Class SNIServerName

  • Direct Known Subclasses:
    SNIHostName


    public abstract class SNIServerName
    extends Object
    Instances of this class represent a server name in a Server Name Indication (SNI) extension.

    The SNI extension is a feature that extends the SSL/TLS protocols to indicate what server name the client is attempting to connect to during handshaking. See section 3, "Server Name Indication", of TLS Extensions (RFC 6066).

    SNIServerName objects are immutable. Subclasses should not provide methods that can change the state of an instance once it has been created.

    Since:
    1.8

      Constructors 
      Modifier Constructor and Description
      protected SNIServerName(int type, byte[] encoded)
      Creates an SNIServerName using the specified name type and encoded value.
    • Constructor Detail

      • SNIServerName

        protected SNIServerName(int type,
                                byte[] encoded)
        Creates an SNIServerName using the specified name type and encoded value.

        Note that the encoded byte array is cloned to protect against subsequent modification.

        Parameters:
        type - the type of the server name
        encoded - the encoded value of the server name
        Throws:
        IllegalArgumentException - if type is not in the range of 0 to 255, inclusive.
        NullPointerException - if encoded is null
    • Method Detail

      • getType

        public final int getType()
        Returns the name type of this server name.
        Returns:
        the name type of this server name
      • getEncoded

        public final byte[] getEncoded()
        Returns a copy of the encoded server name value of this server name.
        Returns:
        a copy of the encoded server name value of this server name
      • equals

        public boolean equals(Object other)
        Indicates whether some other object is "equal to" this server name.
        Overrides:
        equals in class Object
        Parameters:
        other - the reference object with which to compare.
        Returns:
        true if, and only if, other is of the same class of this object, and has the same name type and encoded value as this server name.
        See Also:
        Object.hashCode(), HashMap
      • toString

        public String toString()
        Returns a string representation of this server name, including the server name type and the encoded server name value in this SNIServerName object.

        The exact details of the representation are unspecified and subject to change, but the following may be regarded as typical:

             "type= <name type>, value= <name value>"
         

        In this class, the format of "<name type>" is "[LITERAL] (INTEGER)", where the optional "LITERAL" is the literal name, and INTEGER is the integer value of the name type. The format of "<name value>" is "XX:...:XX", where "XX" is the hexadecimal digit representation of a byte value. For example, a returned value of an pseudo server name may look like:

             "type=(31), value=77:77:77:2E:65:78:61:6D:70:6C:65:2E:63:6E"
         
        or
             "type=host_name (0), value=77:77:77:2E:65:78:61:6D:70:6C:65:2E:63:6E"
         

        Please NOTE that the exact details of the representation are unspecified and subject to change, and subclasses may override the method with their own formats.

        Overrides:
        toString in class Object
        Returns:
        a string representation of this server name
