LLVM: llvm::json Namespace Reference (original) (raw)

Classes
class	Array
	An Array is a JSON array, which contains heterogeneous JSON values. More...
class	Object
	An Object is a JSON object, which maps strings to heterogenous JSON values. More...
class	ObjectKey
	ObjectKey is a used to capture keys in Object. More...
class	ObjectMapper
	Helper for mapping JSON objects onto protocol structs. More...
class	OStream
	json::OStream allows writing well-formed JSON without materializing all structures as json::Value ahead of time. More...
class	ParseError
class	Path
	A "cursor" marking a position within a Value. More...
class	Value
	A Value is an JSON value of unknown type. More...

Functions

◆ abbreviate()

◆ encodeUtf8()

void llvm::json::encodeUtf8 ( uint32_t Rune, std::string & Out )	static

◆ fixUTF8()

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()

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