## be.ehealth.technicalconnector.cache
Interface Cache<K,V>

All Known Implementing Classes:
  HashMapCache, JSR107Cache

    public interface Cache<K,V>

A cache is similar to a map or a key value store, allowing to retrieve and update values which are associated to keys.

Field Summary
`static String` | `CACHE_EXPIRY_DURATION`
`static String` | `CACHE_EXPIRY_TYPE`
`static String` | `CACHE_NAME`

Method Summary
`void` | `clear()` Clear the cache.
`boolean` | `containsKey(K key)` Returns true, if there is a mapping for the specified key.
`V` | `get(K key)` Returns a value associated by the given key, that contains a non expired value.
`String` | `getName()` A configured or generated name of this cache instance.
`void` | `put(K key, V value)` Updates an existing cache entry for the specified key, so it associates the given value, or, insert a new cache entry for this key and value.
`void` | `putAll(Map<K,V> keystores)`
`void` | `remove(K key)` Removes the mapping for a key from the cache if it is present.

    String getName()

  A configured or generated name of this cache instance.

  Returns:
    name of this cache or null for anonymous caches.

### get

### containsKey

    boolean containsKey(K key)

  Returns true, if there is a mapping for the specified key.

  Parameters:
    `key` - key which association should be checked
  Returns:
    `true`, if this cache contains a mapping for the specified key

### put

    void put(K key,
             V value)

  Updates an existing cache entry for the specified key, so it associates the given value, or, insert a new cache entry for this key and value.

  Parameters:
    `key` - key with which the specified value is associated
    `value` - value to be associated with the specified key

### remove

    void remove(K key)

  Removes the mapping for a key from the cache if it is present.

  Parameters:
    `key` - key which mapping is to be removed from the cache, not null

### clear
