関数

v8::Local< Value > v8::TryCatch::Exception ( ) const

Returns the exception caught by this try/catch block. If no exception has been caught an empty handle is returned.

The returned handle is valid until this TryCatch block has been destroyed.

api.cc の 1098 行で定義されています。

bool v8::TryCatch::HasCaught ( ) const

Returns true if an exception has been caught by this try/catch block.

api.cc の 1093 行で定義されています。

参照先 exception_, と v8::internal::Object.

参照元 v8::internal::DebugMessageThread::DebugEvent(), Exception(), Message(), と v8::internal::Execution::TryCall().

v8::Local< v8::Message > v8::TryCatch::Message ( ) const

Returns the message associated with this exception. If there is no message associated an empty handle is returned.

The returned handle is valid until this TryCatch block has been destroyed.

api.cc の 1109 行で定義されています。

参照先 v8::internal::Smi::FromInt(), HasCaught(), message_, v8::Utils::MessageToLocal(), と v8::internal::Object.

void v8::TryCatch::Reset ( )

Clears any exceptions that may have been caught by this try/catch block. After this method has been called, HasCaught() will return false.

It is not necessary to clear a try/catch block before using it again; if another exception is thrown the previously caught exception will just be overwritten. However, it is often a good idea since it makes it easier to determine which operation threw a given exception.

api.cc の 1119 行で定義されています。

void v8::TryCatch::SetCaptureMessage ( bool value )

Set whether or not this TryCatch should capture a Message object which holds source information about where the exception occurred. True by default.

api.cc の 1130 行で定義されています。

参照先 capture_message_.

void v8::TryCatch::SetVerbose ( bool value )

Set verbosity of the external exception handler.

By default, exceptions that are caught by an external exception handler are not reported. Call SetVerbose with true on an external exception handler to have exceptions caught by the handler reported as if they were not caught.
