getDimension
public int getDimension()Description copied from class:Geometry
Returns the dimension of this geometry. The dimension of a geometry is is the topological dimension of its embedding in the 2-D Euclidean plane. In the JTS spatial model, dimension values are in the set {0,1,2}.Note that this is a different concept to the dimension of the vertex
Coordinate
s. The geometry dimension can never be greater than the coordinate dimension. For example, a 0-dimensional geometry (e.g. a Point) may have a coordinate dimension of 3 (X,Y,Z).- Overrides:
getDimension
in classGeometryCollection
- Returns:
- the topological dimension of this geometry.
- See Also:
-
hasDimension
public boolean hasDimension(int dim) Description copied from class:Geometry
Tests whether an atomic geometry or any element of a collection has the specified dimension. In particular, this can be used with mixed-dimensionGeometryCollection
s to test if they contain an element of the specified dimension.- Overrides:
hasDimension
in classGeometryCollection
- Parameters:
dim
- the dimension to test- Returns:
- true if the geometry has or contains an element with the dimension
- See Also:
-
getBoundaryDimension
public int getBoundaryDimension()Description copied from class:Geometry
Returns the dimension of thisGeometry
s inherent boundary.- Overrides:
getBoundaryDimension
in classGeometryCollection
- Returns:
- the dimension of the boundary of the class implementing this
interface, whether or not this object is the empty geometry. Returns
Dimension.FALSE
if the boundary is the empty geometry.
-
getGeometryType
Description copied from class:Geometry
Returns the name of this Geometry's actual class.- Overrides:
getGeometryType
in classGeometryCollection
- Returns:
- the name of this
Geometry
s actual class
-
getBoundary
Gets the boundary of this geometry. Zero-dimensional geometries have no boundary by definition, so an empty GeometryCollection is returned.- Overrides:
getBoundary
in classGeometryCollection
- Returns:
- an empty GeometryCollection
- See Also:
-
reverse
Description copied from class:GeometryCollection
Creates aGeometryCollection
with every component reversed. The order of the components in the collection are not reversed.- Overrides:
reverse
in classGeometryCollection
- Returns:
- a
GeometryCollection
in the reverse order
-
equalsExact
Description copied from class:Geometry
Returns true if the twoGeometry
s are exactly equal, up to a specified distance tolerance. Two Geometries are exactly equal within a distance tolerance if and only if:- they have the same structure
- they have the same values for their vertices, within the given tolerance distance, in exactly the same order.
GeometryFactory
, theSRID
, or theuserData
fields.To properly test equality between different geometries, it is usually necessary to
Geometry.normalize()
them first.- Overrides:
equalsExact
in classGeometryCollection
- Parameters:
other
- theGeometry
with which to compare thisGeometry
tolerance
- distance at or below which twoCoordinate
s are considered equal- Returns:
true
if this and the otherGeometry
have identical structure and point values, up to the distance tolerance.- See Also:
