5 years ago Thank you for asking
First there are 3 things to know
- Each bot has only a single Network Tables server
- In its simplest form a Network Tables server is a key-value database
- Where in 3.0 Flags were added to each key to enable persistence
- This library is very simple in that it is only meant to be a connection and translation layer between the server and your application
Now for how Keys work
Each Key can basically be thought of as a linux path to a file.
For example:
/SmartDashboard/Controller/MoveY
/------Table-----/-SubTable-/-Variable Name
- Table in this example is assigned by the SmartDashboard class when it calls the NetworkTable class
- SubTable is assigned by the programmer when they are adding an object to SmartDashboard
- Variable Name is basically what the programmer or the object assigned to the variable
In addition there is also a special Variable Name ~type~ which the dashboard utilizes to specify how the SubTables are shown.
Hello, I'm trying to incorporate the use of this library into one of my project and there is one thing that I don't understand - how do I connect to a specific NetworkTable? In my team's code we use a number of different tables (ImageProcessing, Preferences Etc) and I need to connect to different tables depending on the situations.
Thank you for your time
