          public MetaDataService(MetaDataService delegate)

    - #### MetaDataService

          public MetaDataService(Object delegate)

  - ### Method Detail

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Object`

    - #### equals

          public boolean equals(Object o)

      Overrides:
        `equals` in class `Object`

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `Object`

    - #### getDelegate

          public MetaDataService getDelegate()

    - #### fetchTOC

          public Single<Boolean> fetchTOC(String url)

      Fetches the FIDO2 TOC for the given URL and process the entries to the metadata store. Only valid entries will be stored. The operation will return `true` only if all entries have been added. `false` if they have been processed but at least one was invalid. The operation will only fail on network problems.
      Parameters:
        `url` - the url to the TOC
      Returns:
        fluent self

    - #### rxFetchTOC

          public Single<Boolean> rxFetchTOC(String url)

      Fetches the FIDO2 TOC for the given URL and process the entries to the metadata store. Only valid entries will be stored. The operation will return `true` only if all entries have been added. `false` if they have been processed but at least one was invalid. The operation will only fail on network problems.
      Parameters:
        `url` - the url to the TOC
      Returns:
        fluent self

    - #### addStatement

          public MetaDataService addStatement(JsonObject statement)

      Manually feed a Meta Data Statement to the service.
      Parameters:
        `statement` - the json statement
      Returns:
        fluent self

    - #### flush

          public MetaDataService flush()

      Clears all loaded statements, both from the TOC and manually inserted. The flush operation will not cancel any in-flight TOC download/processing.
      Returns:
        fluent self

    - #### verify

          public JsonObject verify(Authenticator authenticator)

      Verify the metadata for a given authenticator. The MDS will lookup the metadata by the AAGUID. If no AAGUID is known, the result will be `null`. When a statement is found, the statement will be used to verify the certificate chain. A failure during this verification will throw a `RuntimeException`.
      Parameters:
        `authenticator` - authenticator to verify
      Returns:
        an MDS statement for this authenticator or `null`.

    - #### newInstance

          public static MetaDataService newInstance(MetaDataService arg)
