◆ code_event_handler

JitCodeEventHandler v8::Isolate::CreateParams::code_event_handler

Allows the host application to provide the address of a function that is notified each time code is added, moved or removed.

◆ constraints

ResourceConstraints v8::Isolate::CreateParams::constraints

ResourceConstraints to use for the new Isolate.

Definition at line 4385 of file v8.h.

◆ enable_serializer

bool v8::Isolate::CreateParams::enable_serializer

This flag currently renders the Isolate unusable.

Definition at line 4390 of file v8.h.

Referenced by main(), and v8::Isolate::New().

◆ entry_hook

FunctionEntryHook v8::Isolate::CreateParams::entry_hook

The optional entry_hook allows the host application to provide the address of a function that's invoked on entry to every V8-generated function.

Note that entry_hook is invoked at the very start of each generated function. Furthermore, if an entry_hook is given, V8 will always run without a context snapshot.
