Class TLcdSLDParameterValue

java.lang.Object
com.luciad.datamodel.TLcdDataObject
com.luciad.ogc.sld.model.TLcdSLDParameterValue
All Implemented Interfaces:
ILcdDataObject, ILcdGenericExpression, ILcdCloneable, ILcdDeepCloneable, Cloneable
public class TLcdSLDParameterValue extends TLcdDataObject implements ILcdGenericExpression
The "ParameterValue" uses OGC Filter expressions to give values for SLD graphic parameters. A "mixed" element-content model is used with textual substitution for values. E.g. the value for a color consists of 6 hexadecimal digits preceded by a #. This could be given by 
 <CssParameter name="fill">#00<ogc:PropertyName>greenband</ogc:PropertyName>FF</CssParameter>

If you want to retrieve the actual value for a given object, you can construct an ILcdEvaluator using the TLcdSLDFunctionEvaluatorFactory.

    • TLcdSLDParameterValue

      public TLcdSLDParameterValue(Vector aContents)
      Constructs a parameterized value.
      Parameters:
      aContents - the contents that should be evaluated. The contents can be mixed, i.e., a combination of text and expressions. The Vector should therefore only contain String or ILcdOGCExpression objects.

    • TLcdSLDParameterValue

      public TLcdSLDParameterValue(ILcdOGCExpression aOGCExpression)
      Constructor for the simple case where the contents only consists of an expression.
      Parameters:
      aOGCExpression - the given expression.

    • TLcdSLDParameterValue

      public TLcdSLDParameterValue(String aTextContent)
      Constructor for the simple case where the contents consists only of text.
      Parameters:
