Detailed Description

Representation of a JavaScript stack trace. The information collected is a snapshot of the execution stack and the information remains valid after execution continues.

Member Enumeration Documentation

◆ StackTraceOptions

enum StackTraceOptions

Flags that determine what information is placed captured for each StackFrame when grabbing the current stack trace. Note: these options are deprecated and we always collect all available information (kDetailed).

Member Function Documentation

◆ CurrentScriptNameOrSourceURL()

static Local<String> CurrentScriptNameOrSourceURL ( Isolate * isolate )

static

Returns the first valid script name or source URL starting at the top of the JS stack. The returned string is either an empty handle if no script name/url was found or a non-zero-length string.

This method is equivalent to calling StackTrace::CurrentStackTrace and walking the resulting frames from the beginning until a non-empty script name/url is found. The difference is that this method won't allocate a stack trace.

◆ CurrentStackTrace()

static Local<StackTrace> CurrentStackTrace	(	Isolate *	isolate,
		int	frame_limit,
		StackTraceOptions	options = `kDetailed`
	)

static

Grab a snapshot of the current JavaScript execution stack.

Parameters

frame_limit	The maximum number of stack frames we want to capture.
options	Enumerates the set of things we will capture for each StackFrame.

◆ GetFrame()

Local<StackFrame> GetFrame	(	Isolate *	isolate,
		uint32_t	index
	)		const

Returns a StackFrame at a particular index.

◆ GetFrameCount()

int GetFrameCount ( ) const

Returns the number of StackFrames.
