## Member Function Documentation

vtkThreadSafeLog* vtkThreadSafeLog::New | ( |  | ) | `[static]`

| Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

virtual const char* vtkThreadSafeLog::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkObject.

int vtkThreadSafeLog::IsTypeOf | ( | const char * | type | ) | `[static]`

| Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkObject.

virtual int vtkThreadSafeLog::IsA | ( | const char * | type | ) | `[virtual]`

| Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkObject.

vtkThreadSafeLog* vtkThreadSafeLog::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkObject.

virtual void vtkThreadSafeLog::PrintSelf | ( | ostream & | os,
|  | vtkIndent | indent
| ) | `[virtual]`

| Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkObject.

void vtkThreadSafeLog::StartTimer | ( |  | ) | `[inline]`

| some of the timeing features of vtkTimerLog. Definition at line 52 of file vtkThreadSafeLog.h.

void vtkThreadSafeLog::StopTimer | ( |  | ) | `[inline]`

| some of the timeing features of vtkTimerLog. Definition at line 53 of file vtkThreadSafeLog.h.

double vtkThreadSafeLog::GetElapsedTime | ( |  | ) | `[inline]`

| some of the timeing features of vtkTimerLog. Definition at line 54 of file vtkThreadSafeLog.h.

void vtkThreadSafeLog::AddEntry | ( | char * | tag,
|  | float | value
| ) |

| Save a tag/value pair.

void vtkThreadSafeLog::DumpLog | ( | char * | filename,
|  | int | mode = ios::out
| ) |

| Write the timing table out to a file. if mode is out, then two lines are printed: Tags on first, values on second. If mode is iso::app, then only the line with values is printed.
