    Generate the Java source code to process the rows from child SparkPlan.

    This should be override by subclass to support codegen.

    For example, Filter will generate the code like this:

    # code to evaluate the predicate expression, result is isNull1 and value2 if (isNull1 || !value2) continue; # call consume(), which will call parent.doConsume()

    Note: A plan can either consume the rows as UnsafeRow (row), or a list of variables (input).

    Overridden by concrete implementations of SparkPlan. It is guaranteed to run before any execute of SparkPlan. This is helpful if we want to set up some state before executing the query, e.g., BroadcastHashJoin uses it to broadcast asynchronously.

    Note: the prepare method has already walked down the tree, so the implementation doesn't need to call children's prepare methods.
