GeometryCollection(Geometry[])

Declaration

public GeometryCollection(Geometry[] geometries)

Parameters

Type	Name	Description
Geometry[]	geometries	The `Geometry`s for this `GeometryCollection`, or `null` or an empty array to create the empty point. Elements may be empty `Geometry`s, but not `null`s.

Remarks

For create this Geometry is used a standard GeometryFactory with PrecisionModel == Floating.
