Class ALcdSVGShapeWriter

java.lang.Object
com.luciad.format.svg.ALcdSVGShapeWriter
All Implemented Interfaces:
ILcdSVGShapeWriter
Direct Known Subclasses:
TLcdSVGUnStyledShapeWriter
public abstract class ALcdSVGShapeWriter extends Object implements ILcdSVGShapeWriter
This is the abstract superclass for TLcdSVGUnStyledShapeWriter. It contains an implementation of the writeElement method and some utility methods to write properties of elements. Protected method are added for supported elements:
  • ILcdCircle
  • ILcdPolyline
  • ILcdPolygon
  • ILcdText
  • ILcdBounds
  • ILcdShapeList
  • ILcdEllipse
When the property TrueSVG is false ( default value), additional non-svg shapes can be written
  • ILcdPoint
  • ILcdArcBand

  • Constructor Details

    • ALcdSVGShapeWriter

      public ALcdSVGShapeWriter()

  • Method Details

    • setTrueSVG

      public void setTrueSVG(boolean aTrueSVG)
      Set to write true SVG or not.
      Specified by:
      setTrueSVG in interface ILcdSVGShapeWriter
      Parameters:
      aTrueSVG - if true, true SVG will be written, if false additional shapes can be written.

    • isTrueSVG

      public boolean isTrueSVG()
      Checks if this writer is a True SVG writer or not.
      Returns:
      true if the writer is a true SVG writer.

    • writeElement

      public void writeElement(Object aObject, Writer aTarget) throws IOException
      Writes an object on the writer as an SVG element. This implementation checks the class of the object and writes the following shapes:
      • ILcdCircle
      • ILcdPolyline
      • ILcdPolygon
      • ILcdText
      • ILcdEllipse
      • ILcdShapeList
      • ILcdBounds
      unconditionally as elements. If trueSVG is set to true, these shapes are also written to the writer:
      • ILcdPoint
      • ILcdArcband
      All these shapes are written using the according write method. If the object is none of the above, nothing is passed to the writer.
      Specified by:
      writeElement in interface ILcdSVGShapeWriter
      Parameters:
      aObject - the Object to be written.
      aTarget - the StringBuffer to write the given element to/
      Throws:
      IOException - when output to aTarget fails.
