Class TcTddl

java.lang.Object
  iaik.tc.tss.impl.java.tddl.TcTddl

All Implemented Interfaces:

TcIStreamDest

Direct Known Subclasses:

TcTddlLinux, TcTddlSocket, TcTddlVista

public abstract class TcTddl
extends java.lang.Object
implements TcIStreamDest

This class defines the interface to be implemented by the TDDL layer according to the TSS specification. The set of functions can be split into 2 parts: Those functions absolutely required if the TDDL is used by a TSS (the functions comprise open, isOpen, transmit and close) and the functions that are required if the TDDL is used as a standalone facility. These functions comprise the remaining TDDL functions specified by the TSS specification. For that reason, TDDL implementations might be limited to the aforementioned set of absolutely required functions.

Method Detail

getInstance

public static TcTddl getInstance()
                          throws TcTddlException

The TDDL layer is implemented as a Singleton. This method returns the instance of the TDDL.

Returns:

TDDL instance.

Throws:

TcTddlException - This exception is thrown if no TDDL implementation that fits the underlying operating system could be found.
