AbstractOperatingSystem

public AbstractOperatingSystem()

Method Details

getManufacturer

public java.lang.String getManufacturer()

Description copied from interface: OperatingSystem

Manufacturer.

Specified by:

getManufacturer in interface OperatingSystem

Returns:

String.

queryManufacturer

protected abstract java.lang.String queryManufacturer()

getFamily

public java.lang.String getFamily()

Description copied from interface: OperatingSystem

Operating system family.

Specified by:

getFamily in interface OperatingSystem

Returns:

String.

getVersionInfo

public OperatingSystem.OSVersionInfo getVersionInfo()

Description copied from interface: OperatingSystem

Operating system version information.

Specified by:

getVersionInfo in interface OperatingSystem

Returns:

Version information.

queryFamilyVersionInfo

protected abstract AbstractOperatingSystem.FamilyVersionInfo queryFamilyVersionInfo()

getBitness

public int getBitness()

Description copied from interface: OperatingSystem

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.

queryBitness

protected abstract int queryBitness(int jvmBitness)

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

Parameters:

jvmBitness - The bitness of the JVM

Returns:

The operating system bitness

isElevated

public boolean isElevated()

Description copied from interface: OperatingSystem

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

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

Returns:

An array of OSService objects

queryElevated

protected abstract boolean queryElevated()

processSort

protected java.util.List<OSProcess> processSort(java.util.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

getProcesses

public java.util.List<OSProcess> getProcesses()

Description copied from interface: OperatingSystem

Gets currently running processes. No order is guaranteed.

Specified by:

getProcesses in interface OperatingSystem

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.

getProcesses

public java.util.List<OSProcess> getProcesses(java.util.Collection<java.lang.Integer> pids)

Description copied from interface: OperatingSystem

Gets information on a Collection of currently running processes. This has potentially improved performance vs. iterating individual processes.

Specified by:

getProcesses in interface OperatingSystem

Parameters:

pids - A collection of process IDs

Returns:

An UnmodifiableList of OSProcess objects for the specified process ids if it is running

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
