Abstract Value Members

  1. abstract def asList(): List[Pair[String, MetadataEntry]]

    returns

    A list of (key, entry) pairs. Pairs with the same key will be ordered based on when they were added or received.

  2. abstract def asMap(): Map[String, List[MetadataEntry]]

    returns

    A map from keys to a list of metadata entries. Entries with the same key will be ordered based on when they were added or received.

  3. abstract def asScala: scaladsl.Metadata

    returns

    Returns the scaladsl.Metadata interface for this instance.

  4. abstract def getBinary(key: String): Optional[ByteString]

    returns

    The binary header value for key if one exists, if the same key has multiple values the last occurrence that is a text key is used.

  5. abstract def getText(key: String): Optional[String]

    returns

    The text header value for key if one exists, if the same key has multiple values the last occurrence that is a text key is used.
