## be.ehealth.technicalconnector.service.kgss
Class KgssManager

    java.lang.Object
      be.ehealth.technicalconnector.service.kgss.KgssManager

All Implemented Interfaces:
  SessionServiceWithCache

    public final class KgssManager

extends Object
implements SessionServiceWithCache

Simplifies the usage of KGSS. It allows for caching of KGSS keys and easy requesting of new keys and existing keys from KGSS Web Service

Field Summary
`static String` | `PROP_KGSS_IDENTIFIER_APPLICATIONID` Property to specify the applicationId used by the KGSS Default value: KGSS

Method Summary
`void` | `add(List<CredentialType> allowedReaders, byte[] myEtk)` Requests a new key from KGSS and adds it to the cache
`void` | `add(String cacheId, List<CredentialType> allowedReaders, byte[] myEtk)` Requests a new key from KGSS and adds it to the cache
`boolean` | `containsKey(String key)` Check if the KeyCache contains a certain key, based on the KeyCache ID KeyCache ID's are formatted either: - "(" + keyId + ")" - normal caching - "(" + patientId + "#" + prescriptionType + ")" - prepare prescription keys Returns `true` if this map contains a mapping for the specified key.
`void` | `flushCache()` Flush cache.
`KeyResult` | `get(String keyId, byte[] myEtk)` Gets a key from the KeyCache, if the key is not present in the cache it will be retrieved from the KGSS Web Service and added to the KeyCache. the format of the KeyCache ID searched : keyId
`static KgssManager` | `getInstance()` Gets the single instance of KeyCacheManager.
`static KgssManager` | `getInstance(KgssService kgssService)` Gets the single instance of KeyCacheManager.
`KeyResult` | `getNewKeyFromKgss(List<CredentialType> allowedReaders, byte[] myEtk)` Retrieves a new key from the KGSS Web Service and returns it.
`KeyResult` | `remove(String key)` Removes the mapping for a key from this map if it is present (optional operation).
`void` | `setKgssService(KgssService service)`

Field Detail

### PROP_KGSS_IDENTIFIER_APPLICATIONID

    public static final String PROP_KGSS_IDENTIFIER_APPLICATIONID

  Property to specify the applicationId used by the KGSS

  Default value: KGSS

  See Also:
    Constant Field Values

Method Detail

### getInstance

    public static KgssManager getInstance()

  Gets the single instance of KeyCacheManager.

### getInstance

    public static KgssManager getInstance(KgssService kgssService)

  Gets the single instance of KeyCacheManager.

### get

    public KeyResult get(String keyId,
                         byte[] myEtk)
                  throws TechnicalConnectorException

  Gets a key from the KeyCache, if the key is not present in the cache it will be retrieved from the KGSS Web Service and added to the KeyCache. the format of the KeyCache ID searched : keyId

  Parameters:
    `keyId` - The KeyIdentifier
    `myEtk` - The ETK of the application
  Returns:
    the requested key
  Throws:
    `TechnicalConnectorException` - When a technical exception occurs

### add

    public void add(List<CredentialType> allowedReaders,
                    byte[] myEtk)
             throws TechnicalConnectorException

  Requests a new key from KGSS and adds it to the cache

  Parameters:
    `allowedReaders` - the allowed readers
    `myEtk` - the my etk
  Throws:
    `TechnicalConnectorException` - the technical connector exception

### add

    public void add(String cacheId,
                    List<CredentialType> allowedReaders,
                    byte[] myEtk)
             throws TechnicalConnectorException

  Requests a new key from KGSS and adds it to the cache

  Parameters:
    `cacheId` - the cache id
    `allowedReaders` - the allowed readers
    `myEtk` - the my etk
  Throws:
    `TechnicalConnectorException` - the technical connector exception

### remove

    public KeyResult remove(String key)

  Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key `k` to value `v` such that `(key==null ? k==null : key.equals(k))`, that mapping is removed. (The map can contain at most one such mapping.)

  Returns the value to which this map previously associated the key, or `null` if the map contained no mapping for the key.

  If this map permits null values, then a return value of `null` does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to `null`.

  The map will not contain a mapping for the specified key once the call returns.

  Parameters:
    `key` - key whose mapping is to be removed from the map
  Returns:
    the previous value associated with `key`, or `null` if there was no mapping for `key`.

### containsKey

    public boolean containsKey(String key)

  Check if the KeyCache contains a certain key, based on the KeyCache ID KeyCache ID's are formatted either: - "(" + keyId + ")" - normal caching - "(" + patientId + "#" + prescriptionType + ")" - prepare prescription keys

  Returns `true` if this map contains a mapping for the specified key. More formally, returns `true` if and only if this map contains a mapping for a key `k` such that `(key==null ? k==null : key.equals(k))`. (There can be at most one such mapping.)

  Parameters:
    `key` - the KeyCacheId
  Returns:
    true, if successful

### getNewKeyFromKgss

    public KeyResult getNewKeyFromKgss(List<CredentialType> allowedReaders,
                                       byte[] myEtk)
                                throws TechnicalConnectorException

  Retrieves a new key from the KGSS Web Service and returns it.

  Parameters:
    `allowedReaders` - the allowed readers
    `myEtk` - The ETK of the application
  Returns:
    The generated key from the KGSS Web Service
  Throws:
    `TechnicalConnectorException` - the technical connector exception

### flushCache

    public void flushCache()

  Flush cache.

  Specified by:
    `flushCache` in interface `SessionServiceWithCache`

### setKgssService

    public void setKgssService(KgssService service)

  Parameters:
    `service` - the service to set
