Read the contents of the import Package

I am working on creating a computer controlled bots for a game using Java. I got a example bot program and I am understanding this currently.

I am not able to understand what does @JProp means in the code below. Can any one help me on this. Also, how do I view all the contents of the import files at the start of the program.

package com.mycompany.mavenproject1;

It seems this JProp annotation is used for introspection purposes (allowing the contents of the variable which is decorated to be easily inspected from within your IDE).

Quoting this manual:

Introspection is designed to ease the bot's parameterization. It is often needed to adjust multiple behavior parameters at runtime and you will probably end up creating your own GUI (graphical user interface) for this purpose. In introspection, you just annotate desired variables with @JProp annotation and they will be accessible via the Netbeans GUI.

Let's look how logging and introspection works in EmptyBot example. First start the bot (F6), then have a look on it's source code. In the initial section several variables annotated with the @JProp are defined.

@JProp
public String stringProp = "Hello bot example";
@JProp
public boolean boolProp = true;
@JProp
public int intProp = 2;
@JProp
public double doubleProp = 1.0;

Now expand bot's node under the UT server node (in Services tab), you will see two new nodes - Logs and Introspection. After selecting the Introspection node the annotated variables will be shown in the Properties (Ctrl + Shift + 7) window. Note that the intProp variable is being continuously updated. New values of variables can be also set in this window.
