      • getComputerSystem

        ComputerSystem getComputerSystem()
        Instantiates a ComputerSystem object. This represents the physical hardware, including components such as BIOS/Firmware and a motherboard, logic board, etc.
        Returns:
        a ComputerSystem object.
      • getPowerSources

        java.util.List<PowerSource> getPowerSources()
        Instantiates a list of PowerSource objects, representing batteries, etc.
        Returns:
        A list of PowerSource objects or an empty list if none are present.
      • getDiskStores

        java.util.List<HWDiskStore> getDiskStores()
        Instantiates a list of HWDiskStore objects, representing physical hard disks or other similar storage devices.
        Returns:
        A list of HWDiskStore objects or an empty list if none are present.
      • getLogicalVolumeGroups

        default java.util.List<LogicalVolumeGroup> getLogicalVolumeGroups()
        Instantiates a list of LogicalVolumeGroup objects, representing a storage pool or group of devices, partitions, volumes, or other implementation specific means of file storage.

        If not yet implemented or if logical volume groups do not exist, returns an empty list.

        Currently implemented for Linux (LVM2), macOS (Core Storage), and Windows (Storage Spaces).

        Returns:
        A list of LogicalVolumeGroup objects or an empty list if none are present.
      • getNetworkIFs

        java.util.List<NetworkIF> getNetworkIFs()
        Gets a list of non-local NetworkIF objects, representing a network interface. The list excludes local interfaces.
        Returns:
        A list of NetworkIF objects representing the interfaces
      • getNetworkIFs

        java.util.List<NetworkIF> getNetworkIFs​(boolean includeLocalInterfaces)
        Gets a list NetworkIF objects, representing a network interface.
        Parameters:
        includeLocalInterfaces - whether to include local interfaces (loopback or no hardware address) in the result
        Returns:
        A list of NetworkIF objects representing the interfaces
      • getDisplays

        java.util.List<Display> getDisplays()
        Instantiates a list of Display objects, representing monitors or other video output devices.
        Returns:
        A list of Display objects or an empty list if none are present.
      • getSensors

        Sensors getSensors()
        Instantiates a Sensors object, representing CPU temperature and fan speed.
        Returns:
        A Sensors object
      • getUsbDevices

        java.util.List<UsbDevice> getUsbDevices​(boolean tree)
        Instantiates a list of UsbDevice objects, representing devices connected via a usb port (including internal devices).

        If the value of tree is true, the top level devices returned from this method are the USB Controllers; connected hubs and devices in its device tree share that controller's bandwidth. If the value of tree is false, USB devices (not controllers) are listed in a single flat list.

        Parameters:
        tree - If true, returns devices connected to the existing device, accessible via UsbDevice.getConnectedDevices(). If false returns devices as a flat list with no connected device information.
        Returns:
        A list of UsbDevice objects representing (optionally) the USB Controllers and devices connected to them, or an empty list if none are present
      • getSoundCards

        java.util.List<SoundCard> getSoundCards()
        Instantiates a list of SoundCard objects, representing the Sound cards.
        Returns:
        A list of SoundCard objects or an empty list if none are present.
      • getGraphicsCards

        java.util.List<GraphicsCard> getGraphicsCards()
        Instantiates a list of GraphicsCard objects, representing the Graphics cards.
        Returns:
        A list of objects or an empty list if none are present.
