public abstract class ALcdCylindrical
extends ALcdProjection
implements ILcdCylindrical, Cloneable

An ALcdCylindrical is an ILcdProjection that is obtained by wrapping a cylinder around the earth globe such that it touches the equator. Meridians are projected on the cylinder from the center of the globe and they are straight lines on the map. The central meridian is determined by its longitude and determines the position of the origin of the ALcdCylindrical, which is always on the equator.

public ALcdCylindrical()

Method Detail

setCentralMeridian

public void setCentralMeridian(double aLongitude)

Description copied from interface: ILcdCylindrical

Sets the centralMeridian to the meridian with longitude aLongitude.

Specified by:

setCentralMeridian in interface ILcdCylindrical

Parameters:

aLongitude - The new centralMeridian value.

See Also:

ILcdCylindrical.getCentralMeridian()

getCentralMeridian

public double getCentralMeridian()

Description copied from interface: ILcdCylindrical

Gets the longitude of the centralMeridian of this ILcdCylindrical.

Specified by:

getCentralMeridian in interface ILcdCylindrical

Returns:

the longitude of the centralMeridian of this ILcdCylindrical.

See Also:

ILcdCylindrical.setCentralMeridian(double)

getOrigin

public ILcdPoint getOrigin()

Description copied from interface: ILcdProjection

Origin of the projection is the ILcd2DEditablePoint that corresponds with origin (0, 0) of the cartesian coordinate system of the projection.

Specified by:

getOrigin in interface ILcdProjection

Returns:

the origin of the projection.

isContinuous

public boolean isContinuous()

Description copied from interface: ILcdProjection

An ILcdProjection is continuous if there are no interruptions in the world coordinates. Most projections are continuous.

Specified by:

isContinuous in interface ILcdProjection

Returns:

true if the projection is continuous, false otherwise.

loadProperties

public void loadProperties(String aPrefix,
                           Properties aProperty)
                    throws IllegalArgumentException

Load the property of an ALcdCylindrical: the central meridian of the projection. This method will, given aPrefix, analyze the aProperties object to set the property of this ALcdCylindrical. The value of following key is retrieved:

• <aPrefix><the name of the class that extends this abstract class>.centralMeridian

Specified by:

loadProperties in interface ILcdProjection

Parameters:

aPrefix - prefix of the property names.

aProperty - Properties object containing the serialized properties.

Throws:

IllegalArgumentException - if the projection cannot be created.

writePropertiesSFCT

public void writePropertiesSFCT(String aPrefix,
                                Properties aPropertySFCT)

Writes the property of an ALcdCylindrical: the central meridian of the projection. This method will, given aPrefix, store he property of this ALcdCylindrical into the aPropertiesSFCT object. The value of following key is stored:

• <aPrefix><the name of the class that extends this abstract class>.centralMeridian

Specified by:

writePropertiesSFCT in interface ILcdProjection

Parameters:

aPrefix - prefix for the property names.

aPropertySFCT - Properties object to store the serialized properties by side effect.

calculateCachedValues

protected void calculateCachedValues()

Constants based on the central meridian of the projection don't have to be recalculated every time a method is called. They only have to be calculated when the projection properties change. Within the methods the precalculated values then can be used in order to gain efficiency.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object aObject)

Description copied from interface: ILcdProjection

Checks if this ILcdProjection equals some other Object.

Specified by:

equals in interface ILcdProjection

Overrides:

equals in class Object

Parameters:

aObject - Object to compare with.

Returns:

true if the Object is an instance of the same ILcdProjection class and having the same projection properties, false otherwise.

clone

public Object clone()

Description copied from interface: ILcdProjection

Makes a deep clone of this ILcdProjection.

Specified by:

clone in interface ILcdProjection

Overrides:

clone in class ALcdProjection

Returns:

deep clone of this ILcdProjection.
