Functions
ProcessHandle
Constructor function.
Syntax
var myObject = new ProcessHandle();
var myObject = new ProcessHandle(otherProcessHandle);
var myObject = new ProcessHandle(processId);
Arguments
- otherProcessHandle - (ProcessHandle) other ProcessHandle to copy
- processId - (integer) process identifier to manage
Exceptions
- (ParameterTypeError) incorrect parameter type
- (ParameterCountError) incorrect parameter count
Example
Create a ProcessHandle representing an invalid process.
var myObject = new ProcessHandle();
Create a ProcessHandle representing a copy of otherProcessHandle.
var myObject = new ProcessHandle(otherProcessHandle);
Create a ProcessHandle linked to the process id 1337.
var myObject = new ProcessHandle(1337);
Methods
clone
Returns a copy of this ProcessHandle.
Syntax
myObject.clone();
Returns
- (ProcessHandle) a copy of this ProcessHandle
Example
var copyOfMyObject = myObject.clone();
equals
Returns true if this ProcessHandle and another are referencing the same process.
Syntax
myObject.equals(other);
Arguments
- other - (ProcessHandle) another ProcessHandle
Returns
- (bool) true if other is referencing the same process
Example
if(myFirstObject.equals(mySecondObject)) //Do something
toString
Returns a string representing this ProcessHandle.
Syntax
myObject.toString();
Returns
- (string) a string representing this ProcessHandle
Example
Console.print(myObject.toString());
Notes
This method is automatically called when trying to convert a ProcessHandle to a string.
id
Returns the process id.
Syntax
myObject.id();
Returns
- (integer) the process id
kill
Try to kill the process.
Syntax
myObject.kill(killMode, timeout);
Arguments
- killMode - (KillMode) the kill mode to use
- timeout - (integer) the timeout in milliseconds to wait when using GracefulThenForceful
Returns
- (boolean) true if the process was killed
isRunning
Returns true if the process is currently running.
Syntax
myObject.isRunning();
Returns
- (boolean) true if the process is currently running
command
Returns the command that was used to start this process.
Syntax
myObject.command();
Returns
- (string) the command that was used to start this process
Exceptions
- (OpenProcessError) unable to open the process (Windows)
- (GetModuleFilenameError) unable to get the module filename (Windows)
- (GetProcessError) unable to get the process command (Linux)
priority
Returns the priority of this process.
Syntax
myObject.priority();
Returns
- (Priority) the process priority
Exceptions
- (OpenProcessError) unable to open the process (Windows)
- (GetPriorityClassError) unable to get priority class (Windows)
- (OperatingSystemError) this is not available on this operating system (Linux)
Notes
This method only works on Windows, because Linux doesn't have any concept of process priority.
Enumerations
KillMode
Policy to use when trying to kill a process.
Values
- Graceful: Linux: send a SIGTERM signal Windows: close all windows owned by this process
- Forceful: Linux: send a SIGKILL signal Windows: use TerminateProcess to kill this process
- GracefulThenForceful: try to kill the process using the graceful technique, wait for timeout and kill it using the forceful technique
Priority
A process priority.
Values
- AboveNormal: above normal
- BelowNormal: below normal
- High: high
- Idle: idle
- Normal: normal
- Realtime: realtime
