Constructor Detail

Geometry

protected Geometry(GeometryType geometryType,
                   boolean hasZ,
                   boolean hasM)

Constructor

Parameters:

geometryType - geometry type

hasZ - has z

hasM - has m

Method Detail

getGeometryType

public GeometryType getGeometryType()

Get the geometry type

Returns:

geometry type

hasZ

public boolean hasZ()

Does the geometry have z coordinates

Returns:

true if has z coordinates

is3D

public boolean is3D()

Does the geometry have z coordinates

Returns:

true if has z coordinates

See Also:

hasZ()

hasM

public boolean hasM()

Does the geometry have m coordinates

Returns:

true if has m coordinates

isMeasured

public boolean isMeasured()

Does the geometry have m coordinates.

Returns:

true if has m coordinates

See Also:

hasM()

getEnvelope

public GeometryEnvelope getEnvelope()

Get the minimum bounding box for this Geometry

Returns:

geometry envelope

getDimension

public int getDimension()

Get the inherent dimension (0, 1, or 2) for this Geometry

Returns:

dimension

getCentroid

public Point getCentroid()

Get the mathematical centroid point of a 2 dimensional representation of the Geometry (balancing point of a 2d cutout of the geometry). Only the x and y coordinate of the resulting point are calculated and populated. The resulting Point.getZ() and Point.getM() methods will always return null.

Returns:

centroid point

copy

public abstract Geometry copy()

Copy the geometry

Returns:

geometry copy

isEmpty

public abstract boolean isEmpty()

Is the Geometry empty

Returns:

true if empty

isSimple

public abstract boolean isSimple()

Determine if this Geometry has no anomalous geometric points, such as self intersection or self tangency

Returns:

true if simple

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
