Member Function Documentation

void flag ( string  keyIn,
bool  nowIn,
bool  force = false 
)

Change current value, respecting limits.

Change current value. Respect limits unless force==true. If key not recognised, add new key if force==true, otherwise ignore.

Print:quiet triggers a whole set of changes.

void forceMode ( string  keyIn,
int  nowIn 
)
inline

Methods kept for backwards compatability with 8.223 and earlier. (To be removed in next major release.)

Loop over the flag map (using iterator), and process names.

Done without having found a non-SoftQCD/LowEnergyQCD process on.

bool init ( string  startFile = "../share/Pythia8/xmldoc/Index.xml",

)

Read in database from specific file.

Settings class. This class contains flags, modes, parms and words used in generation.

Don't initialize if it has already been done and not in append mode.

Reset readString history.

List of files to be checked. Start with input file.

If nontrivial startfile path, then use that for other files as well.

Loop over files. Open them for read.

Check that instream is OK.

Read in one line at a time.

Get first word of a line, to interpret it as tag. Remove "more".

Skip ahead if not interesting. Only look for new files in startfile.

Read and append continuation line(s) if line does not contain >.

Remove extra blanks before an = sign.

Add file also to be read.

Find name attribute.

Check that default value attribute present, and whether max and min.

Check for occurence of a bool and add to flag map.

Check for occurence of an int and add to mode map.

Enforce check that only allowed options are accepted.

void listAll ( )
inline

Print out table of database, either all or only changed ones, or ones containing a given string.

bool mode ( string  keyIn,
int  nowIn,
bool  force = false 
)

For modepick and modefix fail if values are outside range.

Tune:ee and Tune:pp each trigger a whole set of changes.

string output ( string  keyIn,
bool  fullLine = true 
)

Give back current value(s) as a string, whatever the type.

Default string echoes input key =.

Identify flag, mode, parm or word, and convert to string.

Default value, possible endline and done.

bool readString ( string  line,
bool  warn = true 
)

Read in one update from a single line.

Read in updates from a character string, like a line of a file. Is used by readString (and readFile) in Pythia.

If empty line then done.

If unfinished line then add new to existing, else use input line as is.

If first character is not a letter, then taken to be a comment line.

Replace an equal sign by a blank to make parsing simpler, except after {.

Get first word of a line.

Replace two colons by one (:: -> :) to allow for such mistakes.

Check whether this is in the database.

For backwards compatibility: old (parts of) names mapped onto new ones. This code currently has no use, but is partly preserved for the day it may be needed again.

Warn and done if not in database.

Find value. Warn if none found.

If value is a ? then echo the current value.

Check for FORCE= statements (to ignore min/max values)

Read value from next word

If string begins with { then find matching } and extract contents.

If not } on same line then must append next line and try again.

Update flag map; allow many ways to say yes.

Update mode map.

Update parm map.

Update word map.

Update fvec map.

Update mvec map.

Update pvec map.

Update wvec map.

Store history of valid readString statements

Done.

Then let normal init do the rest.

void resetMode ( string  keyIn)

For Tune:ee and Tune:pp must also restore variables involved in tunes.

bool writeFile ( string  toFile,

Write updates or everything to user-defined file.

Open file for writing.

Hand over real work to next method.

)

Write updates or everything to user-defined stream (or file).

Write simple header as comment.
