Detailed Description

Save multiple samples in an array.

Save multiple samples (usually latency numbers), into an array, and later print them in several formats.

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.

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_UINT32	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

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

Returns the current number of samples.

The maximum number of samples.

The current number of samples.

The samples.
