Methods of AdaptiveLru:

Methods of Namable:

AdaptiveLru
AdaptiveLru::AdaptiveLru(string const &name, unsigned int max_size);

Description:

beginEpoch
void AdaptiveLru::begin_epoch(void);

Description: Marks the end of the previous epoch and the beginning of the next one. This will evict any objects that are pending eviction, and also update any internal bookkeeping.

considerEvict
void AdaptiveLru::consider_evict(void);

Description: Evicts a sequence of objects if the queue is full.

countActiveSize
unsigned int AdaptiveLru::count_active_size(void) const;

Description: Returns the total size of the pages that were enqueued since the last call to begin_epoch().

evictTo
void AdaptiveLru::evict_to(unsigned int target_size);

Description: Evicts a sequence of objects until the queue fits within the indicated target size, regardless of its normal max size.

getMaxSize
unsigned int AdaptiveLru::get_max_size(void) const;

Description: Returns the max size of all objects that are allowed to be active on the LRU.

getMaxUpdatesPerFrame
int AdaptiveLru::get_max_updates_per_frame(void) const;

Description: Returns the maximum number of pages the AdaptiveLru will update each frame.

getTotalSize
unsigned int AdaptiveLru::get_total_size(void) const;

Description: Returns the total size of all objects currently active on the LRU.

getWeight
float AdaptiveLru::get_weight(void) const;

The following methods are specific to AdaptiveLru, and do not exist in the SimpleLru implementation. In most cases, the defaults will be sufficient, so you do not need to mess with them.
Description: Returns the weight value used to compute the exponential moving average.

output
void AdaptiveLru::output(ostream &out) const;

Description:

setMaxSize
void AdaptiveLru::set_max_size(unsigned int max_size);

Description: Changes the max size of all objects that are allowed to be active on the LRU.
If the size is (size_t)-1, there is no limit.

setMaxUpdatesPerFrame
void AdaptiveLru::set_max_updates_per_frame(int max_updates_per_frame);

Description: Specifies the maximum number of pages the AdaptiveLru will update each frame. This is a performance optimization: keeping this number low limits the impact of the AdaptiveLru's adaptive algorithm.

setWeight
void AdaptiveLru::set_weight(float weight);

The following methods are specific to AdaptiveLru, and do not exist in the SimpleLru implementation. In most cases, the defaults will be sufficient, so you do not need to mess with them.
Description: Specifies the weight value used to compute the exponential moving average.

validate
bool AdaptiveLru::validate(void);

Description: Checks that the LRU is internally self-consistent. Returns true if successful, false if there is some problem.

write
void AdaptiveLru::write(ostream &out, int indent_level) const;

Description:

Namable
Namable::Namable(string const &initial_name = (""));

Description:

clearName
void Namable::clear_name(void);

Description: Resets the Namable's name to empty.

getClassType
static TypeHandle Namable::get_class_type(void);

Undocumented function.

getName
string const &Namable::get_name(void) const;

Description:

hasName
bool Namable::has_name(void) const;

Description: Returns true if the Namable has a nonempty name set, false if the name is empty.

operator =
Namable &Namable::operator =(Namable const &other);

Description:

output
void Namable::output(ostream &out) const;

In the absence of any definition to the contrary, outputting a Namable will write out its name.
Description: Outputs the Namable. This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

setName
void Namable::set_name(string const &name);

Description:
