Method Summary

Method Details

• command

  Optional<String> command()

  Returns the executable pathname of the process.

  Returns:

  an Optional<String> of the executable pathname of the process

• commandLine

  Optional<String> commandLine()

  Returns the command line of the process.

  If command() and arguments() return non-empty optionals, this is simply a convenience method which concatenates the values of the two functions separated by spaces. Otherwise, it will return a best-effort, platform dependent representation of the command line.

  API Note:

  Note that the returned executable pathname and the arguments may be truncated on some platforms due to system limitations.

  The executable pathname may contain only the name of the executable without the full path information. It is undecidable whether white space separates different arguments or is part of a single argument.

  Returns:

  an Optional<String> of the command line of the process

• arguments

  Optional<String[]> arguments()

  Returns an array of Strings of the arguments of the process.

  API Note:

  On some platforms, native applications are free to change the arguments array after startup and this method may only show the changed values.

  Returns:

  an Optional<String[]> of the arguments of the process

• startInstant

  Optional<Instant> startInstant()

  Returns the start time of the process.

  Returns:

  an Optional<Instant> of the start time of the process

• totalCpuDuration

  Optional<Duration> totalCpuDuration()

  Returns the total cputime accumulated of the process.

  Returns:

  an Optional<Duration> for the accumulated total cputime

• user

  Optional<String> user()

  Return the user of the process.

  Returns:

  an Optional<String> for the user of the process
