--------------------------------------
Summary: Add appropriate constant flag on UDF inputs that are used
in the setup method
Key: DRILL-2360
URL: https://issues.apache.org/jira/browse/DRILL-2360
Project: Apache Drill
Issue Type: Bug
Components: Functions - Drill
Reporter: Jason Altekruse
Assignee: Daniel Barclay (Drill)
A number of UDFs do not include the appropriate flag to declare them as
constants when the should be. Any input used in the setup method should include
a constant flag in the @Param annotation for it (this allows us to detect and
throw a helpful error message if they are used incorrectly). A correct example
can be found in StringFunctions.RegexpReplace, an incorrect example can be
found in GFloat8ToChar (available after running the freemarker generation that
is a part of the default mvn install build).
