Constructor Details

MacOperatingSystem

public MacOperatingSystem()

Constructor for MacOperatingSystem.

Method Details

queryManufacturer

public java.lang.String queryManufacturer()

Specified by:

queryManufacturer in class AbstractOperatingSystem

queryFamilyVersionInfo

public AbstractOperatingSystem.FamilyVersionInfo queryFamilyVersionInfo()

Specified by:

queryFamilyVersionInfo in class AbstractOperatingSystem

queryBitness

protected int queryBitness(int jvmBitness)

Description copied from class: AbstractOperatingSystem

Backup OS-specific query to determine bitness if previous checks fail

Specified by:

queryBitness in class AbstractOperatingSystem

Parameters:

jvmBitness - The bitness of the JVM

Returns:

The operating system bitness

queryElevated

protected boolean queryElevated()

Specified by:

queryElevated in class AbstractOperatingSystem

getFileSystem

public FileSystem getFileSystem()

Description copied from interface: OperatingSystem

Instantiates a FileSystem object.

Returns:

A FileSystem object.

getInternetProtocolStats

public InternetProtocolStats getInternetProtocolStats()

Description copied from interface: OperatingSystem

Instantiates a InternetProtocolStats object.

Returns:

a InternetProtocolStats object.

getProcesses

public java.util.List<OSProcess> getProcesses(int limit, OperatingSystem.ProcessSort sort)

Description copied from interface: OperatingSystem

Gets currently running processes, optionally limited to the top "N" for a particular sorting order. 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 the sort is 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 UnmodifiableList of OSProcess objects for the specified number (or all) of currently running processes, sorted as specified. The list may contain null elements or processes with a state of OSProcess.State.INVALID if a process terminates during iteration.

getProcess

public OSProcess getProcess(int pid)

Description copied from interface: OperatingSystem

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 java.util.List<OSProcess> getChildProcesses(int parentPid, int limit, OperatingSystem.ProcessSort sort)

Description copied from interface: OperatingSystem

Gets currently running child processes of provided parent PID, optionally limited to the top "N" for a particular sorting order. 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 the sort is 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 UnmodifiableList of OSProcess objects representing the specified number (or all) of currently running child processes of the provided PID, sorted as specified. The list may contain null elements or processes with a state of OSProcess.State.INVALID if a process terminates during iteration.

getProcessId

public int getProcessId()

Description copied from interface: OperatingSystem

Gets the current process ID

Returns:

the Process ID of the current process

getProcessCount

public int getProcessCount()

Description copied from interface: OperatingSystem

Get the number of processes currently running

Returns:

The number of processes running

getThreadCount

public int getThreadCount()

Description copied from interface: OperatingSystem

Get the number of threads currently running

Returns:

The number of threads running

getSystemUptime

public long getSystemUptime()

Description copied from interface: OperatingSystem

Get the System up time (time since boot).

Returns:

Number of seconds since boot.

getSystemBootTime

public long getSystemBootTime()

Description copied from interface: OperatingSystem

Get Unix time of boot.

Returns:

The approximate time at which the system booted, in seconds since the Unix epoch.

getNetworkParams

public NetworkParams getNetworkParams()

Description copied from interface: OperatingSystem

Instantiates a NetworkParams object.

Returns:

A NetworkParams object.

getServices

public OSService[] getServices()

Description copied from interface: OperatingSystem

Gets the all services on the system. The definition of what is a service is platform-dependent.

Specified by:

getServices in interface OperatingSystem

Overrides:

getServices in class AbstractOperatingSystem

Returns:

An array of OSService objects
