> Support Code Generation for RexNode
> -----------------------------------
>
> Key: FLINK-11788
> URL: https://issues.apache.org/jira/browse/FLINK-11788
> Project: Flink
> Issue Type: New Feature
> Components: SQL / Planner
> Reporter: Jark Wu
> Assignee: Jark Wu
> Priority: Major
>
> Introduce {{CodeGeneratorContext}} and {{ExprCodeGenerator}} to support
> generation codes from RexNode.
> The {{CodeGeneratorContext}} will keep all the reusable statements which will
> be the basic class for code generation. In the future, we will introduce
> {{FunctionCodeGeneration}}, {{AggregateCodeGeneration}}, etc... and they will
> depend on the {{CodeGeneratorContext}} to store reusable statements.
> The {{ExprCodeGenerator}} will only do generating codes from RexNode.
