Detailed Description

Generate a unique, increasing time value.

TimeStamp records a unique time when the method Modified() is executed. This time is guaranteed to be monotonically increasing. Classes use this object to record modified and/or execution time. There is built in support for the binary < and > comparison operators between two TimeStamp objects.

Constructor & Destructor Documentation

itk::TimeStamp::TimeStamp (   )  [inline]

Constructor must remain public because classes instantiate TimeStamps implicitly in their construction. Definition at line 51 of file itkTimeStamp.h.

Member Function Documentation

void itk::TimeStamp::Delete (   )  [inline]

Destoy this instance. Definition at line 55 of file itkTimeStamp.h.

unsigned long int itk::TimeStamp::GetMTime (  void   )  const [inline]

Return this object's Modified time. Definition at line 72 of file itkTimeStamp.h.

const char* itk::TimeStamp::GetNameOfClass (   )  [inline, static]

The class name as a string. Definition at line 59 of file itkTimeStamp.h.

void itk::TimeStamp::Modified (   )

Set this objects time to the current time. The current time is just a monotonically increasing unsigned long integer. It is possible for this number to wrap around back to zero. This should only happen for processes that have been running for a very long time, while constantly changing objects within the program. When this does occur, the typical consequence should be that some filters will update themselves when really they don't need to. Referenced by itk::MatrixOffsetTransformBase< TScalarType, 3, 3 >::GetVarInverseMatrix().

Self* itk::TimeStamp::New (   )  [static]

Create an instance of this class. We don't want to use reference counting.

itk::TimeStamp::operator unsigned long (   )  const [inline]

Allow for typcasting to unsigned long. Definition at line 83 of file itkTimeStamp.h.

int itk::TimeStamp::operator< (  TimeStamp &  ts  )  [inline]

Support comparisons of time stamp objects directly. Definition at line 78 of file itkTimeStamp.h. References m_ModifiedTime.

int itk::TimeStamp::operator> (  TimeStamp &  ts  )  [inline]

Support comparisons of time stamp objects directly. Definition at line 76 of file itkTimeStamp.h. References m_ModifiedTime.
