class OStream

Declaration

class OStream { /* full declaration omitted */ };

Description

for (const Event &E : Events) { J.objectBegin(); J.attribute("timestamp", int64_t(E.Time)); J.attributeBegin("participants"); for (const Participant &P : E.Participants) J.value(P.toString()); J.attributeEnd(); J.objectEnd(); } J.arrayEnd(); If the call sequence isn't valid JSON, asserts will fire in debug mode. This can be mismatched begin()/end() pairs, trying to emit attributes inside an array, and so on. With asserts disabled, this is undefined behavior.

Methods

¶OStream(llvm::raw_ostream& OS,
        unsigned int IndentSize = 0)

Declared at: llvm/include/llvm/Support/JSON.h:760

Parameters

llvm::raw_ostream& OS

unsigned int IndentSize = 0

¶void array(llvm::json::OStream::Block Contents)

Description

Emit an array whose elements are emitted in the provided Block.

Declared at: llvm/include/llvm/Support/JSON.h:780

Parameters

llvm::json::OStream::Block Contents

¶void arrayBegin()

Declared at: llvm/include/llvm/Support/JSON.h:811

¶void arrayEnd()

Declared at: llvm/include/llvm/Support/JSON.h:812

¶void attribute(llvm::StringRef Key,
               const llvm::json::Value& Contents)

Description

Emit an attribute whose value is self-contained (number, vector <int > etc).

Declared at: llvm/include/llvm/Support/JSON.h:796

Parameters

llvm::StringRef Key

const llvm::json::Value& Contents

¶void attributeArray(
    llvm::StringRef Key,
    llvm::json::OStream::Block Contents)

Description

Emit an attribute whose value is an array with elements from the Block.

Declared at: llvm/include/llvm/Support/JSON.h:800

Parameters

llvm::StringRef Key

llvm::json::OStream::Block Contents

¶void attributeBegin(llvm::StringRef Key)

Declared at: llvm/include/llvm/Support/JSON.h:815

Parameters

llvm::StringRef Key

¶void attributeEnd()

Declared at: llvm/include/llvm/Support/JSON.h:816

¶void attributeObject(
    llvm::StringRef Key,
    llvm::json::OStream::Block Contents)

Description

Emit an attribute whose value is an object with attributes from the Block.

Declared at: llvm/include/llvm/Support/JSON.h:804

Parameters

llvm::StringRef Key

llvm::json::OStream::Block Contents

¶void flush()

Description

Flushes the underlying ostream. OStream does not buffer internally.

Declared at: llvm/include/llvm/Support/JSON.h:771

¶void object(llvm::json::OStream::Block Contents)

Description

Emit an object whose elements are emitted in the provided Block.

Declared at: llvm/include/llvm/Support/JSON.h:786

Parameters

llvm::json::OStream::Block Contents

¶void objectBegin()

Declared at: llvm/include/llvm/Support/JSON.h:813

¶void objectEnd()

Declared at: llvm/include/llvm/Support/JSON.h:814

¶void value(const llvm::json::Value& V)

Description

Emit a self-contained value (number, string, vector <string > etc).

Declared at: llvm/include/llvm/Support/JSON.h:778

Parameters

const llvm::json::Value& V

¶~OStream()
