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.
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()

This is documentation for Mothra, a collection of Scala and Spark library functions for working with Internet-related data. Some modules contain APIs of general use to Scala programmers. Some modules make those tools more useful on Spark data-processing systems.
Please see the documentation for the individual packages for more details on their use.
Scala Packages
These packages are useful in Scala code without involving Spark:
org.cert.netsa.data
This package, which is collected as the
netsa-data
library, provides types for working with various kinds of information:org.cert.netsa.data.net
- types for working with network dataorg.cert.netsa.data.time
- types for working with time dataorg.cert.netsa.data.unsigned
- types for working with unsigned integral valuesorg.cert.netsa.io.ipfix
The
netsa-io-ipfix
library provides tools for reading and writing IETF IPFIX data from various connections and files.org.cert.netsa.io.silk
To read and write CERT NetSA SiLK file formats and configuration files, use the
netsa-io-silk
library.org.cert.netsa.util
The "junk drawer" of
netsa-util
so far provides only two features: First, a method for equipping Scala scala.collection.Iterators with exception handling. And second, a way to query the versions of NetSA libraries present in a JVM at runtime.Spark Packages
These packages require the use of Apache Spark:
org.cert.netsa.mothra.datasources
Spark datasources for CERT file types. This package contains utility features which add methods to Apache Spark DataFrameReader objects, allowing IPFIX and SiLK flows to be opened using simple
spark.read...
calls.The
mothra-datasources
library contains both IPFIX and SiLK functionality, whilemothra-datasources-ipfix
andmothra-datasources-silk
contain only what's needed for the named datasource.org.cert.netsa.mothra.analysis
A grab-bag of analysis helper functions and example analyses.
org.cert.netsa.mothra.functions
This single Scala object provides Spark SQL functions for working with network data. It is the entirety of the
mothra-functions
library.
