Method Detail

open

public void open()
          throws TcTddlException

This method opens the TPM device. IBM's implementation always closes the connection after each command, so this opens and closes an empty session to test if the server can be reached.

Specified by:

open in class TcTddl

Throws:

TcTddlException - This exception is thrown if no TPM device could not be opened.

isOpen

public boolean isOpen()

This method returns true if the TPM device is already open, false otherwise.

Specified by:

isOpen in class TcTddl

close

public void close()
           throws TcTddlException

This method closes the previously opened TPM device.

Specified by:

close in class TcTddl

Throws:

TcTddlException

transmitData

public TcBlobData transmitData(TcBlobData command)
                        throws TcTddlException

This sends the given byte blob to the TPM. IBM's implementation alway closes the connection after each command, so we need to open a new one for each transmission.

Parameters:

command - The command blob to the sent to the TPM.

Throws:

TcTddlException - This exception is thrown if writing to or reading from the TPM device failed.

cancel

public void cancel()
            throws TcTddlException

This method is not implemented by this TDDL.

Specified by:

cancel in class TcTddl

Throws:

TcTddlException

getCapability

public void getCapability()
                   throws TcTddlException

This method is not implemented by this TDDL.

Specified by:

getCapability in class TcTddl

Throws:

TcTddlException

setCapability

public void setCapability()
                   throws TcTddlException

This method is not implemented by this TDDL.

Specified by:

setCapability in class TcTddl

Throws:

TcTddlException

getStatus

public void getStatus()
               throws TcTddlException

This method is not implemented by this TDDL.

Specified by:

getStatus in class TcTddl

Throws:

TcTddlException

setStatus

public void setStatus()
               throws TcTddlException

This method is not implemented by this TDDL.

Specified by:

setStatus in class TcTddl

Throws:

TcTddlException

powerManagement

public void powerManagement()
                     throws TcTddlException

This method is not implemented by this TDDL.

Specified by:

powerManagement in class TcTddl

Throws:

TcTddlException

powerManagementControl

public void powerManagementControl()
                            throws TcTddlException

This method is not implemented by this TDDL.

Specified by:

powerManagementControl in class TcTddl

Throws:

TcTddlException
