android - Caching downloaded JSON data to SQLite database - is it a good idea? -

-

In my app I have to download the Jasonon data from many web services. The data classes I use are quite complex ( Lots of properties, deep legacy trees, etc.).

I intend to do caching using a single DB table, where I will store the downloaded JSON data in a VARCHAR column (with other meta-data columns). JSON is being done with the serialization GSN Library.

It is quite convenient to just dump the instances in JSON, and when I need them, then parses them later. There is no need to create custom tables for every category, or write down loads of custom serialization codes. Besides, I can ask questions like this on the cash table.

Question: Is this approach any kind of anti-pattern?

This approach is not completely wrong; However, I'm going to recommend that you use caching storage instead. See the section "Save cache files" for more details. In this way, you can not leave any valuable location if your JSON objects are large when your storage conditions are low

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
