abstract class PrefixMapReader[T] extends Iterator[(T, String)]

A reader of binary SiLK PrefixMap files. This is usable as an Iterator over a pair representing a key and value. Depending on the contents of the PrefixMap file, the key is either an IPBlock or a PrefixMapProtocolPortPair. The value is always a String.

Because the PrefixMap may contain different key types, the PrefixMapReader factory methods return a PrefixMapResult wrapper over PrefixMapReader.

The mapName method returns the map name that was specified in the PrefixMap file's header, if any.

Example:

  1. This example uses the single argument form of the companion object's ofInputStream() method to read the PrefixMap file "example.pmap". The code may be used outside of Hadoop when it is known that the key is an IPBlock.

    val stream = new java.io.FileInputStream("example.pmap")
val pmapresult = PrefixMapReader.ofInputStream(stream)
val pmap = pmapresult match {
  case PrefixMapResult.IPBlockPrefixMap(iter) => iter
  case _ => null
}
pmap.hasNext
val (ipblock, name) = pmap.next()
