[jira] [Commented] (TINKERPOP3-611) Messenger.receiveMessages(no args)

["Marko A. Rodriguez (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TINKERPOP3-611?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14489846#comment-14489846 ] 

Marko A. Rodriguez commented on TINKERPOP3-611:
-----------------------------------------------

[~mbroecheler] I would like to do this now that {{VertexProgram.getMessageScopes}} exists and "pull-based message passing" systems can use that to determine which messages to "receive."

> Right now {{Messenger.recieveMessages()}} takes a {{MessageScope}} argument. This is oriented towards "message pulling systems" that require the {{MessageScope}} to know which adjacent vertices to get their messages from. For "message passing systems" this is not needed and in fact, if required, requires some sort of message tagging and non-Iterator behavior.  
> We should get rid of the {{MessageScope}} argument and "message pull systems" can simply get the {{MessageScope}}s from {{VertexProgram.getMessageScopes(iteration)}}.
