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.

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.
type
- the type of the server nameencoded
- the encoded value of the server nameIllegalArgumentException

is not in the range of 0 to 255, inclusive.NullPointerException
- if encoded
is nullpublic final int getType()
Returns the name type of this server name.
public final byte[] getEncoded()
Returns a copy of the encoded server name value of this server name.
public boolean equals(Object other)
Indicates whether some other object is "equal to" this server name.
equals
in class Object
other
- the reference object with which to compare.other
is of the same class of this object, and has the same name type and encoded value as this server name.Object.hashCode()

public int hashCode()
Returns a hash code value for this server name.
The hash code value is generated using the name type and encoded value of this server name.

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.
