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 111 of file cacheStats.I.

Referenced by RenderState::~RenderState(), and TransformState::~TransformState().

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 97 of file cacheStats.I.

Referenced by TransformState::clear_cache(), and RenderState::clear_cache().

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 67 of file cacheStats.I.

void CacheStats::inc_dels ( ) [inline]

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

Definition at line 83 of file cacheStats.I.

void CacheStats::inc_hits ( ) [inline]

Increments by 1 the count of cache hits.

Definition at line 41 of file cacheStats.I.

void CacheStats::inc_misses ( ) [inline]

Increments by 1 the count of cache misses.

Definition at line 53 of file cacheStats.I.

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 25 of file cacheStats.cxx.

References ClockObject::get_global_clock(), and reset().

Referenced by TransformState::init_states(), and RenderState::init_states().

void CacheStats::maybe_report ( const char *  name) [inline]

Outputs a report if enough time has elapsed.

Definition at line 22 of file cacheStats.I.

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

void CacheStats::reset ( double  now)

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

Definition at line 43 of file cacheStats.cxx.

Referenced by init(), and maybe_report().
