示例1: leaveBlock
import jdk.nashorn.internal.ir.ReturnNode; //导入方法依赖的package包/类
@Override
public Node leaveBlock(final Block block) {
//now we have committed the entire statement list to the block, but we need to truncate
//whatever is after the last terminal. block append won't append past it
if (lc.isFunctionBody()) {
final FunctionNode currentFunction = lc.getCurrentFunction();
final boolean isProgram = currentFunction.isProgram();
final Statement last = lc.getLastStatement();
final ReturnNode returnNode = new ReturnNode(
last == null ? currentFunction.getLineNumber() : last.getLineNumber(), //TODO?
currentFunction.getToken(),
