[jira] [Commented] (JENA-2336) DatasetGraphBase.toString does not scale (for debugging)

["Andy Seaborne (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-2336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17563980#comment-17563980 ] 

Andy Seaborne commented on JENA-2336:
-------------------------------------

Will you be contributing a PR to address this?

{{DatasetGraphBase}} is an abstract class. What is the implementation class?

The implementation will know the best way to handle this.  {{DatasetGraphBase}} provides a minimal implementation.

> When I am debugging Jena-based code and mouse-over a dataset variable, the system basically hangs. It seems that the toString() method of DatasetGraphBase is producing a complete rendering of the whole dataset using WriterGraph.output(out, this, null). And our datasets typically contain thousands of named graphs, some of which are quite large. 
> This is handled much better in places such as GraphBase.toString, which terminates after a certain number of triples.
