List of buildGeometry() Examples

Examples of buildGeometry()

com.vividsolutions.jts.geom.GeometryFactory.buildGeometry()
Build an appropriate Geometry, MultiGeometry, or GeometryCollection to contain the Geometrys in it. For example:
- If geomList contains a single Polygon, the Polygon is returned.
- If geomList contains several Polygons, a MultiPolygon is returned.
- If geomList contains some Polygons and some LineStrings, a GeometryCollection is returned.
- If geomList is empty, an empty GeometryCollection is returned
Note that this method does not "flatten" Geometries in the input, and hence if any MultiGeometries are contained in the input a GeometryCollection containing them will be returned. @param geomList the Geometrys to combine @return a Geometry of the "smallest", "mosttype-specific" class that can contain the elements of geomList .
