public LineSymbol(org.codehaus.jackson.JsonNode node)
           throws Exception

Instantiates an object of LineSymbol from a JsonNode.

Parameters:

node - the LineSymbol node.

Throws:

Exception

LineSymbol

public LineSymbol()

Instantiates an empty object of LineSymbol.

Method Detail

getColor

public Color getColor()

Returns the color of the line. The color is a 32bit value containing alpha as well as RGB. This 32bit value is not pre-multiplied, meaning that its alpha can be any value, regardless of the values of RGB. See the Color class for more details.

Returns:

the color in RGB color value.

setColor

public void setColor(Color color)

Sets the color of the line. The color is a 32bit value containing alpha as well as RGB. This 32bit value is not pre-multiplied, meaning that its alpha can be any value, regardless of the values of RGB. See the Color class for more details.

Parameters:

color - the color in ARGB color value.

getWidth

public float getWidth()

Returns the line width in pixels.

Returns:

Returns the line width in pixels.

setWidth

public void setWidth(float width)

Sets the line width in pixels.

Parameters:

width - the line width in pixels.

getAlpha

public int getAlpha()

Helper to getColor() that just returns the color's alpha value. This is the same as calling getColor() >>> 24. It always returns a value between 0 (completely transparent) and 255 (completely opaque).

Returns:

the alpha component of the symbol's color.

setAlpha

public void setAlpha(int alpha)

Sets the symbol transparency.

Parameters:

alpha - the alpha component of the symbol's color.
