----------------------------------------
Summary: [C++] Remove IsSignedInt trait
Key: ARROW-6515
URL: https://issues.apache.org/jira/browse/ARROW-6515
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Benjamin Kietzman
Assignee: Benjamin Kietzman
{{IsSignedInt}} takes either an array or a type as a type argument, which is
surprisingly atypical for traits. Furthermore whereas {{is_signed_integer}}
returns false for date and other types which are represented by but not
identical to integers {{IsSignedInt}} returns true by checking only the
{{c_type}}, which leads to {{static_assert(IsSignedInt<HalfFloatType>::value,
"")}}. Finally the declaration of {{IsSignedInt}} is far from readable due to
nested macro usage.
