Concrete methods
Build an appropriate <code>Geometry</code>, <code>MultiGeometry</code>, or <code>GeometryCollection</code> to contain the <code>Geometry</code>s in it. For example:<br>
Build an appropriate <code>Geometry</code>, <code>MultiGeometry</code>, or <code>GeometryCollection</code> to contain the <code>Geometry</code>s in it. For example:<br>
-
If <code>geomList</code> contains a single <code>Polygon</code>, the <code>Polygon</code> is returned.
-
If <code>geomList</code> contains several <code>Polygon</code>s, a <code>MultiPolygon</code> is returned.
-
If <code>geomList</code> contains some <code>Polygon</code>s and some <code>LineString</code>s, a <code>GeometryCollection</code> is returned.
-
If <code>geomList</code> is empty, an empty <code>GeometryCollection</code> 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.
- Value Params
- geomList

Creates a deep copy of the input {link Geometry}. The {link CoordinateSequenceFactory} defined for this factory is used to copy the {link CoordinateSequence}s of the input geometry.
This is a convenient way to change the <tt>CoordinateSequence</tt> used to represent a geometry, or to change the factory used for a geometry.
{link Geometry#copy()} can also be used to make a deep copy, but it does not allow changing the CoordinateSequence type.
