Method Detail

deserialize

public static <T extends AuthenticationToken> T deserialize(Class<T> tokenType,
                                                            byte[] tokenBytes)

A convenience method to create tokens from serialized bytes, created by serialize(AuthenticationToken)

The specified tokenType will be instantiated, and used to deserialize the decoded bytes. The resulting object will then be returned to the caller.

Parameters:

tokenType - the token class to use to deserialize the bytes

tokenBytes - the token-specific serialized bytes

Returns:

an AuthenticationToken instance of the type specified by tokenType

serialize(AuthenticationToken)

deserialize

public static AuthenticationToken deserialize(String tokenClassName,
                                              byte[] tokenBytes)

An alternate version of deserialize(Class, byte[]) that accepts a token class name rather than a token class.

Parameters:

tokenClassName - the fully-qualified class name to be returned

serialize(AuthenticationToken)

serialize

public static byte[] serialize(AuthenticationToken token)

A convenience method to serialize tokens.

The provided AuthenticationToken will be serialized to bytes by its own implementation and returned to the caller.

Parameters:

token - the token to serialize

Returns:

a serialized representation of the provided AuthenticationToken
