Constructor Detail

AbstractOperatingSystem

public AbstractOperatingSystem()

Method Detail

getVersion

public OperatingSystemVersion getVersion()

Operating system version.

Specified by:

getVersion in interface OperatingSystem

Returns:

Version.

getFamily

public String getFamily()

Operating system family.

Specified by:

getFamily in interface OperatingSystem

Returns:

String.

getManufacturer

public String getManufacturer()

Manufacturer.

Specified by:

getManufacturer in interface OperatingSystem

Returns:

String.

processSort

protected List<OSProcess> processSort(List<OSProcess> processes,
                                      int limit,
                                      OperatingSystem.ProcessSort sort)

Sorts an array of processes using the specified sorting, returning an array with the top limit results if positive.

Parameters:

processes - The array to sort

limit - The number of results to return if positive; if zero returns all results

sort - The sorting to use, or null

Returns:

An array of size limit (if positive) or of all processes, sorted as specified

toString

public String toString()

Overrides:

toString in class 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.

Specified by:

getProcesses in interface OperatingSystem

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. Some fields that are slow to retrieve (e.g., group information on Windows, open files on Unix and Linux) will be skipped.

getProcesses

public List<OSProcess> getProcesses(Collection<Integer> pids)

Gets information on a currently running processes. This has improved performance on Windows based operating systems vs. iterating individual processes.

Specified by:

getProcesses in interface OperatingSystem

Parameters:

pids - A collection of process IDs

Returns:

An OSProcess object for the specified process ids if it is running

getBitness

public int getBitness()

Gets the bitness (32 or 64) of the operating system.

Specified by:

getBitness in interface OperatingSystem

Returns:

The number of bits supported by the operating system.

isElevated

public boolean isElevated()

Determine whether the current process has elevated permissions such as sudo / Administrator

Specified by:

isElevated in interface OperatingSystem

Returns:

True if this process has elevated permissions
