Member Typedef Documentation

typedef void(* EventCallback) (const EventDetails &event_details)

Debug event callback function.

Parameters
event_detailsobject providing information about the debug event

A EventCallback does not take possession of the event data, and must not rely on the data persisting after the handler returns.

Definition at line 138 of file v8-debug.h.

typedef void(* MessageHandler) (const Message &message)

This is now a no-op.

Run a JavaScript function in the debugger.

Parameters
funthe function to call
datapassed as second argument to the function With this call the debugger is entered and the function specified is called with the execution state as the first argument. This makes it possible to get access to information otherwise not available during normal JavaScript execution e.g. details on stack frames. Receiver of the function call will be the debugger context global object, however this is a subject to change. The following example shows a JavaScript function which when passed to v8::Debug::Call will return the current line of JavaScript execution.
function frame_source_line(exec_state) {
return exec_state.frame(0).sourceLine();
}
V8_DEPRECATED ( "No longer supported"  ,

V8_DEPRECATED ( "Use v8-inspector"  ,
static Local< Context >   GetDebugContextIsolate *isolate 
)

Debugger is running in its own context which is entered while debugger messages are being dispatched. This is an explicit getter for this debugger context. Note that the content of the debugger context is subject to change. The Context exists only when the debugger is active, i.e. at least one DebugEventListener or MessageHandler is set.

V8_DEPRECATED ( "No longer supported"  ,
static MaybeLocal< Context >   GetDebuggedContextIsolate *isolate 
)

While in the debug context, this method returns the top-most non-debug context, if it exists.

V8_DEPRECATED ( "No longer supported"  ,
static void   SetLiveEditEnabledIsolate *isolate, bool enable 
)

Enable/disable LiveEdit functionality for the given Isolate (default Isolate if not provided). V8 will abort if LiveEdit is unexpectedly used. LiveEdit is enabled by default.

V8_DEPRECATED ( "No longer supported"  ,
static MaybeLocal< Array >   GetInternalPropertiesIsolate *isolate, Local< Value > value 
)

Returns array of internal properties specific to the value type. Result has the following format: [<name>,

,...,<name>,

]. Result array will be allocated in the current context.

V8_DEPRECATED ( "No longer supported"  ,
static bool   IsTailCallEliminationEnabledIsolate *isolate 
)

Defines if the ES2015 tail call elimination feature is enabled or not. The change of this flag triggers deoptimization of all functions that contain calls at tail position.

V8_DEPRECATED ( "No longer supported"  ,
static void   SetTailCallEliminationEnabledIsolate *isolate, bool enabled 
)
