Constructor Detail

Polyline

public Polyline()

Creates an empty polyline.

Polyline

public Polyline(VertexDescription vd)

Polyline

public Polyline(Point start,
                Point end)

Creates a polyline with one line segment.

Method Detail

createInstance

public Geometry createInstance()

Description copied from class: Geometry

Creates an instance of an empty geometry of the same type.

Specified by:

createInstance in class Geometry

Returns:

The new instance.

getDimension

public int getDimension()

Description copied from class: Geometry

Returns the topological dimension of the geometry object based on the geometry's type.

Returns 0 for point and multipoint.

Returns 1 for lines and polylines.

Returns 2 for polygons and envelopes

Returns 3 for objects with volume

Specified by:

getDimension in class Geometry

Returns:

Returns the integer value of the dimension of geometry.

getType

public Geometry.Type getType()

Description copied from class: Geometry

Returns the geometry type.

Specified by:

getType in class Geometry

Returns:

Returns the geometry type.

estimateMemorySize

public long estimateMemorySize()

Description copied from class: Geometry

Returns an estimate of this object size in bytes.

This estimate doesn't include the size of the VertexDescription object because instances of VertexDescription are shared among geometry objects.

Specified by:

estimateMemorySize in class Geometry

Returns:

Returns an estimate of this object size in bytes.

equals

public boolean equals(Object other)

Returns TRUE when this geometry has exactly same type, properties, and coordinates as the other geometry.

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns the hash code for the polyline.

Overrides:

hashCode in class MultiPath

addSegment

public void addSegment(Segment segment,
                       boolean bStartNewPath)

Description copied from class: MultiPath

Adds a new segment to this multipath.

Overrides:

addSegment in class MultiPath

Parameters:

segment - The segment to be added to this mulitpath.

bStartNewPath - TRUE if a new path will be added.

interpolateAttributes
