ACE_Sample_History::ACE_Sample_History ( size_t  max_samples)

Constructor.

The number of samples is pre-allocated, and cannot changes once the class is initialized.

ACE_Sample_History::~ACE_Sample_History ( void  )

Destructor.

Member Function Documentation

void ACE_Sample_History::collect_basic_stats ( ACE_Basic_Stats stats) const

Collect the summary for all the samples.

void ACE_Sample_History::dump_samples ( const ACE_TCHAR msg,
ACE_Sample_History::scale_factor_type  scale_factor 
) const

Dump all the samples.

Prints out all the samples, using msg as a prefix for each message.

ACE_UINT64 ACE_Sample_History::get_sample ( size_t  i) const
inline

Get a sample.

size_t ACE_Sample_History::max_samples ( void  ) const
inline

Returns the maximum number of samples.

int ACE_Sample_History::sample ( ACE_UINT64  value)
inline

Record one sample.

Return 0 on success, -1 if the sample could not be stored

size_t ACE_Sample_History::sample_count ( void  ) const
inline

Returns the current number of samples.
