Class UserDirectory

java.lang.Object
com.iizix.server.push.engine.store.UserDirectory
public final class UserDirectory extends Object
The Destination field's lookup: user names and e-mail addresses, case-insensitive, with the * wildcard, resolved to user IDs against IZS.USERS.

Push does not model identity (ruling 2). This class names a user only by UserInfoBase.id and reads the columns that exist for the lookup: user_name_lower and email. The SQL is LIKE ... ESCAPE '!' with LOWER() on the e-mail, both SQL-92, portable between Derby and PostgreSQL.
