Interface Style

All Known Subinterfaces:
NamedStyle
All Known Implementing Classes:
BasicLineStyle, BasicPolygonStyle, NamedStyleImpl, StyleImpl
public interface Style
A UserStyle is at the same semantic level as a NamedStyle used in the context of a WMS. In a sense, a named style can be thought of as a reference to a hidden UserStyle that is stored inside of a map server.

A portrayal catalog consits of a set of feature portrayal objects. Many may exist for each feature type that may occur in the dataset. each feature object has assigned a set of portrayal rules. This class is a merged between ISO 19117 Portrayal and OGC SLD 1.1.0

  • Method Details

    • getName

      String getName()
      Style name (machine readable, don't show to users)
      Returns:
      String, identification name of this style

    • setName

      void setName(String name)

    • setBackground

      void setBackground(Fill background)

    • getDescription

      Description getDescription()
      Description for this style.
      Returns:
      Human readable description for use in user interfaces
      Since:
      2.5.x

    • isDefault

      boolean isDefault()
      The IsDefault element identifies whether a style is the default style of a layer, for use in SLD ‘library mode’ when rendering or for storing inside of a map server. IsDefault uses “1” or “true” for true and “0” or “false” for false. The default value is “0”.

    • 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.

    • 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?

      Returns:
      Symbolizer to use if no rules work out.

    • accept

      Object accept(TraversingStyleVisitor visitor, Object extraData)
      calls the visit method of a StyleVisitor
      Parameters:
      visitor - the style visitor

    • setDefaultSpecification

      void setDefaultSpecification(Symbolizer defaultSymbolizer)
      Parameters:
      defaultSymbolizer - To be used if a feature is not rendered by any of the rules

    • accept

      void accept(StyleVisitor visitor)
      Used to navigate Style information during portrayal.

    • getBackground

      default Fill getBackground()
      The background Fill , if any, null otherwise
