CpuProfileNode represents a node in a call graph.
Definition at line 52 of file v8-profiler.h.
const char* GetBailoutReason | ( | ) | const |
Returns bailout reason for the function if the optimization was disabled for it.
unsigned GetCallUid | ( | ) | const |
Returns function entry UID.
const CpuProfileNode* GetChild | ( | int | index | ) | const |
Retrieves a child node by index.
int GetChildrenCount | ( | ) | const |
Returns child nodes count of the node.
int GetColumnNumber | ( | ) | const |
Returns 1-based number of the column where the function originates. kNoColumnNumberInfo if no column number information is available.
const std::vector<CpuProfileDeoptInfo>& GetDeoptInfos | ( | ) | const |
Retrieves deopt infos for the node.
Returns function name (empty string for anonymous functions.)
unsigned GetHitCount | ( | ) | const |
Returns the count of samples where the function was currently executing.
unsigned int GetHitLineCount | ( | ) | const |
Returns the number of the function's source lines that collect the samples.
int GetLineNumber | ( | ) | const |
Returns the number, 1-based, of the line where the function originates. kNoLineNumberInfo if no line number information is available.
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.
unsigned GetNodeId | ( | ) | const |
Returns id of the node. The id is unique within the tree
int GetScriptId | ( | ) | const |
Returns id of the script where function is located.
Returns resource name for script from where the function originates.
