Alessandro Presta created GIRAPH-531:
----------------------------------------
Summary: EdgeIterables#getEdges() should reuse Edge objects
Key: GIRAPH-531
URL: https://issues.apache.org/jira/browse/GIRAPH-531
Project: Giraph
Issue Type: Improvement
Reporter: Alessandro Presta
Assignee: Alessandro Presta
Since some of our vertex implementations don't allow for mutating or keeping
references to edges returned by Vertex#getEdges(), we can consider that part of
the API and exploit it in other places.
EdgeIterables#getEdges() currently creates a new Edge object at each iteration.
We can reuse the object for efficiency.
Note: this issue may become irrelevant depending on how we refactor the Vertex
API (e.g. no distinction between Vertex and SimpleVertex).
