Method Detail

loadUser

User loadUser(String username)
              throws UserNotFoundException

Loads the specified user by username.

Parameters:

username - the username

Returns:

the User.

UserNotFoundException - if the User could not be loaded.

createUser

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

email - the user's email address, which can be null, unless isEmailRequired is set to true.

Returns:

a new User.

UserAlreadyExistsException - if the username is already in use.

deleteUser

void deleteUser(String username)

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

Parameters:

username - the username to delete.

getUserCount

int getUserCount()

Returns the number of users in the system.

Returns:

the total number of users.

getUsers

Collection<User> getUsers()

Returns an unmodifiable Collections of all users in the system. The UserCollection class can be used to assist in the implementation of this method. It takes a String [] of usernames and presents it as a Collection of User objects (obtained with calls to UserManager.getUser(String).

Returns:

an unmodifiable Collection of all users.

getUsernames

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

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

Returns an unmodifiable Collections of users in the system within the specified range. The UserCollection class can be used to assist in the implementation of this method. It takes a String [] of usernames and presents it as a Collection of User objects (obtained with calls to UserManager.getUser(String).

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:

an unmodifiable Collection of users within the specified range.

setName

void setName(String username,
             String name)
             throws UserNotFoundException

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

Parameters:

username - the username.

name - the name.

Throws:

UserNotFoundException - if the user could not be found.

setEmail

void setEmail(String username,
              String email)
              throws UserNotFoundException

Sets the user's email address. This method should throw an UnsupportedOperationException if this operation is not supported by the backend user store.

Parameters:

username - the username.

email - the email address.

Throws:

UserNotFoundException - if the user could not be found.

setCreationDate

void setCreationDate(String username,
                     Date creationDate)
                     throws UserNotFoundException

Parameters:

username - the username.

creationDate - the date the user was created.

Throws:

UserNotFoundException - if the user could not be found.

setModificationDate

void setModificationDate(String username,
                         Date modificationDate)
                         throws UserNotFoundException

Sets the date the user was last modified. This method should throw an UnsupportedOperationException if this operation is not supported by the backend user store.

Parameters:

username - the username.

modificationDate - the date the user was last modified.

Throws:

UserNotFoundException - if the user could not be found.

getSearchFields

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

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 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.

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

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).

isReadOnly

boolean isReadOnly()

Returns true if this UserProvider is read-only. When read-only, users can not be created, deleted, or modified.

Returns:

true if the user provider is read-only.

isNameRequired

boolean isNameRequired()

Returns true if this UserProvider requires a name to be set on User objects.

Returns:

true if an name is required with this provider.

isEmailRequired

boolean isEmailRequired()

Returns true if this UserProvider requires an email address to be set on User objects.
