Class CssParameter

java.lang.Object
  org.deegree.graphics.sld.CssParameter

All Implemented Interfaces:

Marshallable

public class CssParameter
extends Object
implements Marshallable

The simple SVG/CSS2 styling parameters are given with the CssParameter element, which is defined as follows:

   <xs:element name="CssParameter" type="sld:ParameterValueType"/>
      <xs:complexType name="ParameterValueType" mixed="true">
         <xs:choice minOccurs="0" maxOccurs="unbounded">
              <xs:element ref="wfs:expression"/>
          </xs:choice>
   </xs:complexType>

 

The parameter values are allowed to be complex expressions for maximum flexibility. The mixed="true" definition means that regular text may be mixed in with various sub-expressions, implying a text-substitution model for parameter values. Numeric and character-string data types are not distinguished, which may cause some complications.

Here are some usage examples:

  1. <CssParameter name="stroke-width">3</CssParameter>
  2. <CssParameter name="stroke-width">
          <wfs:Literal>3</wfs:Literal>
     </CssParameter>
  3. <CssParameter name="stroke-width">
          <wfs:Add>
              <wfs:PropertyName>/A</wfs:PropertyName>
              <wfs:Literal>2</wfs:Literal>
          </wfs:Add>
     </CssParameter>
  4. <Label>This is city "<wfs:PropertyName>/NAME</wfs:PropertyName>"
  of state <wfs:PropertyName>/STATE</wfs:PropertyName></Label>

 

The allowed SVG/CSS styling parameters for a stroke are: stroke (color), stroke-opacity, stroke-width, stroke-linejoin, stroke-linecap, stroke-dasharray, and stroke-dashoffset. The chosen parameter is given by the name attribute of the CssParameter element.
