public int getApplicationBufferSize()
Gets the current size of the largest application data that is
expected when using this session.

SSLEngine application data buffers must be large
enough to hold the application data from any inbound network
application data packet received.  Typically, outbound
application data buffers can be of any size.

 public String getCipherSuite()
Returns the name of the SSL cipher suite which is used for all
connections in the session.

 This defines the level of protection
provided to the data sent on the connection, including the kind
of encryption used and most aspects of how authentication is done.

 public long getCreationTime()
Returns the time at which this Session representation was created,
in milliseconds since midnight, January 1, 1970 UTC.

 public byte[] getId()
Returns the identifier assigned to this Session.

 public long getLastAccessedTime()
Returns the last time this Session representation was accessed by the
session level infrastructure, in milliseconds since
midnight, January 1, 1970 UTC.

Access indicates a new connection being established using session data.
Application level operations, such as getting or setting a value
associated with the session, are not reflected in this access time.

 This information is particularly useful in session management
policies.  For example, a session manager thread could leave all
sessions in a given context which haven't been used in a long time;
or, the sessions might be sorted according to age to optimize some task.

 public Certificate[] getLocalCertificates()
Returns the certificate(s) that were sent to the peer during
handshaking.

Note: This method is useful only when using certificate-based
cipher suites.

When multiple certificates are available for use in a
handshake, the implementation chooses what it considers the
"best" certificate chain available, and transmits that to
the other side.  This method allows the caller to know
which certificate chain was actually used.

 public Principal getLocalPrincipal()
Returns the principal that was sent to the peer during handshaking.

 public int getPacketBufferSize()
Gets the current size of the largest SSL/TLS packet that is expected
when using this session.

A SSLEngine using this session may generate SSL/TLS
packets of any size up to and including the value returned by this
method. All SSLEngine network buffers should be sized
at least this large to avoid insufficient space problems when
performing wrap and unwrap calls.

 public X509Certificate[] getPeerCertificateChain() throws SSLPeerUnverifiedException
Returns the identity of the peer which was identified as part
of defining the session.

Note: This method can be used only when using certificate-based
cipher suites; using it with non-certificate-based cipher suites,
such as Kerberos, will throw an SSLPeerUnverifiedException.

Note: this method exists for compatibility with previous
releases. New applications should use
#getPeerCertificates  instead.

 public Certificate[] getPeerCertificates() throws SSLPeerUnverifiedException
Returns the identity of the peer which was established as part
of defining the session.

Note: This method can be used only when using certificate-based
cipher suites; using it with non-certificate-based cipher suites,
such as Kerberos, will throw an SSLPeerUnverifiedException.

 public String getPeerHost()
Returns the host name of the peer in this session.

For the server, this is the client's host;  and for
the client, it is the server's host. The name may not be
a fully qualified host name or even a host name at all as
it may represent a string encoding of the peer's network address.
If such a name is desired, it might
be resolved through a name service based on the value returned
by this method.

This value is not authenticated and should not be relied upon.
It is mainly used as a hint for SSLSession caching
strategies.

 public int getPeerPort()
Returns the port number of the peer in this session.

For the server, this is the client's port number;  and for
the client, it is the server's port number.

This value is not authenticated and should not be relied upon.
It is mainly used as a hint for SSLSession caching
strategies.

 public Principal getPeerPrincipal() throws SSLPeerUnverifiedException
Returns the identity of the peer which was established as part of
defining the session.

 public String getProtocol()
Returns the standard name of the protocol used for all
connections in the session.

 This defines the protocol used in the connection.

 public SSLSessionContext getSessionContext()
Returns the context in which this session is bound.

This context may be unavailable in some environments,
in which case this method returns null.

If the context is available and there is a
security manager installed, the caller may require
permission to access it or a security exception may be thrown.
In a Java environment, the security manager's
checkPermission method is called with a
SSLPermission("getSSLSessionContext") permission.

 public Object getValue(String name)
Returns the object bound to the given name in the session's
application layer data.  Returns null if there is no such binding.

For security reasons, the same named values may not be
visible across different access control contexts.

 public String[] getValueNames()
Returns an array of the names of all the application layer
data objects bound into the Session.

For security reasons, the same named values may not be
visible across different access control contexts.

 public  void invalidate()
Invalidates the session.

Future connections will not be able to
resume or join this session.  However, any existing connection
using this session can continue to use the session until the
connection is closed.

 public boolean isValid()
Returns whether this session is valid and available for resuming or
joining.

 public  void putValue(String name,
    Object value)
Binds the specified value object into the
session's application layer data
with the given name.

Any existing binding using the same name is
replaced.  If the new (or existing) value implements the
SSLSessionBindingListener interface, the object
represented by value is notified appropriately.

For security reasons, the same named values may not be
visible across different access control contexts.

 public  void removeValue(String name)
Removes the object bound to the given name in the session's
application layer data.  Does nothing if there is no object
bound to the given name.  If the bound existing object
implements the SessionBindingListener interface,
it is notified appropriately.

For security reasons, the same named values may not be
visible across different access control contexts.
