[jira] Created: (MATH-461) RealVectorFormat throws ParseException
RealVectorFormat throws ParseException
--------------------------------------
Key: MATH-461
URL: https://issues.apache.org/jira/browse/MATH-461
Project: Commons Math
Issue Type: Improvement
Reporter: Gilles
Assignee: Gilles
Priority: Minor
Fix For: 3.0
The {{parseObject(String)}} method, inherited from the standard Java class {{Format}}, throws a _checked_ {{ParseException}}.
A new _runtime_ {{MathParseException}} is to be created to be thrown instead when parsing fails. However, this can cause a problem, as explained on the ML.
I propose that {{CompositeFormat}} becomes an instance variable of {{RealVectorFormat}} (instead of being a base class) to avoid that pitfall.

[jira] Updated: (MATH-461) RealVectorFormat throws ParseException
Posted by "Gilles (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/MATH-461?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gilles updated MATH-461:
------------------------
Attachment: MATH-461.diff
The {{ComplexFormat}} and {{Vector3DFormat}} classes present the same problem as {{RealVectorFormat}}.
Please have a look at the attached "diff" that shows the proposed changes. In summary: {{CompositeFormat}} becomes a utility class (with a "private" constructor). The various "...Format" classes do not inherit anymore from the "Format" Java class, which allows the removal of some methods (in particular, the one that throws {{ParseException}}).
