Member Function Documentation

◆ ErrorLevel()

int ErrorLevel ( ) const

Returns the error level of the message.

◆ Get()

Local<String> Get ( ) const

◆ GetEndColumn() [1/2]

int GetEndColumn ( ) const

Returns the index within the line of the last character where the error occurred.

◆ GetEndColumn() [2/2]

V8_WARN_UNUSED_RESULT Maybe<int> GetEndColumn ( Local< Context >  context) const

◆ GetEndPosition()

int GetEndPosition ( ) const

Returns the index within the script of the last character where the error occurred.

◆ GetIsolate()

Isolate* GetIsolate ( ) const

Return the isolate to which the Message belongs.

◆ GetLineNumber()

V8_WARN_UNUSED_RESULT Maybe<int> GetLineNumber ( Local< Context >  context) const

Returns the number, 1-based, of the line where the error occurred.

◆ GetScriptOrigin()

ScriptOrigin GetScriptOrigin ( ) const

Returns the origin for the script from where the function causing the error originates.

◆ GetScriptResourceName()

Local<Value> GetScriptResourceName ( ) const

Returns the resource name for the script from where the function causing the error originates.

◆ GetSource()

V8_WARN_UNUSED_RESULT MaybeLocal<String> GetSource ( Local< Context >  context) const

◆ GetSourceLine()

V8_WARN_UNUSED_RESULT MaybeLocal<String> GetSourceLine ( Local< Context >  context) const

◆ GetStackTrace()

Local<StackTrace> GetStackTrace ( ) const

Exception stack trace. By default stack traces are not captured for uncaught exceptions. SetCaptureStackTraceForUncaughtExceptions allows to change this option.

◆ GetStartColumn() [1/2]

int GetStartColumn ( ) const

Returns the index within the line of the first character where the error occurred.

◆ GetStartColumn() [2/2]

V8_WARN_UNUSED_RESULT Maybe<int> GetStartColumn ( Local< Context >  context) const

◆ GetStartPosition()

int GetStartPosition ( ) const

Returns the index within the script of the first character where the error occurred.

◆ GetWasmFunctionIndex()

int GetWasmFunctionIndex ( ) const

Returns the Wasm function index where the error occurred. Returns -1 if message is not from a Wasm script.

◆ IsOpaque()

bool IsOpaque ( ) const

◆ IsSharedCrossOrigin()

bool IsSharedCrossOrigin ( ) const

Passes on the value set by the embedder when it fed the script from which this Message was generated to V8.

◆ PrintCurrentStackTrace()

static void PrintCurrentStackTrace ( Isolate *  isolate,
std::ostream &  out 
)
static
