由 醉酒当歌 提交于 2019-12-22 06:31:02
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I have several "main" XSD documents, which import "supporting" XSD documents. These schema documents happen to be from the HR-XML 3.0 specification, in particular related to Background Screening. For the purposes of code-generation and convenient single-file schema to reference in my WSDL, I am trying to "flatten"

writing more complex json schemas that have dependencies upon other keys

由 有些话、适合烂在心里 提交于 2019-12-22 05:33:28
问题 I've been writing simple JSON schemas but I ran into an API input call that is a bit more complex. I have one restful end route that can take 3 very different types of JSON: localhost/foo can take: { "type" : "ice_cream", "cone" : "waffle" ...} or {"type" : "hot_dog", "bun" : "wheat" ...} If the "type" key contains "ice_cream", I only ever want to see the key "cone" and not the key "bun". Similiarly if "type" contains "hot_dog" I only want to see "bun" and not "cone". I know I can pattern

Spark: Programmatically creating dataframe schema in scala

由 不羁的心 提交于 2019-12-22 03:58:08
问题 I have a smallish dataset that will be the result of a Spark job. I am thinking about converting this dataset to a dataframe for convenience at the end of the job, but have struggled to correctly define the schema. The problem is the last field below ( topValues ); it is an ArrayBuffer of tuples -- keys and counts. val innerSchema = StructType( Array( StructField("value", StringType), StructField("count", LongType) ) ) val outputSchema = StructType( Array( StructField("name", StringType,

Different way of creating a Javascript Object?

由 旧时模样 提交于 2019-12-22 01:34:55
问题 I'm learning to code and I have a question about some sample code I found: var Comment = new Schema({ user:userStub, time:Date, content: {type:String, required: true, trim:true} }); From what I learned about OOP, I thought the Comment object instance of Schema would be built like this: function Schema (user, time, content){ this.user = user; this.time = time; this.content = content; }; var Comment = new Schema (userStub, time, content); Anyone know the advantage of building the Comment

custom schema to XMP metadata

由 坚强是说给别人听的谎言 提交于 2019-12-22 00:29:38
问题 I want to write custom metadata to a pdf file which are not supported by XMP standard schemas hence I wrote my own schema containing my own properties. I can successfully write these additional custom metadata to my PDF file using either PDFBox or iTextPDF library. I am however unable to read the custom metadata at client side without parsing the XMP xml. I guess there should be some API that I am not aware of for getting your custom schema back to your java class. Please help me if I am

SQL Schema to allow users add comments to various tables

由 别说谁变了你拦得住时间么 提交于 2019-12-21 19:58:26
问题 So, I'm building a website and I'm going to have standard CMS tables like Article, Blog, Poll, etc. I want to let users post comments to any of these items. So my question is, do I need to create separate comments tables for each (e.g. ArticleComment, BlogComment, PollComment), or can I just make a generic Comment table that could be used with any table? What has worked for people? Method 1: Many Comment Tables Article {ArticleID [PK], Title, FriendlyUrl} ArticleComment {ArticleCommendID [PK]
