[jira] [Updated] (GIRAPH-586) Customizable default vertex value

     [ https://issues.apache.org/jira/browse/GIRAPH-586?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alessandro Presta updated GIRAPH-586:
-------------------------------------

    Attachment: GIRAPH-586.patch

Adds a VertexValueFactory that can be optionally specified by the user.
It's initialized with the configuration.
DefaultVertexValueFactory implements the current behavior (caches the vertex value class and uses reflection).

> When Giraph implicitly adds a vertex (e.g., during edge-based input or mutations), the vertex value is created using reflection, so it is default-initialized (e.g., a double will be 0.0).
> For some algorithms, the default value might be something different, or even need to be read from the configuration at run-time.
