class cache §

Read-only cache.

Parameters

```
typename Key
```
The type of key for looking up a value in the cache.
```
typename Value
```
The type of value stored in the cache.
```
typename LUtime
```
The type to use for storing the time a cache entry was most recently used. Using a wider type makes LRU eviction more accurate for a set associative cache, but for a direct cache where LRU does not apply, using uint1 saves space.
```
auto Associativity
```
The number of entries to store for a given hash value. Use 1 to create a directly mapped cache.
```
auto Depth
```
The total number of entries to cache. Must be a multiple of Associativity.
```
auto Banks = 1
```
The number of memories used to implement the data store. Higher values makes of large caches placement easier.

Aliases

using set_index_t = index_t<cache::_setCount> §

Callbacks and Fields

```
(Key) -> Value load §
```
The callback function to invoke when a get call causes a cache miss.

Methods

```
void initialize() §
```
Initialize or re-initialize a cache object. Re-initializing the cache invalidates all entries. The caller must ensure that intialize is not called concurrently with get.

Value get(Key key, cache::set_index_t set_index) §

Get a value from the cache.
