Class ExtendedCoordinateSequence

java.lang.Object

com.vividsolutions.jtsexample.geom.ExtendedCoordinateSequence

All Implemented Interfaces:

CoordinateSequence, Cloneable

public class ExtendedCoordinateSequence
extends Object
implements CoordinateSequence

Demonstrates how to implement a CoordinateSequence for a new kind of coordinate (an ExtendedCoordinate in this example). In this implementation, Coordinates returned by #toArray and #get are live -- parties that change them are actually changing the ExtendedCoordinateSequence's underlying data.

Version:

1.7

Constructor Detail

ExtendedCoordinateSequence

public ExtendedCoordinateSequence(ExtendedCoordinate[] coordinates)

Copy constructor -- simply aliases the input array, for better performance.

ExtendedCoordinateSequence

public ExtendedCoordinateSequence(Coordinate[] copyCoords)

Constructor that makes a copy of an array of Coordinates. Always makes a copy of the input array, since the actual class of the Coordinates in the input array may be different from ExtendedCoordinate.

ExtendedCoordinateSequence

public ExtendedCoordinateSequence(CoordinateSequence coordSeq)

Constructor that makes a copy of a CoordinateSequence.

ExtendedCoordinateSequence

public ExtendedCoordinateSequence(int size)

Constructs a sequence of a given size, populated with new ExtendedCoordinates.

Parameters:

size - the size of the sequence to create
