Constructor & Destructor Documentation

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.
