Reimplemented from TObject.

Definition at line 109 of file TSpline.cxx.

◆ Draw()

void TSpline::Draw ( Option_t option = "")
virtual

Draw this function with its current attributes.

Possible option values are:

  • "SAME" superimpose on top of existing picture
  • "L" connect all computed points with a straight line
  • "C" connect all computed points with a smooth curve.
  • "P" add a polymarker at each knot

Note that the default value is "L". Therefore to draw on top of an existing picture, specify option "LSAME"

◆ SaveAs()

virtual void TSpline::SaveAs ( const char *  filename,
Option_t option 
) const
inlinevirtual

Save this object in the file specified by filename.

  • if "filename" contains ".root" the object is saved in filename as root binary file.
  • if "filename" contains ".xml" the object is saved in filename as a xml ascii file.
  • if "filename" contains ".cc" the object is saved in filename as C code independant from ROOT. The code is generated via SavePrimitive(). Specific code should be implemented in each object to handle this option. Like in TF1::SavePrimitive().
  • otherwise the object is written to filename as a CINT/C++ script. The C++ code to rebuild this object is generated via SavePrimitive(). The "option" parameter is passed to SavePrimitive. By default it is an empty string. It can be used to specify the Draw option in the code generated by SavePrimitive.

    The function is available via the object context menu.

Reimplemented from TObject.

Reimplemented in TSpline5, and TSpline3.
