A subgraph, rooted by a BranchGroup node can be thought of as a compile unit. The following things may be done with BranchGroup: <P><UL> <LI>A BranchGroup may be compiled by calling its compile method. This causes the entire subgraph to be compiled. If any BranchGroup nodes are contained within the subgraph, they are compiled as well (along with their descendants).</LI> <p> <LI>A BranchGroup may be inserted into a virtual universe by attaching it to a Locale. The entire subgraph is then said to be live.</LI> <p> <LI>A BranchGroup that is contained within another subgraph may be reparented or detached at run time if the appropriate capabilities are set.</LI> </UL> Note that that if a BranchGroup is included in another subgraph, as a child of some other group node, it may not be attached to a Locale.<P><P><DL><DT><B>Version:</B><DD>1.53, 02/04/01
