public abstract class DebugSignature extends Object
A feature extracted from a function, with an additional description of what information is incorporated into the feature. The feature may incorporate data-flow and/or control-flow information from the function. Internally, the feature is a 32-bit hash of this information, but derived classes from this abstract class include more detailed information about how the hash was formed.

      public abstract void decode(Decoder decoder) throws DecoderException
      Decode the feature from a stream.
      Parameters:
      decoder - is the stream decoder
      Throws:
      DecoderException - for problems reading the stream

    • decodeSignatures

      public static ArrayList<DebugSignature> decodeSignatures(Decoder decoder, Function func) throws DecoderException
      Decode an array of features from the stream. Collectively, the features make up a "feature vector" for a specific function. Each feature is returned as a separate descriptive object.
      Parameters:
      decoder - is the stream decoder
      func - is the specific function whose feature vector is being decoded
      Returns:
      the array of feature objects
      Throws:
      DecoderException - for problems reading from the stream
