[dna-issues] [JBoss JIRA] Resolved: (DNA-173) Create reusable PathExpression class in the SPI

Wed Jul 9 16:38:26 EDT 2008

     [ http://jira.jboss.com/jira/browse/DNA-173?page=all ]

Randall Hauch resolved DNA-173.
-------------------------------

    Resolution: Done

Moved the path expression functionality out of the SequencerPathExpression (which now contains a PathExpression for the input along with an output expression) and into PathExpression in the SPI.  Added several test cases, including some new cases.  There is no change in the behavior, and all existing test cases still work.

> The SequencerPathExpression has some useful and reusable functionality for representing path-based expressions.  This should be pulled out of the SequencerPathExpression (which would then contain a PathExpression plus an output specification) and moved into the SPI project.
> An example usage is a GraphCommand that retrieves a node and nodes in the subgraph that match a set of path expressions.
