Function Documentation

fixUTF8()

std::string llvm::json::fixUTF8

(

llvm::StringRef

S

)

Replaces invalid UTF-8 sequences in S with the replacement character (U+FFFD).

The returned string is valid UTF-8. This is much slower than isUTF8, so test that first.

isUTF8()

bool llvm::json::isUTF8	(	llvm::StringRef	S,
		size_t *	ErrOffset = nullptr
	)

Returns true if S is valid UTF-8, which is required for use as JSON.

If it returns false, Offset is set to a byte offset near the first error.

parse()

Expected< Value > llvm::json::parse

(

llvm::StringRef

JSON

)

Parses the provided JSON source, or returns a ParseError.

The returned Value is self-contained and owns its strings (they do not refer to the original source).
