This converts a name or symbol to the atomic number.

Detailed Description

The AtomInfo class provides information about atoms. The information is kept in a file named atominfo.kv in the SC library directory. That information can be overridden by the user.

Constructor & Destructor Documentation

  sc::AtomInfo::AtomInfo (const Ref< KeyVal > &)

The AtomInfo KeyVal constructor is used to generate a AtomInfo object from the input.

Default values will be read in from the atominfo.kv file in library directory. These can be overridden by specifying the keyword below. The library file is also read using a KeyVal constructor syntax, so consult that file for an example.

KeywordTypeDefaultDescription

Member Function Documentation

  double sc::AtomInfo::rgb (int Z, int color) const

These return information about the color of the atom for visualization programs.

  void sc::AtomInfo::save_data_state (StateOut &) [virtual]

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.

This must be implemented by the derived class if the class has data.

Reimplemented from sc::SavableState.
