All Implemented Interfaces:

Drawing, Fill, Marshallable

public class Fill_Impl

extends Drawing_Impl

implements Fill, Marshallable

A Fill allows area geometries to be filled. There are two types of fills: solid-color and repeated GraphicFill. In general, if a Fill element is omitted in its containing element, no fill will be rendered. The default is a solid 50%-gray (color "#808080") opaque fill.

Method Detail

getFill

public java.awt.Color getFill(Feature feature)
                       throws FilterEvaluationException

Returns the (evaluated) value of the fill's CssParameter 'fill'.

Specified by:

getFill in interface Fill

Parameters:

feature - specifies the Feature to be used for evaluation of the underlying 'sld:ParameterValueType'

Returns:

the (evaluated) value of the parameter

Throws:

FilterEvaluationException - if the evaluation fails or the value is invalid

setFill

public void setFill(java.awt.Color color)

sets the value of the fill's CssParameter 'fill' as a simple color

Specified by:

setFill in interface Fill

Parameters:

color - color to be set

getOpacity

public double getOpacity(Feature feature)
                  throws FilterEvaluationException

Returns the (evaluated) value of the fill's CssParameter 'fill-opacity'.

Specified by:

getOpacity in interface Fill

Parameters:

feature - specifies the Feature to be used for evaluation of the underlying 'sld:ParameterValueType'

Returns:

the (evaluated) value of the parameter

Throws:

FilterEvaluationException - if the evaluation fails or the value is invalid

setOpacity

public void setOpacity(double opacity)

sets the value of the opacity's CssParameter 'opacity' as a value. Valid values ranges from 0 .. 1. If a value < 0 is passed it will be set to 0. If a value > 1 is passed it will be set to 1.

Specified by:

setOpacity in interface Fill

Parameters:

opacity - opacity to be set

exportAsXML

public java.lang.String exportAsXML()

exports the content of the CssParameter as XML formated String

Specified by:

exportAsXML in interface Marshallable

Returns:

xml representation of the CssParameter
