| 363 | renamed to DefaultCoordinateSequence to reflect JTS changes.
|
|---|
| 364 | DefaultCoordinateSequenceFactory and CoordinateSequenceFactory
|
|---|
| 365 | got same interface as JTS.
|
|---|
| 366 | - Added geos/version.h defining versioning infos
|
|---|
| 367 | - Added geos.h for quick inclusion. It will include geos/geom.h,
|
|---|
| 368 | new geos/version.h, geos/util.h geos/io.h and geos/unload.h
|
|---|
| 369 | (geometry input/output, exceptions, operations).
|
|---|
| 370 | - Added a geos::version() function showing GEOS and equivalent
|
|---|
| 371 | JTS versions as strings.
|
|---|
| 372 | - All geometry constructors take ownership of given arguments.
|
|---|
| 373 | GeometryFactory provides pass-by-reference geometry creators
|
|---|
| 374 | to take care of a deep-copy.
|
|---|
| 375 | - GeometryFactory::createMultiPoint(const CoordinateList *)
|
|---|
| 376 | has been renamed to
|
|---|
| 377 | GeometryFactory::createMultiPoint(const CoordinateList &)
|
|---|
| 378 | to reflect copy semantic
|
|---|
| 379 | - GeometryFactory: EMPTY geometry creation do now have their
|
|---|
| 380 | own constructors taking no arguments.
|
|---|
| 381 | - Geometry constructors taking PrecisionModel and SRID have
|
|---|
| 382 | been dropped. You have to use GeometryFactory instead.
|
|---|
| 383 | - WKTWriter default constructor has been dropped. You need
|
|---|
| 384 | to initialize it with an explicit GeometryFactory
