  • Constructor Details

    • PolygonSymbolizerImpl

      protected PolygonSymbolizerImpl()
      Creates a new instance of DefaultPolygonStyler

    • PolygonSymbolizerImpl

      protected PolygonSymbolizerImpl(Stroke stroke, Fill fill, Displacement disp, Expression offset, Unit<Length> uom, String geom, String name, Description desc)

  • Method Details

    • getPerpendicularOffset

      public Expression getPerpendicularOffset()
      Description copied from interface: PolygonSymbolizer
      PerpendicularOffset works as defined for LineSymbolizer, allowing to draw polygons smaller or larger than their actual geometry. The distance is in uoms and is positive to the outside of the polygon. Negative numbers mean drawing the polygon smaller. The default offset is 0.
      Specified by:
      getPerpendicularOffset in interface PolygonSymbolizer
      Returns:
      Expression

    • setPerpendicularOffset

      public void setPerpendicularOffset(Expression offset)
      Description copied from interface: PolygonSymbolizer
      PerpendicularOffset works as defined for LineSymbolizer, allowing to draw polygons smaller or larger than their actual geometry.
      Specified by:
      setPerpendicularOffset in interface PolygonSymbolizer
      Parameters:
      offset - Offset from the edge polygon positive outside; negative to the inside with a default of 0.

    • getDisplacement

      public Displacement getDisplacement()
      Description copied from interface: PolygonSymbolizer
      The Displacement gives the X and Y displacements from the original geometry. This element may be used to avoid over-plotting of multiple PolygonSymbolizers for one geometry or supplying "shadows" of polygon gemeotries. The displacements are in units of pixels above and to the right of the point. The default displacement is X=0, Y=0.
      Specified by:
      getDisplacement in interface PolygonSymbolizer
      Returns:
      Displacement

    • setDisplacement

      public void setDisplacement(Displacement displacement)
      Description copied from interface: PolygonSymbolizer
      Provide x / y offset in pixels used to crate shadows.
      Specified by:
      setDisplacement in interface PolygonSymbolizer

    • getFill

      public Fill getFill()
      Provides the graphical-symbolization parameter to use to fill the area of the geometry.
      Specified by:
      getFill in interface PolygonSymbolizer
      Returns:
      The Fill style to use when rendering the area.

    • setFill

      public void setFill(Fill fill)
      Sets the graphical-symbolization parameter to use to fill the area of the geometry.
      Specified by:
      setFill in interface PolygonSymbolizer
      Parameters:
      fill - The Fill style to use when rendering the area.

    • getStroke

      public StrokeImpl getStroke()
      Provides the graphical-symbolization parameter to use for the outline of the Polygon.
      Specified by:
      getStroke in interface PolygonSymbolizer
      Returns:
      The Stroke style to use when rendering lines.

    • setStroke

      public void setStroke(Stroke stroke)
      Sets the graphical-symbolization parameter to use for the outline of the Polygon.
      Specified by:
      setStroke in interface PolygonSymbolizer
      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 PolygonSymbolizer
      Specified by:
      accept in interface Symbolizer
      Parameters:
      visitor - The visitor to accept.
      Returns:
      value produced

    • accept

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

    • clone

      public Object clone()
      Creates a deep copy clone. TODO: Need to complete the deep copy, currently only shallow copy.
      Specified by:
      clone in interface Cloneable
      Overrides:
      clone in class Object
      Returns:
      The deep copy clone.
