SysVCacheItemPool

class SysVCacheItemPool implements CacheItemPoolInterface (View source)

SystemV shared memory based CacheItemPool implementation.

This CacheItemPool implementation can be used among multiple processes, but it doesn't provide any locking mechanism. If multiple processes write to this ItemPool, you have to avoid race condition manually in your code.

Constants

VAR_KEY

DEFAULT_PROJ

DEFAULT_MEMSIZE
