      public MD5Template(Object key, Object value)
      Constructs a template that matches entries whose serialized form digests to value.
      Parameters:
      key - entry key
      value - reference value to digest

    • MD5Template

      public MD5Template(Object key, byte[] digest)
      Constructs a template directly from a precomputed digest.
      Parameters:
      key - entry key
      digest - precomputed MD5 digest

      Returns the key this template is registered under.
      Specified by:
      getKey in interface Template
      Returns:
      the entry key

    • getDigest

      public byte[] getDigest()
      Returns the digest used for comparison.
      Returns:
      the MD5 digest bytes

    • getDigestAsString

      public String getDigestAsString()
      Returns the digest as a hex-encoded string.
      Returns:
      the digest hex string

    • toString

    • serialize

      public static byte[] serialize(Object obj) throws IOException
      Serializes obj via ObjectOutputStream, returning the resulting bytes.
      Parameters:
      obj - object to serialize
      Returns:
      the serialized byte array
      Throws:
      IOException - if writing fails
