Constructor Detail

Mechanism

public Mechanism()

The default constructor. An application use this constructor to instantiate an object that serves as a template. It may also be useful for working with vendor-defined objects.

Mechanism

protected Mechanism(Session session,
                    long objectHandle)
             throws TokenException

Constructor taking the reference to the PKCS#11 module for accessing the object's attributes, the session handle to use for reading the attribute values and the object handle.

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.

Method Detail

getInstance

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

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 - in case of error.

putAttributesInTable

protected static void putAttributesInTable(Mechanism 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 Object

clone

public java.lang.Object clone()

Create a (deep) clone of this object.

Overrides:

clone in class Object

Returns:

A clone of this object.

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 Object

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.

getMechanismType

public LongAttribute getMechanismType()

Returns:

returns the mechanism type of this mechanism 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 Object

Returns:

A string presentation of this object for debugging output.

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 Object

Returns:

The hash code of this object.
