Processlauncher

Start process with Java, with more practical tools.

Usage example

See tv.hd3g.processlauncher.Exec for shortcuts examples.

Functionalities

• Create process, watches it, kill it (QUIT), check if run is correctly completed
• Catch std-out and std-err with text support, during the execution, and after.
• Can interact with process on std-in/out/err on the fly
• Provide an API for command line parameters
  • simply add new parameters
  • parse raw command line and extract parameters, manage " and space separation.
  • get parameters value
  • use simple template with command line: the command line can be configurable and code can inject variable values
• Provide an API for search and found executable file after its names, via classpath, system path, configurable paths, and adapt execnames on Windows (add extension).
• Can stop process after a max execution time
• Can be callback just after the run starts and after the running ends.
• Can just prepare and extract a Java ProcessBuilder (for an execution outside this API).
• Manage sub-process killing
• Automatically kill all running process (and sub-process) if the Java app is closing.

Test

Use maven and Junit for run internal UT and IT.

API organisation and relation

fflauncher
