Interface ProcessHandle.Info
- Enclosing interface:
ProcessHandle
public static interface ProcessHandle.Info
Information snapshot about the process.
The attributes of a process vary by operating system and are not available
in all implementations. Information about processes is limited
by the operating system privileges of the process making the request.
The return types are
Optional<T>
allowing explicit tests
and actions if the value is available.- Since:

Method Details
-
command
-
commandLine
Returns the command line of the process.If
command()
andarguments()
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
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
