  • Constructor Details

    • LineSymbolizerImpl

      protected LineSymbolizerImpl()
      Creates a new instance of DefaultLineSymbolizer
    • LineSymbolizerImpl

      protected LineSymbolizerImpl(Stroke stroke, Expression offset, Unit<Length> uom, String geom, String name, Description desc)
  • Method Details

    • getPerpendicularOffset

      public Expression getPerpendicularOffset()
      Description copied from interface: LineSymbolizer
      PerpendicularOffset allows to draw lines in parallel to the original geometry. For complex line strings these parallel lines have to be constructed so that the distance between original geometry and drawn line stays equal. This construction can result in drawn lines that are actually smaller or longer than the original geometry.

      The distance is in uoms and is positive to the left-hand side of the line string. Negative numbers mean right. The default offset is 0.

      Specified by:
      getPerpendicularOffset in interface LineSymbolizer
      Returns:
      Expression
    • setPerpendicularOffset

      public void setPerpendicularOffset(Expression offset)
      Description copied from interface: LineSymbolizer
      Define an offset to draw lines in parallel to the original geometry.
      Specified by:
      setPerpendicularOffset in interface LineSymbolizer
      Parameters:
      offset - Distance in UOMs to offset line; left-hand side is positive; right-hand side is negative; the default value is 0
    • getStroke

      public StrokeImpl getStroke()
      Provides the graphical-symbolization parameter to use for the linear geometry.
      Specified by:
      getStroke in interface LineSymbolizer
      Returns:
      The Stroke style to use when rendering lines.
    • setStroke

      public void setStroke(Stroke stroke)
      Sets the graphical-symbolization parameter to use for the linear geometry.
      Specified by:
      setStroke in interface LineSymbolizer
      Parameters:
      stroke - The Stroke style to use when rendering lines.
    • accept

      public Object accept(TraversingStyleVisitor visitor, Object data)
      Accepts a StyleVisitor to perform some operation on this LineSymbolizer.
      Specified by:
      accept in interface LineSymbolizer
      Specified by:

      Parameters:
      visitor - The visitor to accept.
      Returns:
      value produced
    • accept

      public void accept(StyleVisitor visitor)
      Specified by:
      accept in interface Symbolizer
