Grouper Developers Forum

[Chris Hyzer <>]

Hey,

I got clarification of some terms about grouper from Tom and Gary, and I 
updated the Javadoc on a bunch of classes and methods.  Here is the gist of 
what I learned.  Let me know if I should change anything and I am happy to do 
it.

FYI.

Kind regards,

Chris

Immediate member:

   * An immediate member is directly assigned to a group.
   * A composite group has no immediate members.  Note that
   * a member can have an immediate membership and an effective membership.

Effective member:

   * An effective member has an indirect membership to a group
   * (e.g. in a group within a group).  All subjects in a
   * composite group are effective members (since the composite
   * group has two groups and a set operator and no other immediate
   * members).  Note that a member can have an immediate membership
   * and an effective membership.

Composite member:

   * A composite group has two groups as members and a set operator
   * (e.g. union, intersection, etc).  A composite group has no immediate 
members.
   * All subjects in a composite group are effective members.

Member (i.e. group.getMember):

   * All immediate subjects, and effective members are members.
   * No duplicates will be returned (e.g. if immediate and effective).

Membership:

   * A membership is the object which represents a join of member
   * and group.  Has metadata like type and creator.
