This PR move codegen implementation of expressions into Expression class itself, make it easy to manage.
It introduces two APIs in Expression:
```
def gen(ctx: CodeGenContext): GeneratedExpressionCode
def genCode(ctx: CodeGenContext, ev: GeneratedExpressionCode): Code
```
gen(ctx) will call genSource(ctx, ev) to generate Java source code for the current expression. A expression needs to override genSource().
Here are the types:
```
type Term String
type Code String
/**
* Java source for evaluating an [[Expression]] given a [[Row]] of input.
*/
case class GeneratedExpressionCode(var code: Code,
nullTerm: Term,
primitiveTerm: Term,
objectTerm: Term)
/**
* A context for codegen, which is used to bookkeeping the expressions those are not supported
* by codegen, then they are evaluated directly. The unsupported expression is appended at the
* end of `references`, the position of it is kept in the code, used to access and evaluate it.
*/
class CodeGenContext {
/**
* Holding all the expressions those do not support codegen, will be evaluated directly.
*/
val references: Seq[Expression] = new mutable.ArrayBuffer[Expression]()
}
```
This is basically apache#6660, but fixed style violation and compilation failure.
