Class VHostJDBCRepository

java.lang.Object

tigase.db.comp.ConfigRepository<Item>

tigase.db.comp.UserRepoRepository<VHostItem>

tigase.vhosts.VHostJDBCRepository

All Implemented Interfaces:

Iterable<VHostItem>, ComponentRepository<VHostItem>, ComponentRepositoryDataSourceAware<VHostItem,DataSource>, DataSourceAware<DataSource>, Repository, Initializable, UnregisterAware

@ConfigAliases(@ConfigAlias(field="items",alias="virtual-hosts"))
public class VHostJDBCRepository
extends UserRepoRepository<VHostItem>
implements ComponentRepositoryDataSourceAware<VHostItem,DataSource>

This implementation stores virtual domains in the UserRepository database. It loads initial settings and virtual hosts from the configuration file and then loads more vhosts from the database. Virtual domains from the database can overwrite (disable) vhosts loaded from the configuration file.
This implementation keeps all virtual hosts and their parameters in a single database field. This might not be very efficient if you want to manager big number of virtual domains. It is sufficient for hundreds of vhosts. If you need thousands of VHosts support I advice to implement this storage in more efficient way using separate database tables instead of UserRepository. Please note there is a limit of about 300 vhosts if you use Derby database.

Constructor Detail

VHostJDBCRepository

public VHostJDBCRepository()

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<VHostItem>

getConfigKey

public String getConfigKey()

Specified by:

getConfigKey in class ConfigRepository<VHostItem>

getDefaultPropetyItems

public String[] getDefaultPropetyItems()

Overrides:

getDefaultPropetyItems in class ConfigRepository<VHostItem>

getItemInstance

public VHostItem getItemInstance()

Description copied from interface: ComponentRepository

Creates a new, uninitialized instance of the repository Item.

Specified by:

getItemInstance in interface ComponentRepository<VHostItem>

Returns:

a new, uninitialized instance of the repository Item.

getItemsListPKey

public String getItemsListPKey()

Overrides:

getItemsListPKey in class UserRepoRepository<VHostItem>

getPropertyKey

public String getPropertyKey()

Specified by:

getPropertyKey in class ConfigRepository<VHostItem>

getRepoUser

public BareJID getRepoUser()

Specified by:

getRepoUser in class UserRepoRepository<VHostItem>

initRepository

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

Deprecated.

Description copied from interface: Repository

Method 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 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<VHostItem>

Overrides:

reload in class UserRepoRepository<VHostItem>

setDef_srv_address

public void setDef_srv_address(String address)

validateItem

public String validateItem(VHostItem item)

Description copied from interface: ComponentRepository

Performs Item validation to check whether it meets the repository policy. If validation is successful the method returns null, otherwise it returns an error description.

Specified by:

validateItem in interface ComponentRepository<VHostItem>

Overrides:

validateItem in class ConfigRepository<VHostItem>

Parameters:

item - is an Item object to perform validation checking upon.

Returns:

null on success and an error message otherwise.

setDataSource

public void setDataSource(DataSource dataSource)

Description copied from interface: DataSourceAware

Method called to provide class with instance of a data source.

Specified by:

setDataSource in interface DataSourceAware<DataSource>

getDefaultVHost

public String getDefaultVHost()

setDefaultVHost

public void setDefaultVHost(String vhost)

setItemsOld

public void setItemsOld(String[] items_arr)

Overrides:

setItemsOld in class ConfigRepository<VHostItem>

setVhostDefaults

public void setVhostDefaults(VHostItemDefaults vhostDefaults)
