Detailed Description

CpuProfileNode represents a node in a call graph.

Member Function Documentation

◆ GetBailoutReason()

const char* v8::CpuProfileNode::GetBailoutReason ( ) const

Returns bailout reason for the function if the optimization was disabled for it.

◆ GetChild()

const CpuProfileNode* v8::CpuProfileNode::GetChild ( int  index) const

Retrieves a child node by index.

◆ GetChildrenCount()

int v8::CpuProfileNode::GetChildrenCount ( ) const

Returns child nodes count of the node.

◆ GetColumnNumber()

int v8::CpuProfileNode::GetColumnNumber ( ) const

Returns 1-based number of the column where the function originates. kNoColumnNumberInfo if no column number information is available.

◆ GetDeoptInfos()

const std::vector<CpuProfileDeoptInfo>& v8::CpuProfileNode::GetDeoptInfos ( ) const

Retrieves deopt infos for the node.

◆ GetFunctionName()

Local<String> v8::CpuProfileNode::GetFunctionName ( ) const

Returns function name (empty string for anonymous functions.)

◆ GetFunctionNameStr()

const char* v8::CpuProfileNode::GetFunctionNameStr ( ) const

Returns function name (empty string for anonymous functions.) The string ownership is not passed to the caller. It stays valid until profile is deleted. The function is thread safe.

◆ GetHitCount()

unsigned v8::CpuProfileNode::GetHitCount ( ) const

Returns the count of samples where the function was currently executing.

◆ GetHitLineCount()

unsigned int v8::CpuProfileNode::GetHitLineCount ( ) const

Returns the number of the function's source lines that collect the samples.

◆ GetLineNumber()

int v8::CpuProfileNode::GetLineNumber ( ) const

Returns the number, 1-based, of the line where the function originates. kNoLineNumberInfo if no line number information is available.

◆ GetLineTicks()

bool v8::CpuProfileNode::GetLineTicks ( LineTick entries,
unsigned int  length 
) const

Returns the set of source lines that collect the samples. The caller allocates buffer and responsible for releasing it. True if all available entries are copied, otherwise false. The function copies nothing if buffer is not large enough.

◆ GetNodeId()

unsigned v8::CpuProfileNode::GetNodeId ( ) const

Returns id of the node. The id is unique within the tree

◆ GetScriptId()

int v8::CpuProfileNode::GetScriptId ( ) const

Returns id of the script where function is located.

◆ GetScriptResourceName()

Local<String> v8::CpuProfileNode::GetScriptResourceName ( ) const

Returns resource name for script from where the function originates.

◆ GetScriptResourceNameStr()

const char* v8::CpuProfileNode::GetScriptResourceNameStr ( ) const

Returns resource name for script from where the function originates. The string ownership is not passed to the caller. It stays valid until profile is deleted. The function is thread safe.

◆ V8_DEPRECATE_SOON()

v8::CpuProfileNode::V8_DEPRECATE_SOON ( "Use  GetScriptId,
GetLineNumber  ,
and GetColumnNumber instead."  ,
unsigned GetCallUid()  const 
)

Returns function entry UID.
