Function Documentation

◆ CleanType()

string TClassEdit::CleanType ( const char *  typeDesc,
int  mode = 0,
const char **  tail = 0 
)

Cleanup type description, redundant blanks removed and redundant tail ignored return *tail = pointer to last used character if (mode==0) keep keywords if (mode==1) remove keywords outside the template params if (mode>=2) remove the keywords everywhere.

if (tail!=0) cut before the trailing *

The keywords currently are: "const" , "volatile" removed
