Detailed Description

template<class T>
class MEM_CacheLimiter< T >

MEM_CacheLimiter

This class defines a generic memory cache management system to limit memory usage to a fixed global maximum.

Note

Please use the C-API in MEM_CacheLimiterC-Api.h for code written in C.

Usage example:

class BigFatImage {
public:
      ~BigFatImage() { tell_everyone_we_are_gone(this); }
};
 
void doit()
{
    MEM_Cache<BigFatImage> BigFatImages;
 
    MEM_Cache_Handle<BigFatImage>* h = BigFatImages.insert(new BigFatImage);
 
    BigFatImages.enforce_limits();
    h->ref();
 
    // work with image...
 
    h->unref();
 
    // leave image in cache.
