Member Function Documentation

add_num_states()

void CacheStats::add_num_states ( int count )

inline

Adds the indicated count (positive or negative) to the total count of individual RenderState or TransformState objects.

Definition at line 90 of file cacheStats.I.

add_total_size()

void CacheStats::add_total_size ( int count )

inline

Adds the indicated count (positive or negative) to the total number of entries for the cache (net occupied size of all the hashtables).

Definition at line 79 of file cacheStats.I.

inc_adds()

void CacheStats::inc_adds ( bool is_new )

inline

Increments by 1 the count of elements added to the cache.

If is_new is true, the element was added to a previously empty hashtable.

Definition at line 55 of file cacheStats.I.

inc_dels()

void CacheStats::inc_dels ( )

inline

Increments by 1 the count of elements removed from the cache.

Definition at line 68 of file cacheStats.I.

inc_hits()

void CacheStats::inc_hits ( )

inline

Increments by 1 the count of cache hits.

Definition at line 34 of file cacheStats.I.

inc_misses()

void CacheStats::inc_misses ( )

inline

Increments by 1 the count of cache misses.

Definition at line 44 of file cacheStats.I.

init()

void CacheStats::init

(

)

Initializes the CacheStats for the first time.

We don't use the constructor for this, since we can't guarantee ordering of static constructors.

Definition at line 21 of file cacheStats.cxx.

maybe_report()

void CacheStats::maybe_report ( const char * name )

inline

Outputs a report if enough time has elapsed.

Definition at line 17 of file cacheStats.I.

References ClockObject::get_global_clock(), ClockObject::get_real_time, Notify::out(), and reset().

reset()

void CacheStats::reset

(

double

now

)

Reinitializes just those parts of the CacheStats that should be reset between each reporting interval.

Definition at line 36 of file cacheStats.cxx.

Referenced by maybe_report().

write()

void CacheStats::write	(	std::ostream &	out,
		const char *	name ) const
