Class FileConsistencyEventDetector

java.lang.Object
  network.detectors.EventDetector
      network.detectors.FileConsistencyEventDetector

All Implemented Interfaces:

java.lang.Runnable, java.io.Serializable

public class FileConsistencyEventDetector

extends EventDetector

implements java.io.Serializable

This detector hashes all files in /usr/bin and recalculates the hashes periodically. If a file's hash does not match its previous hash, a FileConsistencyEvent is generated.
