Member Function Documentation

◆ GetBailoutReason()

const char* GetBailoutReason ( ) const

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

◆ GetCallUid()

unsigned GetCallUid ( ) const

Returns function entry UID.

◆ GetChild()

const CpuProfileNode* GetChild ( int  index) const

Retrieves a child node by index.

◆ GetChildrenCount()

int GetChildrenCount ( ) const

Returns child nodes count of the node.

◆ GetColumnNumber()

int 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>& GetDeoptInfos ( ) const

Retrieves deopt infos for the node.

◆ GetFunctionName()

Local<String> GetFunctionName ( ) const

Returns function name (empty string for anonymous functions.)

◆ GetHitCount()

unsigned GetHitCount ( ) const

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

◆ GetHitLineCount()

unsigned int GetHitLineCount ( ) const

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

◆ GetLineNumber()

int GetLineNumber ( ) const

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

◆ GetLineTicks()

bool 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 GetNodeId ( ) const

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

◆ GetScriptId()

int GetScriptId ( ) const

Returns id of the script where function is located.

◆ GetScriptResourceName()

Local<String> GetScriptResourceName ( ) const

Returns resource name for script from where the function originates.
