Method Details
- isSupported
  
  public static boolean isSupported()
  
  Checks if the Pcap subclass at a specific libpcap API version is natively supported. This is a safe method to use anytime on any platform, weather native library is present or not.
  For example, Pcap1_0.isSupported() will accurately ascertain if libpcap API version 1.0 level calls are supported by the system runtime. Also a call such as WinPcap.isSupported() will determine if WinPcap related calls, ie. native WinPcap 4.1.3 or less, are supported and by extension if this is a Microsoft Windows platform.
  
  Due to libpcap API versioning, it is safe to assume that if Pcap1_10.isSupported() returns true, that at least libpcap API version 1.0 is installed on this platform, and that all lower version calls such as libpcap 0.8 and 0.9 are available as well. The subclass hierarchy of jNetPcap module reflects the versioning of libpcap and its derivatives and the public releases of the native libraries. For example Npcap class extends WinPcap class because Npcap project took over the support for WinPcap where it left off.
  
  Implementation notes: The check is performed by verifying that certain, subclass specific native symbols were linked with Pcap full which was introduced at a specific libpcap or related API levels.
  
  Returns:
  
  true, if pcap is supported up to this specific version level, otherwise false
