Class Rank

java.lang.Object
  org.mmbase.security.Rank

All Implemented Interfaces:

Comparable, Serializable

public final class Rank

extends Object

implements Comparable, Serializable

This class defines Rank objects which are used in security implementation. Ranks can be associated with users. Every Rank has an unique integer 'height' (so every rank is higher or lower than any other rank) and a String which can be used to identify it. Possible Ranks are maintained by static methods in this class. Generally the 'anonymous', 'basic user' and 'adminstrator' ranks should always be available, and only be delete with good reason.

Method Detail

getInt

public int getInt()

This method gives back the internal int value of the rank which can be used in switch statements

Returns:

the internal int value

toString

public String toString()

Returns:

a string containing the description of the rank

getRank

public static Rank getRank(String rankDesc)

registerRank

protected static Rank registerRank(Rank rank)

Since:

MMBase-1.6.4

createRank

public static Rank createRank(int rank,
                              String rankDesc)

Creates and adds a new Rank for the security system.

Since:

MMBase-1.6.4

deleteRank

public static Rank deleteRank(String rankDesc)

Removes a rank from the security system.

Since:

MMBase-1.6.4

getRanks

public static SortedSet getRanks()

Returns all ranks currently known by the security implemetation. Default and to start with there are three ranks available: 'anonymous', 'basic user' and 'administrator'. You probably should never remove them.
