## be.ehealth.technicalconnector.cache.impl
Class HashMapCache<K,V>

    java.lang.Object
      be.ehealth.technicalconnector.cache.impl.HashMapCache<K,V>

All Implemented Interfaces:
  Cache<K,V>, ConfigurableImplementation

    public class HashMapCache<K,V>

extends Object
implements Cache<K,V>, ConfigurableImplementation

Implementation of `Cache` based on a HashMap implementation. Warning Not safe to use in a multi threaded environment.

Field Summary

Constructor Summary
`HashMapCache()`

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` | `initialize(Map<String,Object> parameterMap)` initializes the implementation with additional parameters.
`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> map)`
`void` | `remove(K key)` Removes the mapping for a key from the cache if it is present.

    name of this cache or null for anonymous caches.

### get

    public V get(K key)

  Description copied from interface: `Cache`

  Description copied from interface: `Cache`
  Returns true, if there is a mapping for the specified key.

  Specified by:
    `containsKey` in interface `Cache<K,V>`
  Parameters:
    `key` - key which association should be checked
  Returns:
    `true`, if this cache contains a mapping for the specified key

### put

    public void put(K key,
                    V value)

  Description copied from interface: `Cache`
  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.

  Specified by:
    `put` in interface `Cache<K,V>`
  Parameters:
    `key` - key with which the specified value is associated
    `value` - value to be associated with the specified key

### remove

    public void remove(K key)

  Description copied from interface: `Cache`
  Removes the mapping for a key from the cache if it is present.

  Specified by:
    `remove` in interface `Cache<K,V>`
  Parameters:
    `key` - key which mapping is to be removed from the cache, not null

### clear

    public void clear()

  Description copied from interface: `Cache`
  Clear the cache.

  Specified by:
    `clear` in interface `Cache<K,V>`

### putAll

    public void putAll(Map<K,V> map)

  Specified by:
    `putAll` in interface `Cache<K,V>`

### initialize

    public void initialize(Map<String,Object> parameterMap)
                    throws TechnicalConnectorException

  Description copied from interface: `ConfigurableImplementation`
  initializes the implementation with additional parameters.

  Specified by:
    `initialize` in interface `ConfigurableImplementation`
  Parameters:
    `parameterMap` - Map with for each propertyString ,the input parameter as Object.
