Field Documentation

cache_limit

size_t RF_HVD_CACHE_PARAMS::cache_limit

The total cache memory limit.

If the cache size exceeds this, the cache implementation will attempt to reduce size by compressing, purging, or removing raster data, as allowed by the implementation. If the limit is zero, the cache size will be read from the HVDCacheLimit parameter of the global configuration. If this limit is also zero, then the cache size is unbounded.

cache_policy

int RF_HVD_CACHE_PARAMS::cache_policy

The cache purging policy.

If the cache needs to reduce size because it exceeeded the cache memory limit, this policy determines which elements will be selected for compressing, purging, or removal first.

See HVD_cache_policy, HVD_cache_policy_values and HVD_PURGE_NEXT for a description of how HVD cache policies are constructed.

port

int RF_HVD_CACHE_PARAMS::port

The port number that the HVD cache will listen on.

If this is 0, then the default HVD cache port will be used. On the central blade, this port is likely to be taken by the Scalable RIP itself, so an alternate port number should be used to host an HVD cache in a different process.
