class | ConfigPage |
A single declaration of a config variable, typically defined as one line in a .prc file, e.g.
"show-frame-rate-meter 1". This is really just a pairing of a string name (actually, a ConfigVariableCore pointer) to a string value.
Definition at line 36 of file configDeclaration.h.
string ConfigDeclaration::downcase | ( | const string & | s | ) | [static] |
Returns the input string with all uppercase letters converted to lowercase.
Definition at line 446 of file configDeclaration.cxx.
int ConfigDeclaration::extract_words | ( | const string & | str, |
vector_string & | words | ||
) | [static] |
Divides the string into a number of words according to whitespace.
The words vector should be cleared by the user before calling; otherwise, the list of words in the string will be appended to the end of whatever was there before.
The return value is the number of words extracted.
