Additional Inherited Members

- Public Member Functions inherited from llvm::opt::OptTable
virtual ~OptTable ()
unsigned getNumOptions () const
 Return the total number of option classes.
const Option getOption (OptSpecifier Opt) const
 Get the given Opt's Option instance, lazily creating it if necessary.
StringRef getOptionName (OptSpecifier id) const
 Lookup the name of the given option.
unsigned getOptionKind (OptSpecifier id) const
 Get the kind of the given option.
unsigned getOptionGroupID (OptSpecifier id) const

void setInitialOptionsFromEnvironment (const char *E)
 Specify the environment variable where initial options should be read.
void setGroupedShortOptions (bool Value)
 Support grouped short options. e.g. -ab represents -a -b.

◆ getPrefixesUnion()

ArrayRef< StringLiteral > llvm::opt::GenericOptTable::getPrefixesUnion ( ) const

The union of all option prefixes.

If an argument does not begin with one of these, it is an input.
