示例1: shouldTraverse
import com.google.javascript.rhino.Node; //导入方法依赖的package包/类
@Override
public boolean shouldTraverse(NodeTraversal t, Node n, Node parent) {
Node gramps = n.getAncestor(2);
return gramps == null || gramps.getType() != Token.SCRIPT;
}
示例2: checkNameUsage
import com.google.javascript.rhino.Node; //导入方法依赖的package包/类
/**
* Find functions that can be inlined.
*/

// function candidate gathering.
