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}} -- This message is automatically generated by JIRA.
