Class MonotonicCounter

java.lang.Object

iaik.pkcs.pkcs11.objects.Object

iaik.pkcs.pkcs11.objects.HardwareFeature

iaik.pkcs.pkcs11.objects.MonotonicCounter

All Implemented Interfaces:

java.lang.Cloneable

public class MonotonicCounter
extends HardwareFeature

Objects of this class represent a monotonic counter as specified by PKCS#11 v2.11. Remind that this is a snapshot; this means that this object does not get the values from the token on demand it gets them upon instantiation.

Version:

1.0

Invariants:

(resetOnInit_ != null) and (hasReset_ != null) and (value_ != null)

Field Detail

resetOnInit_

protected BooleanAttribute resetOnInit_

Constructor Detail

MonotonicCounter

public MonotonicCounter()

Default Constructor.

MonotonicCounter

protected MonotonicCounter(Session session,
                           long objectHandle)
                    throws TokenException

Called by getInstance to create an instance of a PKCS#11 monotonic counter.

Parameters:

session - The session to use for reading attributes. This session must have the appropriate rights; i.e. it must be a user-session, if it is a private object.

objectHandle - The object handle as given from the PKCS#111 module.

Throws:

TokenException - If getting the attributes failed.

Preconditions:

(session != null)

Method Detail

getInstance

public static Object getInstance(Session session,
                                 long objectHandle)
                          throws TokenException

The getInstance method of the HardwareFeature class uses this method to create an instance of a PKCS#11 monotonic counter.

Parameters:

session - The session to use for reading attributes. This session must have the appropriate rights; i.e. it must be a user-session, if it is a private object.

objectHandle - The object handle as given from the PKCS#111 module.

Returns:

The object representing the PKCS#11 object. The returned object can be casted to the according sub-class.

Throws:

TokenException - If getting the attributes failed.

Postconditions:

(result != null)

Preconditions:

(session != null)

putAttributesInTable

protected static void putAttributesInTable(MonotonicCounter object)

Put all attributes of the given object into the attributes table of this object. This method is only static to be able to access invoke the implementation of this method for each class separately (see use in clone()).

Parameters:

object - The object to handle.

Preconditions:

(object != null)

allocateAttributes

protected void allocateAttributes()

Allocates the attribute objects for this class and adds them to the attribute table.

Overrides:

allocateAttributes in class HardwareFeature

clone

public java.lang.Object clone()

Create a (deep) clone of this object.

Overrides:

clone in class HardwareFeature

Returns:

A clone of this object.

Postconditions:

(result != null) and (result instanceof MonotonicCounter) and (result.equals(this))

equals

public boolean equals(java.lang.Object otherObject)

Compares all member variables of this object with the other object. Returns only true, if all are equal in both objects.

Overrides:

equals in class HardwareFeature

Parameters:

otherObject - The other object to compare to.

Returns:

True, if other is an instance of this class and all member variables of both objects are equal. False, otherwise.

getHasReset

public BooleanAttribute getHasReset()

Gets the has-reset attribute of this monotonic counter object.

Returns:

The has-reset attribute.

Postconditions:

(result != null)

isResetOnInit

public BooleanAttribute isResetOnInit()

Gets the reset-on-init attribute of this monotonic counter object.

Returns:

The reset-on-init attribute.

Postconditions:

(result != null)

getValue

public ByteArrayAttribute getValue()

Gets the value attribute of this monotonic counter object.

Returns:

The value attribute.

Postconditions:

(result != null)

hashCode

public int hashCode()

The overriding of this method should ensure that the objects of this class work correctly in a hashtable.

Overrides:

hashCode in class HardwareFeature

Returns:

The hash code of this object.

toString

public java.lang.String toString()

This method returns a string representation of the current object. The output is only for debugging purposes and should not be used for other purposes.

Overrides:

toString in class HardwareFeature

Returns:

A string presentation of this object for debugging output.

Postconditions:

(result != null)
