      Constructor.

  - ### Method Detail

    - #### read

          public PgJvxSrc[] read(java.io.BufferedReader in)

      Read a DXF geometry file and return an array of new geometries.

      The returned array of geometry may contain keyframes of an animation. This is checked with the method `isAnimation()`.

      Alternatively, one may call load(BuffereredReader) followed by getGeometries() resp. getAnimations() to have a finer control about which information one wants to use from a source. For example, optional display information must be retrieve by a subsequent call getDisplayOption() if available.

      Specified by:
        `read` in interface `PgLoaderIf`
      Overrides:
        `read` in class `PgAbstractLoader`
      Parameters:
        `in` - BufferedReader to read textual data from.
      Returns:
        Array of JVX geometries.

        `write(Writer, PgJvxSrc [])`

      Version:
        10.06.01, 1.10 revised (kp) Return an array instead a single geometry.
        06.08.00, 1.00 created (kp)

    - #### write

          public boolean write(java.io.Writer writer,
                               PgJvxSrc[] geomArr)
                        throws java.io.IOException

      Write an array of geometries into an output stream writer.
      Specified by:
        `write` in interface `PgLoaderIf`
      Overrides:
        `write` in class `PgAbstractLoader`
      Parameters:
        `writer` - Write all data to this stream
        `geomArr` - Array with geometries to save
      Returns:
        `true` on success.
      Throws:
        `java.io.IOException`
      See Also:
        `read(BufferedReader)`
      Version:
        19.06.07, 2.00 revised (ur) Implemented writing of data.
        10.06.01, 1.10 revised (kp) Save array of geometries instead of single geometry.
        06.08.00, 1.00 created (kp)
