Method Detail

getUserProvider

public static UserProvider getUserProvider()

Returns the currently-installed UserProvider. Warning: in virtually all cases the user provider should not be used directly. Instead, the appropriate methods in UserManager should be called. Direct access to the user provider is only provided for special-case logic.

Returns:

the current UserProvider.

getInstance

public static UserManager getInstance()

Returns a singleton UserManager instance.

Returns:

a UserManager instance.

createUser

public User createUser(String username,
                       String password,
                       String name,
                       String email)
                throws UserAlreadyExistsException

Creates a new User. Required values are username and password. The email address and name can optionally be null, unless the UserProvider deems that either of them are required.

Parameters:

username - the new and unique username for the account.

password - the password for the account (plain text).

name - the name of the user, which can be null unless the UserProvider deems that it's required.

email - the email address to associate with the new account, which can be null, unless the UserProvider deems that it's required.

Returns:

a new User.

Throws:

UserAlreadyExistsException - if the username already exists in the system.

UnsupportedOperationException - if the provider does not support the operation.

deleteUser

public void deleteUser(User user)

Deletes a user (optional operation).

Parameters:

user - the user to delete.

getUser

public User getUser(String username)
             throws UserNotFoundException

Returns the User specified by username.

Parameters:

username - the username of the user.

Returns:

the User that matches username.

Throws:

UserNotFoundException - if the user does not exist.

getUserCount

public int getUserCount()

Returns the total number of users in the system.

Returns:

the total number of users.

getUsers

public Collection<User> getUsers()

Returns an unmodifiable Collection of all users in the system.

Returns:

an unmodifiable Collection of all users.

getUsernames

public Collection<String> getUsernames()

Returns an unmodifiable Collection of usernames of all users in the system.

Returns:

an unmodifiable Collection of all usernames in the system.

getUsers

public Collection<User> getUsers(int startIndex,
                                 int numResults)

Returns an unmodifiable Collection of all users starting at startIndex with the given number of results. This is useful to support pagination in a GUI where you may only want to display a certain number of results per page. It is possible that the number of results returned will be less than that specified by numResults if numResults is greater than the number of records left to display.

Parameters:

startIndex - the beginning index to start the results at.

numResults - the total number of results to return.

Returns:

a Collection of users in the specified range.

getSearchFields

public Set<String> getSearchFields()
                            throws UnsupportedOperationException

Returns the set of fields that can be used for searching for users. Each field returned must support wild-card and keyword searching. For example, an implementation might send back the set {"Username", "Name", "Email"}. Any of those three fields can then be used in a search with the findUsers(Set,String) method.

This method should throw an UnsupportedOperationException if this operation is not supported by the backend user store.

Returns:

the valid search fields.

Throws:

UnsupportedOperationException - if the provider does not support the operation (this is an optional operation).

findUsers

public Collection<User> findUsers(Set<String> fields,
                                  String query)
                           throws UnsupportedOperationException

Searches for users based on a set of fields and a query string. The fields must be taken from the values returned by getSearchFields(). The query can include wildcards. For example, a search on the field "Name" with a query of "Ma*" might return user's with the name "Matt", "Martha" and "Madeline".

This method throws an UnsupportedOperationException if this operation is not supported by the user provider.

Parameters:

fields - the fields to search on.

query - the query string.

Returns:

a Collection of users that match the search.

Throws:

UnsupportedOperationException - if the provider does not support the operation (this is an optional operation).

findUsers

public Collection<User> findUsers(Set<String> fields,
                                  String query,
                                  int startIndex,
                                  int numResults)
                           throws UnsupportedOperationException

Searches for users based on a set of fields and a query string. The fields must be taken from the values returned by getSearchFields(). The query can include wildcards. For example, a search on the field "Name" with a query of "Ma*" might return user's with the name "Matt", "Martha" and "Madeline".

The startIndex and numResults parameters are used to page through search results. For example, if the startIndex is 0 and numResults is 10, the first 10 search results will be returned. Note that numResults is a request for the number of results to return and that the actual number of results returned may be fewer.

This method should throw an UnsupportedOperationException if this operation is not supported by the backend user store.

Parameters:

fields - the fields to search on.

query - the query string.

startIndex - the starting index in the search result to return.

numResults - the number of users to return in the search result.

Returns:

a Collection of users that match the search.

Throws:

UnsupportedOperationException - if the provider does not support the operation (this is an optional operation).

isRegisteredUser

public boolean isRegisteredUser(String username)

Returns true if the specified local username belongs to a registered local user.

Parameters:

username - to username of the user to check it it's a registered user.

Returns:

true if the specified JID belongs to a local registered user.

isRegisteredUser

public boolean isRegisteredUser(org.xmpp.packet.JID user)

Returns true if the specified JID belongs to a local or remote registered user. For remote users (i.e. domain does not match local domain) a disco#info request is going to be sent to the bare JID of the user.

Parameters:

user - to JID of the user to check it it's a registered user.

Returns:

true if the specified JID belongs to a local or remote registered user.
