virtual void Herwig::HeavyMesonWidthGenerator::dataBaseOutput ( ofstream &  output,
bool  header = true 
)
virtual

Output the initialisation info for the database.

Parameters
outputThe stream to output the information to
headeroutput the header.

Reimplemented from Herwig::GenericWidthGenerator.

◆ fullclone()

virtual IBPtr Herwig::HeavyMesonWidthGenerator::fullclone ( ) const
protectedvirtual

Returns
The partial width.

Reimplemented from Herwig::GenericWidthGenerator.
