  - ### Method Detail

    - #### generateDigest

          public java.lang.String generateDigest(java.net.URL url)

      Description copied from interface: `ResourceDigestGenerator`
      Reads the content of a URL (presumably, for a resource on the classpath) and generates a digest of its content. This digest will be incorporated into the URL provided to the client, to verify that the client has been "granted" access to this resource. This is only used for resources where `ResourceDigestGenerator.requiresDigest(String)` is true. As of Tapestry 5.4, simply returns null.
      Specified by:
        `generateDigest` in interface `ResourceDigestGenerator`
      Returns:
        the digest for the resource

    - #### requiresDigest

          public boolean requiresDigest(java.lang.String path)

      Description copied from interface: `ResourceDigestGenerator`
      Examines the path (typically, the file name extension at the end of the path) to determine if a checksum is required for the path. The path is `Resource` style, without a leading slash. As of Tapestry 5.4, simply returns false.
      Specified by:
        `requiresDigest` in interface `ResourceDigestGenerator`
