  • Method Details

    • getNetworks

      public static List<NetworkIF> getNetworks(boolean includeLocalInterfaces)
      Gets network interfaces on this machine
      Parameters:
      includeLocalInterfaces - include local interfaces in the result
      Returns:
      A list of NetworkIF objects representing the interfaces

    • getIfType

      public int getIfType()
      Description copied from interface: NetworkIF
      (Windows, macOS) The NDIS Interface Type. NDIS interface types are registered with the Internet Assigned Numbers Authority (IANA), which publishes a list of interface types periodically in the Assigned Numbers RFC, or in a derivative of it that is specific to Internet network management number assignments.

      (Linux) ARP Protocol hardware identifiers defined in include/uapi/linux/if_arp.h

      Returns:
      the ifType

    • isConnectorPresent

      public boolean isConnectorPresent()
      Description copied from interface: NetworkIF
      (Windows Vista and higher) Set if a connector is present on the network interface.

      (Linux) Indicates the current physical link state of the interface.

      Returns:
      true if there is a physical network adapter (Windows) or a connected cable (Linux), false otherwise

    • getBytesRecv

      public long getBytesRecv()
      Description copied from interface: NetworkIF

      Getter for the field bytesRecv.

      Returns:
      The Bytes Received.

      This value is set when the NetworkIF is instantiated and may not be up to date. To update this value, execute the NetworkIF.updateAttributes() method

    • getBytesSent

      public long getBytesSent()
      Description copied from interface: NetworkIF

      Getter for the field bytesSent.

      Returns:
      The Bytes Sent.

      This value is set when the NetworkIF is instantiated and may not be up to date. To update this value, execute the NetworkIF.updateAttributes() method

    • getPacketsRecv

      public long getPacketsRecv()
      Description copied from interface: NetworkIF

      Getter for the field packetsRecv.

      Returns:
      The Packets Received.

      This value is set when the NetworkIF is instantiated and may not be up to date. To update this value, execute the NetworkIF.updateAttributes() method

    • getPacketsSent

      public long getPacketsSent()
      Description copied from interface: NetworkIF

      Getter for the field packetsSent.

      Returns:
      The Packets Sent.

      This value is set when the NetworkIF is instantiated and may not be up to date. To update this value, execute the NetworkIF.updateAttributes() method

    • getInErrors

      public long getInErrors()
      Description copied from interface: NetworkIF

      Getter for the field inErrors.

      Returns:
      Input Errors.

      This value is set when the NetworkIF is instantiated and may not be up to date. To update this value, execute the NetworkIF.updateAttributes() method

    • getOutErrors

      public long getOutErrors()
      Description copied from interface: NetworkIF

      Getter for the field outErrors.

      Returns:
      The Output Errors.

      This value is set when the NetworkIF is instantiated and may not be up to date. To update this value, execute the NetworkIF.updateAttributes() method

    • getInDrops

      public long getInDrops()
      Description copied from interface: NetworkIF

      Getter for the field inDrops.

      Returns:
      Incoming/Received dropped packets. On Windows, returns discarded incoming packets.

      This value is set when the NetworkIF is instantiated and may not be up to date. To update this value, execute the NetworkIF.updateAttributes() method

    • getCollisions

      public long getCollisions()
      Description copied from interface: NetworkIF

      Getter for the field collisions.

      Returns:
      Packet collisions. On Windows, returns discarded outgoing packets.

      This value is set when the NetworkIF is instantiated and may not be up to date. To update this value, execute the NetworkIF.updateAttributes() method

    • getSpeed

      public long getSpeed()
      Description copied from interface: NetworkIF

      Getter for the field speed.

      Returns:
      The speed of the network interface in bits per second.

      This value is set when the NetworkIF is instantiated and may not be up to date. To update this value, execute the NetworkIF.updateAttributes() method

    • getTimeStamp

      public long getTimeStamp()
      Description copied from interface: NetworkIF

      Getter for the field timeStamp.

      Returns:
      Returns the timeStamp.

    • getIfAlias

      public String getIfAlias()
      Description copied from interface: NetworkIF
      The ifAlias as described in RFC 2863.

      The ifAlias object allows a network manager to give one or more interfaces their own unique names, irrespective of any interface-stack relationship. Further, the ifAlias name is non-volatile, and thus an interface must retain its assigned ifAlias value across reboots, even if an agent chooses a new ifIndex value for the interface.

      Only implemented for Windows (Vista and newer) and Linux.

      Returns:
      The ifAlias of the interface if available, otherwise the empty string.

    • getIfOperStatus

      public NetworkIF.IfOperStatus getIfOperStatus()
      Description copied from interface: NetworkIF
      The ifOperStatus as described in RFC 2863.

      Only implemented for Windows (Vista and newer) and Linux.

      Returns:
      The current operational state of the interface.

    • updateAttributes

      public boolean updateAttributes()
      Description copied from interface: NetworkIF
      Updates interface network statistics on this interface. Statistics include packets and bytes sent and received, and interface speed.
      Returns:
      true if the update was successful, false otherwise.
