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>, Repository

public class VHostJDBCRepository
extends UserRepoRepository<VHostItem>

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.

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

getConfigKey

public String getConfigKey()

Description copied from class: ConfigRepository

Method description

Specified by:

getConfigKey in class ConfigRepository<VHostItem>

getDefaultPropetyItems

public String[] getDefaultPropetyItems()

Description copied from class: ConfigRepository

Method description

Specified by:

getDefaultPropetyItems in class ConfigRepository<VHostItem>

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<VHostItem>

Overrides:

getDefaults in class UserRepoRepository<VHostItem>

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.

getItemInstance

public VHostItem getItemInstance()

Description copied from interface: ComponentRepository

Creates a new, uninitialized instance of the repository Item.

Returns:

a new, uninitialized instance of the repository Item.

getItemsListPKey

public String getItemsListPKey()

Description copied from class: UserRepoRepository

Method description

Overrides:

getItemsListPKey in class UserRepoRepository<VHostItem>

getPropertyKey

public String getPropertyKey()

Description copied from class: ConfigRepository

Method description

Specified by:

getPropertyKey in class ConfigRepository<VHostItem>

getRepoUser

public tigase.xmpp.BareJID getRepoUser()

Description copied from class: UserRepoRepository

Method description

Specified by:

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.

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.

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

Description copied from class: UserRepoRepository

Method description

Specified by:

setProperties in interface ComponentRepository<VHostItem>

Overrides:

setProperties in class UserRepoRepository<VHostItem>

Parameters:

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

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.

Simple verification of VHost validation

Parameters:

args -
