Cache (Jackrabbit Oak 1.62.0 API)

All Known Implementing Classes:

CacheAccessTracker, RecordCache
```
public interface Cache<K,V>
```
Partial mapping of keys of type K to values of type Cache. If supported by the underlying implementation the mappings can further be associated with a cost, which is a metric for the cost occurring when the given mapping is lost. Higher values represent higher costs.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`V`	`get(K key)`
`void`	`put(K key, V value)`	Add a mapping from `key` to `value`.
`void`	`put(K key, V value, byte cost)`	Add a mapping from `key` to `value` with a given `cost`.

- Method Detail
  - put
```
void put(@NotNull
         K key,
         @NotNull
         V value)
```
    Add a mapping from key to value.
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the underlying implementation doesn't support values without an associated cost and put(Object, Object, byte) should be used instead.
  - put
```
void put(@NotNull
         K key,
         @NotNull
         V value,
         byte cost)
```
    Add a mapping from key to value with a given cost.
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the underlying implementation doesn't support values with an associated cost and put(Object, Object) should be used instead.
  - get
```
@Nullable
V get(@NotNull
      K key)
```
    Returns:
    
    The mapping for key, or null if none.
