Method Detail

destroy

public void destroy()

Description copied from interface: ComponentRepository

Method destroys this instance of ComponentRepository releasing resources allocated for this instance of ComponentRepository if possible

Specified by:

destroy in interface ComponentRepository<ClusterRepoItem>

getDefaultPropetyItems

public String[] getDefaultPropetyItems()

Description copied from class: ConfigRepository

Method description

Specified by:

getDefaultPropetyItems in class ConfigRepository<ClusterRepoItem>

getName

public String getName()

Specified by:

getName in interface ShutdownHook

getPropertyKey

public String getPropertyKey()

Description copied from class: ConfigRepository

Method description

Specified by:

getPropertyKey in class ConfigRepository<ClusterRepoItem>

getConfigKey

public String getConfigKey()

Description copied from class: ConfigRepository

Method description

Specified by:

getConfigKey in class ConfigRepository<ClusterRepoItem>

getItemInstance

public ClusterRepoItem getItemInstance()

Description copied from interface: ComponentRepository

Creates a new, uninitialized instance of the repository Item.

Specified by:

getItemInstance in interface ComponentRepository<ClusterRepoItem>

Returns:

a new, uninitialized instance of the repository Item.

initRepository

public void initRepository(String resource_uri,
                           Map<String,String> params)
                    throws DBInitException

Description copied from interface: Repository

The method is called to initialize the data repository. Depending on the implementation all the initialization parameters can be passed either via resource_uri parameter as the database connection string or via params map if the required repository parameters are more complex or both.

Specified by:

initRepository in interface Repository

Parameters:

resource_uri - value in most cases representing the database connection string.

params - is a Map with 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.

reload

public void reload()

Description copied from interface: ComponentRepository

This 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:

reload in interface ComponentRepository<ClusterRepoItem>

Overrides:

reload in class ConfigRepository<ClusterRepoItem>

itemLoaded

public void itemLoaded(ClusterRepoItem item)

itemChanged

public boolean itemChanged(ClusterRepoItem oldItem,
                           ClusterRepoItem newItem)

Description copied from class: ConfigRepository

Method description

Overrides:

itemChanged in class ConfigRepository<ClusterRepoItem>

getDefaults

public void getDefaults(Map<String,Object> defs,
                        Map<String,Object> params)

Description copied from interface: ComponentRepository

The 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:

getDefaults in interface ComponentRepository<ClusterRepoItem>

Overrides:

getDefaults in class ConfigRepository<ClusterRepoItem>

Parameters:

defs - is a Map collection where all repository configuration defaults must be put.

params - is a Map collection 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.

setProperties

public void setProperties(Map<String,Object> props)

Description copied from interface: ComponentRepository

The 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:

setProperties in interface ComponentRepository<ClusterRepoItem>

Overrides:

setProperties in class ConfigRepository<ClusterRepoItem>

Parameters:

props - a Map with configuration settings. Content of this Map must not be modified. This read-only collection.

shutdown

public String shutdown()

Specified by:

shutdown in interface ShutdownHook

storeItem

public void storeItem(ClusterRepoItem item)
