Building Delphi Classes from JSON

JSON to Delphi Classes

I’m currently working on a new blog post showing how to integrate a popular REST API. One of my tasks is to convert JSON to Delphi Objects, so I need to define the Delphi class structures to work with so I can use the TJSON.JSONToObject that I covered previously. I decided to see if anyone had done work to convert JSON into Delphi classes.

Thankfully YES! I found this really handy project JsonToDelphiClass on GitHUB by . The project in covered in the post Introducing JsonToDelphiClass.

The JSON to Delphi Project is a Delphi FMX application that has a simple UI that allows you to modify the automatically created JSON class names which is pretty useful and the code worked first time when copied into my sample. (although I have more playing to do)

The JSON to Delphi tool is definitely a useful resource to work alongside the REST Debugger that you can find in the BIN directory of your RAD Studio install.

Stay tuned for the blog post when it arrives, but in the mean time, if your working with the REST components, I would recommend checking out Petar’s project along side my earlier post on Integrating Microsoft Azure Translation Services into Delphi.

Delphi 64bit Code

Updating 32bit code to Delphi 64bit

Ever since Delphi XE2, it has been possible to generate Delphi 64bit applications from the same code base as your traditional Windows 32bit Delphi code. The business case for 64-bit for business is covered in this tech paper The Impact of 64-bit Applications to your Company’s Bottom Line.

On the whole moving to 64bit (on iOS or Windows) is beautifully simple to achieve! It can be just as simple as adding the Delphi 64bit Windows target platform in the project manager and rebuilding the project.

My experience from talking to many developers who have moved up is that normally there are a few things to check in your code but typically its not a massive task to get compiling and ready to test.

A lot has been recorded on moving from Windows 32bit to Windows 64bit Delphi and this should be a useful summary if your just planning now moving up from older versions of Delphi to Delphi 10. If you are building iOS applications, then you will need to use the 64bit build now to get into the AppStore. Thankfully, Delphi has made the task of using 64bit very simple across all platforms and protected us from the headaches non Delphi Developers have had on the whole.

Lets start with this short video from David I who covers some the foundations in 7 minutes!

InterBase Journaling

We (geeks) should all know that applications that run in memory run faster than those that have regular disk I/O.

Having more of the data processing in memory has a positive effect on speed and performance,  however its not without risk. As memory is transient, you are always at risk of data loss if the data in memory hasn’t been saved to disk (which is where you get the disk i/o speed degradation again.

InterBase brings together the speed of in memory data processing with the security of immediate disk I/O with InterBase Journaling. The write ahead logging enables InterBase to securely log the write transactions to the journal making the best of both worlds possible.

InterBase User Security

User Security isn’t new; everyone is use to logging into the applications they use. To help developers build cross platform applications faster, InterBase has a flexible API for user security that simplifies the access to data held in InterBase regardless if your application is deployed to Windows, Mac, Linux, iOS and Android.

User Security in InterBase helps control WHO gets to see WHAT and is enhanced with a strong encryption model (which I covered in the Rising to the Data Security Challenge webinar) so lets focus on the foundations of user security in this article.

Planning your data security!
