Class UserRepositoryPool

  • All Implemented Interfaces:
    Repository, RepositoryPool<UserRepository>, UserRepository
    public class UserRepositoryPool
extends java.lang.Object
implements UserRepository, RepositoryPool<UserRepository>
    Pool for user repositories. *
    This pool should be used if connection to user storage is blocking or synchronized, ie. implemented using single connection.*
    If implementation of UserRepository uses connection pool or non blocking, concurrent access to user storage (ie. DataSourcePool), then this pool is not need.

        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.

      • userExists

        public boolean userExists​(BareJID user)
        Description copied from interface: UserRepository
        Method userExists checks whether the user (or repository top node) exists in the database. The method doesn't throw any exception nor it creates the user in case it is missing. It just checks whether the user is already in the database.
        Please don't overuse this method. All other methods throw UserNotFoundException exception in case the user is missing for which you executed the method. The exception is thrown unless userAutoCreate property is set to true. In such case the exception is never thrown and the methods are executed for given parameters prior to creating user entry if it is missing.
        Therefore this method should be used only to check whether the account exists without creating it.
        Specified by:
        userExists in interface UserRepository
        Parameters:
        user - a BareJID value
        Returns:
        a boolean value
