Method Detail

getFileSystem

public FileSystem getFileSystem()

Instantiates a FileSystem object.

Returns:

A FileSystem object.

getProcesses

public OSProcess[] getProcesses(int limit,
                                OperatingSystem.ProcessSort sort)

Gets currently running processes. If a positive limit is specified, returns only that number of processes; zero will return all processes. The order may be specified by the sort parameter, for example, to return the top cpu or memory consuming processes; if null, no order is guaranteed.

Parameters:

limit - Max number of results to return, or 0 to return all results

sort - If not null, determines sorting of results

Returns:

An array of OSProcess objects for the specified number (or all) of currently running processes, sorted as specified. The array may contain null elements if a process terminates during iteration.

getProcess

public OSProcess getProcess(int pid)

Gets information on a currently running process

Parameters:

pid - A process ID

Returns:

An OSProcess object for the specified process id if it is running; null otherwise

getChildProcesses

public OSProcess[] getChildProcesses(int parentPid,
                                     int limit,
                                     OperatingSystem.ProcessSort sort)

Gets currently running child processes of provided PID. If a positive limit is specified, returns only that number of processes; zero will return all processes. The order may be specified by the sort parameter, for example, to return the top cpu or memory consuming processes; if null, no order is guaranteed.

Parameters:

parentPid - A process ID

limit - Max number of results to return, or 0 to return all results

sort - If not null, determines sorting of results

Returns:

An array of OSProcess objects presenting the specified number (or all) of currently running child processes of the provided PID, sorted as specified. The array may contain null elements if a process terminates during iteration.

getProcessId

public int getProcessId()

Gets the current process ID

Returns:

the Process ID of the current process

getProcessCount

public int getProcessCount()

Get the number of processes currently running

Returns:

The number of processes running

getThreadCount

public int getThreadCount()

Get the number of threads currently running

Returns:

The number of threads running

getNetworkParams

public NetworkParams getNetworkParams()

Instantiates a NetworkParams object.

Returns:

A NetworkParams object.
