[jira] [Created] (MATH-861) Make sure that entries of FieldVectors
cannot be null
Sébastien Brisard created MATH-861:
--------------------------------------
Summary: Make sure that entries of FieldVectors cannot be null
Key: MATH-861
URL: https://issues.apache.org/jira/browse/MATH-861
Project: Commons Math
Issue Type: Improvement
Reporter: Sébastien Brisard
Fix For: 3.2
As part of MATH-854, an extensive review of exceptions possibly thrown throughout CM is being carried out.
It turns out that in {{FieldVector}}, {{NullArgumentException}}s may occur because {{FieldElement}} throws such an exception for all elementary operation. In {{FieldVector}}, this has an impact on
* operations involving a {{FieldElement}} as an argument, eg {{mapAdd(T d)}} and the likes: for these method, the throws clause has been altered.
* operations involving a {{FieldVector}} as an argument, eg {{add(FieldVector<T> v}}. In order to avoid catching and rethrowing a {{NullArgumentException}}, all implementations of {{FieldVector}} should make sure that no vector entry can be {{null}}.
As a consequence
* the above statement must be added to the class comment of {{FieldVector}}
* all constructors, setters and the likes must explicitely check for {{null}}
