Exceptions

The library allows to throw exceptions from C++ code. Such exceptions will be converted to v8::Exception::Error and can be catched in JavaScript code.

It is also possible to throw a V8 exception with v8pp::throw_ex(v8::Isolate* isolate, char const* str, exception_ctor) function declared in a v8pp/throw_ex.hpp header, where exception_ctor is a v8::Exception constructor:

• v8::Exception::Error (default)
• v8::Exception::RangeError
• v8::Exception::ReferenceError
• v8::Exception::SyntaxError
• v8::Exception::TypeError

v8::Isolate* isolate = v8::Isolate::GetCurrent();

v8::Local<v8::Value> ex = v8pp::throw_ex(isolate, "my error message");
