Field Detail

_anchor

protected CoordinateCartesianAbsolute _anchor

the relative origin of the element within its boundary extent to align to the world coordinate on the map

_areDetailsVisible

private boolean _areDetailsVisible

whether low-level details that would clutter the display should be rendered

_coordinate

protected final CoordinateWorld3D _coordinate

the world coordinate to align the anchor to

_id

protected final java.lang.String _id

Constructor Detail

A_ChartElement

public A_ChartElement(java.lang.String id,
                      CoordinateWorld3D coordinate)

Creates an abstract chart element.

Parameters:

id - - the unique element identifier

coordinate - - the coordinate of the origin

Method Detail

areDetailsVisible

public boolean areDetailsVisible()

Returns whether low-level details that would clutter the display should be rendered.

Returns:

the state

getColor

public abstract java.awt.Color getColor()

Gets the color of the glyph.

Returns:

the color

getCoordinate

public CoordinateWorld3D getCoordinate()

Gets the coordinate of the origin.

Returns:

the coordinate

getDesignator

public java.lang.String getDesignator()

Gets the station designator. This approach is a little non-OOPy, but for simplicity and clarify in the CMPS 450, it is fine.

This is valid only on tuneable chart elements.

Returns:

the designator

getFrequency

public A_Frequency<?> getFrequency()

Returns the frequency of this element, if it has one; otherwise, it fails with an assertion. This approach is a little non-OOPy, but for simplicity and clarify in the CMPS 450, it is fine.

This is valid only on tuneable chart elements.

Returns:

the frequency

getID

public java.lang.String getID()

Gets the unique element identifier.

Returns:

the identifier

hasFrequency

public boolean hasFrequency()

Returns whether this element has a frequency. This approach is a little non-OOPy, but for simplicity and clarify in the CMPS 450, it is fine.

Returns:

always returns false

render

public void render(java.awt.Graphics2D graphics,
                   I_WorldMappable mapper,
                   boolean areDetailsVisible)

Renders the glyph.

Parameters:

graphics - - the graphics context

mapper - - the mapper that translates screen and world coordinates

areDetailsVisible - - whether low-level details that would clutter the display should be rendered

renderLabel

protected void renderLabel(java.awt.Graphics2D graphics,
                           java.lang.String label)

Renders the label.

Parameters:

graphics - - the graphics context

label - - the label contents

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
