pure virtual |
Prevent new get() calls from returning the matching entry. If the matching entry is unused, it may be removed from the store now. The store entry is matched using either e attachment info or e.key.
Implemented in Transients, MemStore, Fs::Ufs::UFSSwapDir, Rock::SwapDir, Store::Disks, Store::Controller, and TestSwapDir.
Referenced by Store::Disks::evictCached().
|
pure virtual |
An evictCached() equivalent for callers that did not get() a StoreEntry. Callers with StoreEntry objects must use evictCached() instead.
Implemented in Transients, MemStore, Fs::Ufs::UFSSwapDir, Rock::SwapDir, Store::Disks, Store::Controller, and TestSwapDir.

pure virtual |
Implemented in Transients, TestStore, MemStore, Store::Disk, Store::Controller, and Store::Disks.
|
pure virtual |
Start preparing the store for use. To check readiness, callers should use readable() and writable() methods.
Implemented in Rock::SwapDir, Transients, TestStore, MemStore, Fs::Ufs::UFSSwapDir, Store::Controller, TestSwapDir, and Store::Disks.
|
pure virtual |
Implemented in Rock::SwapDir, Transients, MemStore, TestStore, Store::Disk, Fs::Ufs::UFSSwapDir, Store::Controller, and Store::Disks.

pure virtual |
The maximum size the store will support in normal use. Inaccuracy is permitted, but may throw estimates for memory etc out of whack.
Implemented in Transients, TestStore, MemStore, Store::Disk, Store::Controller, Store::Disks, and TestSwapDir.
