ACS Code Generator DLLs (Java code)
Code Generator DLLs determine what type of code is generated by ACS. From the Launch ACS/TDK dialog you select the Code Generator DLL you want to use.
ACS is supplied with the following Code Generator DLLs for generating Java code:
Java Generator Production
Use this Code Generator DLL for generating Java code for a target application.
Java Generator Animation
Use this Code Generator DLL for generating Java code that can be simulated in Modeler, that is, Modeler animates State Diagrams as the target application is running
If you have installed Modeler to the default location, the supplied Code Generator DLLs reside in subfolders of the following folder (the name of a Code Generator DLL's folder matches that of the Code Generator DLL).
For Windows 7 and later operating systems:
C:\Users\<user>\AppData\Roaming\ItsShadow\ScriptDir\JavaGen
For 64-bit versions of pre Windows 7 operating systems:
C:\Program Files (x86)\PTC Integrity Modeler\Modeler\System\JavaGen
For 32-bit versions of pre Windows 7 operating systems:
C:\Program Files\PTC Integrity Modeler\Modeler\System\JavaGen
You can customize a supplied Code Generator DLL through its associated TDK model.
