| MemoryRealm | | public class MemoryRealm extends RealmBase (Code) | | Simple implementation of Realm that reads an XML file to configure
the valid users, passwords, and roles. The file format (and default file
location) are identical to those currently supported by Tomcat 3.X.
IMPLEMENTATION NOTE: It is assumed that the in-memory
collection representing our defined users (and their roles) is initialized
at application startup and never modified again. Therefore, no thread
synchronization is performed around accesses to the principals collection.

| addUser | | void addUser(String username, String password, String roles)(Code) | | Add a new user to the in-memory database.
Parameters:
username - User's username
Parameters:
password - User's password (clear text)
Parameters:
roles - Comma-delimited set of roles associated with this user |
| authenticate | | public Principal authenticate(String username, String credentials)(Code) | | Return the Principal associated with the specified username and
credentials, if there is one; otherwise return null.
Parameters:
username - Username of the Principal to look up
Parameters:
credentials - Password or other credentials to use inauthenticating this username |
| getDigester | | protected synchronized Digester getDigester()(Code) | | Return a configured Digester to use for processing
the XML input file, creating a new one if necessary.
|
| getInfo | | public String getInfo()(Code) | | Return descriptive information about this Realm implementation and
the corresponding version number, in the format
<description>/<version>.
