-
addRepoChangeListener
Description copied from interface:ComponentRepositoryAdds a listener for repository Item change.- Specified by:
addRepoChangeListenerin interfaceComponentRepository<Item extends RepositoryItem>
-
removeRepoChangeListener
Description copied from interface:ComponentRepositoryRemoves a listener for repository Item change.- Specified by:
removeRepoChangeListenerin interfaceComponentRepository<Item extends RepositoryItem>
-
addItem
Description copied from interface:ComponentRepositoryThe method adds a new or updates existing Item in the repository. It needs to have all fields set correctly. After this method call is finished a new added item must be available in the component repository. The method adds the item to memory cache and permanent storage.- Specified by:
addItemin interfaceComponentRepository<Item extends RepositoryItem>- Parameters:
item- aItemwith all it's configuration parameters.- Throws:
TigaseDBException
-
addItemNoStore
Description copied from interface:ComponentRepositoryThe method adds a new or updates existing Item. It needs to have all fields set correctly. After this method call is finished a new added item must be available in the component repository. The method adds the item to memory cache but not to a permanent storage.- Specified by:
addItemNoStorein interfaceComponentRepository<Item extends RepositoryItem>- Parameters:
item- aItemwith all it's configuration parameters.
-
allItems
Description copied from interface:ComponentRepositoryReturns a collection with all items stored in the repository.- Specified by:
allItemsin interfaceComponentRepository<Item extends RepositoryItem>- Throws:
TigaseDBException
-
contains
Description copied from interface:ComponentRepositoryThe method checks whether the item is stored in the repository.- Specified by:
containsin interfaceComponentRepository<Item extends RepositoryItem>- Parameters:
key- aStringwith key to search for.- Returns:
- a
booleanvaluetrueif the item exists in the repository orfalseof it does not.
-
destroy
public void destroy()Description copied from interface:ComponentRepositoryMethod destroys this instance of ComponentRepository releasing resources allocated for this instance of ComponentRepository if possible- Specified by:
destroyin interfaceComponentRepository<Item extends RepositoryItem>
-
getDefaults
Deprecated.Description copied from interface:ComponentRepositoryThe method is called to obtain default configuration settings if there are any for this repository implementation The configuration settings are implementation dependent and there are no defaults set by the server. Default settings returned by this method are then saved in the configuration file and presented to the admin for further adjustments.- Specified by:
getDefaultsin interfaceComponentRepository<Item extends RepositoryItem>- Parameters:
defs- is aMapcollection where all repository configuration defaults must be put.params- is aMapcollection with some preset properties for the server. These settings can be used to adjust repository defaults, for example they can contain database connection URL or initial list of virtual domains.
-
getItem
Description copied from interface:ComponentRepositoryThe method returns all item configuration parameters for a key ornullif the item does not exist in the repository.- Specified by:
getItemin interfaceComponentRepository<Item extends RepositoryItem>- Parameters:
key- aStringwith item identifier to search for.- Returns:
- a
Itemfor a given key ornullif the item is not in the repository.
-
getItemInstance
Description copied from interface:ComponentRepositoryCreates a new, uninitialized instance of the repository Item.- Specified by:
getItemInstancein interfaceComponentRepository<Item extends RepositoryItem>- Returns:
- a new, uninitialized instance of the repository Item.
-
reload
Description copied from interface:ComponentRepositoryThis method is called to reload items from the database or other permanent storage. It is possible that items list is modified externally by third-party system. When all modifications are done this method is called to refresh the class cache. Whether the implementation load whole list or just last modifications is implementation dependent.- Specified by:
reloadin interfaceComponentRepository<Item extends RepositoryItem>- Throws:
TigaseDBException
-
removeItem
Description copied from interface:ComponentRepositoryThe method is called to remove given Item from the memory cache and permanent storage. After this method is completed the item should no longer be available in the component repository.- Specified by:
removeItemin interfaceComponentRepository<Item extends RepositoryItem>- Parameters:
key- aStringwith domain name to remove.- Throws:
TigaseDBException
-
removeItemNoStore
- Specified by:
removeItemNoStorein interfaceComponentRepository<Item extends RepositoryItem>
-
setProperties
Deprecated.Description copied from interface:ComponentRepositoryThe method is called to set configuration for this repository implementation. The configuration is repository implementation dependent. There are no default settings for the repository.- Specified by:
setPropertiesin interfaceComponentRepository<Item extends RepositoryItem>- Parameters:
properties- aMapwith configuration settings. Content of thisMapmust not be modified. This read-only collection.
-
size
public int size()Description copied from interface:ComponentRepositoryThe method returns number of items in the repository.- Specified by:
sizein interfaceComponentRepository<Item extends RepositoryItem>- Returns:
- an
intvalue with number of items in the repository.
-
store
Description copied from interface:ComponentRepositoryThe method is called to store all data in the database. It is used when the repository has been changed in some way and the changes have to be put to a permanent storage for later retrieval.- Specified by:
storein interfaceComponentRepository<Item extends RepositoryItem>- Throws:
TigaseDBException
-
validateItem
Description copied from interface:ComponentRepositoryPerforms Item validation to check whether it meets the repository policy. If validation is successful the method returnsnull, otherwise it returns an error description.- Specified by:
validateItemin interfaceComponentRepository<Item extends RepositoryItem>- Parameters:
item- is anItemobject to perform validation checking upon.- Returns:
nullon success and an error message otherwise.
-
setAutoloadTimer
public void setAutoloadTimer(long delay) Description copied from interface:ComponentRepositorySets autoload task to periodically reload data from database.- Specified by:
setAutoloadTimerin interfaceComponentRepository<Item extends RepositoryItem>- Parameters:
delay- in seconds between each database reload.
-
iterator
- Specified by:
iteratorin interfaceIterable<Item extends RepositoryItem>
-
initRepository
Description copied from interface:RepositoryMethod is deprecated and should not be user any more.
The method is called to initialize the data repository. Depending on the implementation all the initialization parameters can be passed either viaresource_uriparameter as the database connection string or viaparamsmap if the required repository parameters are more complex or both.- Specified by:
initRepositoryin interfaceRepository- Parameters:
resource_uri- value in most cases representing the database connection string.params- is aMapwith repository properties necessary to initialize and perform all the functions. The initialization parameters are implementation dependent.- Throws:
DBInitException- if there was an error during repository initialization. Some implementations, though, perform so called lazy initialization so even though there is a problem with the underlying repository it may not be signaled through this method call.
