GeometryCollection (Groovy Documentation)

geoscript.geom.GeometryCollection

```
class GeometryCollection
extends Geometry
```
A GeometryCollection is a heterogenerous collection of other Geometries.
You can create a GeometryCollection by passing in a variable number of Geometries:
```
 def gc = new GeometryCollection(new Point(1,2),new Point(3,4))
 
```
Or you can pass in a List of Geometries:
```
 def pts = [new Point(1,2),new Point(3,4)]
 def gc2 = new GeometryCollection(pts)
 
```

- Constructor Detail
  - GeometryCollection(GeometryCollection geomCollection)
    
    Create a GeometryCollection that wraps a JTS GeometryCollection
    Parameters:
    geomCollection - The JTS GeometryCollection
  - GeometryCollection(Geometry[] geometries)
    
    Create a GeometryCollection from a List of Geometries.
```
 def gc = new GeometryCollection(new Point(1,2),new Point(3,4))
 
```
    Parameters:
    points - A variable List of Points
  - GeometryCollection(java.util.List<Geometry> geometries)
    
    Create a GeometryCollection from a List of Geometries.
```
 def pts = [new Point(1,2),new Point(3,4)]
 def gc2 = new GeometryCollection(pts)
 
```
    Parameters:
    geometries - A List of Geometries
- Method Detail
  - Geometry narrow()
    
    Get a Geometry from this GeometryCollection that is the most type specific as possible. If all of the Geometries are Points, a MultiPoint is returned.
    Returns:
    A Geometry
  - GeometryCollection plus(Geometry geometry)
    
    Add a Geometry to this GeometryCollection to create another GeometryCollection.
    Parameters:
    geometry - The Geometry
    Returns:
    A new GeometryCollection constructed of the Geometries in this GeometryCollection and the new Geometry
  - Geometry slice(java.lang.Integer start, java.lang.Integer end)
    
    Get a subset of Geometries in the GeometryCollection.
    Parameters:
    start - The start index (can be positive or negative)
    end - The end index (can be positive or negative)
    Returns:
    The new Geometry
