## Detailed Description

Normalizes the peak intensities spectrum-wise.

Either to a total intensity-sum of one (i.e. to total-ion-count; TIC) or to a maximum intensity of one.

Parameters of this class are:

Name | Type | Default | Restrictions | Description
--- | --- | --- | --- | ---
method | string | to_one | to_one, to_TIC | Normalize via dividing by TIC ('to_TIC') per spectrum or normalize to max. intensity of one ('to_one') per spectrum.

- Advanced parameter names are italic.

## ◆ updateMembers_()

void updateMembers_ | ( |  | ) |

This method is used to update extra member variables at the end of the setParameters() method.

Also call it at the end of the derived classes' copy constructor and assignment operator.

The default implementation is empty.

Reimplemented from DefaultParamHandler.
