Subject [jira] [Commented] (GIRAPH-83) Is Vertex correct yet?
Date Thu, 17 Nov 2011 21:49:53 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-83?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13152373#comment-13152373

Jake Mannix commented on GIRAPH-83:
-----------------------------------

bq. In that Vertex is responsible for maintaining the destEdgeMap for an implementation of
Vertex, rather than implementers having to do this themselves. For each compute invocation,
the vertex shouldn't assume anything about its outgoing edges, as they may have been mutated
since the last call.

You mean that in the current Vertex class, we have the map of edges right there?  It's not
really in the framework, it's in the superclass, but ok, you're saying we *shouldn't* take
care of the bookkeeping about this, and leave it always up to the implementations (like the
way that LongDoubleFloatDoubleVertex does it with primitives)?  Or that there should be some
other structure which handles them?
