Constructor Detail

ByteArrayAttribute

public ByteArrayAttribute(java.lang.Long type)

Constructor taking the PKCS#11 type of the attribute.

Parameters:

type - The PKCS'11 type of this attribute; e.g. PKCS11Constants.CKA_VALUE.

Preconditions:

(type != null)

Method Detail

setByteArrayValue

public void setByteArrayValue(byte[] value)

Set the byte-array value of this attribute. Null, is also valid. A call to this method sets the present flag to true.

Parameters:

value - The byte-array value to set. May be null.

getByteArrayValue

public byte[] getByteArrayValue()

Get the byte-array value of this attribute. Null, is also possible.

Returns:

The byte-array value of this attribute or null.

getValueString

protected java.lang.String getValueString()

Get a string representation of the value of this attribute.

Overrides:

getValueString in class Attribute

Returns:

A string representation of the value of this attribute.

Postconditions:

(result != null)

equalsValue

protected boolean equalsValue(java.lang.Object otherObject)

Description copied from class: Attribute

True, if both attribute values are null or if both attribute values are equal. False, otherwise.

Overrides:

equalsValue in class Attribute

Parameters:

otherObject - The other object to compare to.

Returns:

True, if both attribute values are null or if both attribute values are equal. False, otherwise.

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 Attribute

Returns:

The hash code of this object.

setValue

public void setValue(java.lang.Object value)
              throws java.lang.UnsupportedOperationException

Description copied from class: Attribute

Redirects the request for setting the attribute value to the implementing attribute class.

Specified by:

setValue in class Attribute

Parameters:

value - the new value

Throws:

java.lang.UnsupportedOperationException - the OtherAttribute implementation does not support setting a value directly.
