Class AbstractDirectPosition

Object

AbstractDirectPosition

All Implemented Interfaces:

Position, DirectPosition

Direct Known Subclasses:

DirectPosition1D, GeneralDirectPosition

public abstract class AbstractDirectPosition
extends Object
implements DirectPosition

Base class for direct position implementations. This base class provides default implementations for toString(), equals(java.lang.Object) and hashCode() methods.

This class do not holds any state. The decision to implement Serializable or org.geotools.util.Cloneable interfaces is left to implementors.

Constructor Detail

AbstractDirectPosition

protected AbstractDirectPosition()

Constructs a direct position.

Method Detail

getDirectPosition

public DirectPosition getDirectPosition()

Returns always this, the direct position for this position.

Specified by:

getDirectPosition in interface Position

Returns:

The direct position (may be this).

Since:

2.5

setPosition

public void setPosition(DirectPosition position)

Sets this direct position to the given position. If the given position is null, then all ordinate values are set to NaN.

Parameters:

position - The new position.

Since:

2.5

getCoordinate

public double[] getCoordinate()

Returns a sequence of numbers that hold the coordinate of this position in its reference system.

Specified by:

getCoordinate in interface DirectPosition

Returns:

The coordinates.

toString

public String toString()

Returns a string representation of this coordinate. The default implementation is okay for occasional formatting (for example for debugging purpose). But if there is a lot of positions to format, users will get more control by using their own instance of CoordinateFormat.

Overrides:

toString in class Object

hashCode

public int hashCode()

Returns a hash value for this coordinate.

Specified by:

hashCode in interface DirectPosition

Overrides:

hashCode in class Object

Returns:

A hash code value for this position.

equals

public boolean equals(Object object)

Returns true if the specified object is also a direct position with equals coordinate and CRS.

Specified by:

equals in interface DirectPosition

Overrides:

equals in class Object

Parameters:

object - The object to compare with this position.

Returns:

true if the given object is equals to this position.
