NamedStyle

All Known Implementing Classes:

NamedStyleImpl

public interface Style
extends Style

Indicates how geographical content should be displayed (we call this a style for simplicity; in the spec it is called a UserStyle (user-defined style)).

The details of this object are taken from the OGC Styled-Layer Descriptor Report (OGC 02-070) version 1.0.0.:

 <xsd:element name="UserStyle">
   <xsd:annotation>
     <xsd:documentation>
       A UserStyle allows user-defined styling and is semantically
       equivalent to a WMS named style.

Method Detail

setName

void setName(String name)

getDescription

Description getDescription()

Description for this style.

Specified by:

getDescription in interface Style

Returns:

Human readable description for use in user interfaces

Since:

2.5.x

setDefault

void setDefault(boolean isDefault)

Indicates that this is the default style.

Assume this is kept for GeoServer enabling a WMS to track which style is considered the default. May consider providing a clientProperties mechanism similar to Swing JComponent allowing applications to mark up the Style content for custom uses.

featureTypeStyles

List<FeatureTypeStyle> featureTypeStyles()

FeatureTypeStyles rendered in order of appearance in this list.

Specified by:

featureTypeStyles in interface Style

getDefaultSpecification

Symbolizer getDefaultSpecification()

This functionality is from an ISO specificaiton; and conflicts with the idea of an else rule presented by SLD.

Implementations may choose to look up the first symbolizer of an elseFilter or allow this to be provided?

Specified by:

getDefaultSpecification in interface Style

Returns:

Symbolizer to use if no rules work out.

setDefaultSpecification

void setDefaultSpecification(Symbolizer defaultSymbolizer)

Parameters:

defaultSymbolizer - To be used if a feature is not rendered by any of the rules
