    • getShapeType

      public ShapeType getShapeType()
      Description copied from interface: ShapeHandler
      Get the ShapeType of this handler.
      Specified by:
      getShapeType in interface ShapeHandler
      Returns:
      The ShapeType.
    • getLength

      public int getLength(Object geometry)
      Description copied from interface: ShapeHandler
      Get the length of the given geometry Object in bytes not 16-bit words. This is easier to keep track of, since the ByteBuffer deals with bytes. Do not include the 8 bytes of record.
      Specified by:
      getLength in interface ShapeHandler
      Parameters:
      geometry - The geometry to analyze.
      Returns:
      The number of bytes the shape will take up.
    • read

      public Object read(ByteBuffer buffer, ShapeType type, boolean flatFeature)
      Description copied from interface: ShapeHandler
      Read a geometry from the ByteBuffer. The buffer's position, byteOrder, and limit are set to that which is needed. The record has been read as well as the shape type integer. The handler need not worry about reading unused information as the ShapefileReader will correctly adjust the buffer position after this call.
      Specified by:
      read in interface ShapeHandler
      Parameters:
      buffer - The ByteBuffer to read from.
      Returns:
      A geometry object.
    • write

      public void write(ByteBuffer buffer, Object geometry)
      Description copied from interface: ShapeHandler
      Write the geometry into the ByteBuffer. The position, byteOrder, and limit are all set. The handler is not responsible for writing the record or shape type integer.
      Specified by:
      write in interface ShapeHandler
      Parameters:
      buffer - The ByteBuffer to write to.
      geometry - The geometry to write.
