Error	parse (void Opts, ArrayRef< const char > Args, unsigned &Consumed, BumpPtrAllocator &Alloc) override
	Parses the option spelled by Args[0], which may take Args[1] as its value, into `Opts`, which is global() or a context's values, and sets `Consumed` to the number of arguments it spans.
void *	global () override
	Returns the values that ParseCommandLineOptions sets.

	Returns the default values.
void *	copyDefault (BumpPtrAllocator &Alloc) const override
	Returns a copy of getDefault() allocated from `Alloc`.
void	reset () override
	Restores the default values.
Public Member Functions inherited from llvm::cl::LibraryOptions
virtual void	forEachOption (function_ref< void(StringRef Spelling, StringRef MetaVar, StringRef Help)> Fn) const =0
	Calls `Fn` with the spelling of each option without its prefix (e.g.
bool	isPerContext () const
	Whether every reader of the options goes through a context's LibraryOptionsContext, so that they need not be set in global().

Member Function Documentation

◆ copyDefault()

void * llvm::opt::LibraryOptionsParser::copyDefault ( BumpPtrAllocator & Alloc ) const

inlineoverridevirtual

Returns a copy of getDefault() allocated from Alloc.

Implements llvm::cl::LibraryOptions.

Definition at line 144 of file LibraryOptions.h.

References llvm::Alloc.

◆ forEachOption()

void LibraryOptionsParser::forEachOption ( function_ref< void(StringRef, StringRef, StringRef)> Fn ) const

override

Definition at line 20 of file LibraryOptions.cpp.

References llvm::opt::Option::GroupClass, llvm::opt::Option::InputClass, llvm::opt::Option::SeparateOrEqClass, T, llvm::Table, and llvm::opt::Option::UnknownClass.

◆ getDefault()

const void * llvm::opt::LibraryOptionsParser::getDefault ( ) const

inlineoverridevirtual

Returns the default values.

Implements llvm::cl::LibraryOptions.

Definition at line 143 of file LibraryOptions.h.

◆ global()

void * llvm::opt::LibraryOptionsParser::global ( )

inlineoverridevirtual

Returns the values that ParseCommandLineOptions sets.

Implements llvm::cl::LibraryOptions.

Definition at line 142 of file LibraryOptions.h.

◆ parse()

Error LibraryOptionsParser::parse	(	void *	Opts,
		ArrayRef< const char * >	Args,
		unsigned &	Consumed,
		BumpPtrAllocator &	Alloc )

overridevirtual

Parses the option spelled by Args[0], which may take Args[1] as its value, into Opts, which is global() or a context's values, and sets Consumed to the number of arguments it spans.

The strings in Args and the memory from Alloc remain valid as long as Opts is used.
