Constructor Detail

Data

public Data()

Creates a new object to encode or decode PKCS #7 Data.

Method Detail

setContent

public void setContent(byte[] octetString,
                       int offset,
                       int len)
                throws PKCS7Exception

Sets the content in this Data object.

Parameters

	octetString		A byte array that contains arbitrary OctetString.
	offset		The offset into the OctetString array.
	len		The length of this OctetString

Throws

PKCS7Exception - If octetString is null.

getData

public byte[] getData()

Gets the content in this Data object.

Returns

A new byte array that contains arbitrary data.

getUnprocessedDataLen

public int getUnprocessedDataLen()

Returns the number of bytes in the internal buffer that contains the unprocessed data.

Overrides

getUnprocessedDataLen in class ContentInfo

Returns

The number of bytes of unprocessed data.

equals

public boolean equals(Object obj)

Returns true if this object and obj contain the same Data; returns false otherwise.

Overrides

equals in class Object

Parameters

obj

An instance of the Data class.

Returns

A boolean indicating whether these objects are equal.

clone

public Object clone()
             throws CloneNotSupportedException

Overrides the default clone method to get a deeper clone..

Overrides

clone in class ContentInfo

Returns

A copy of this object in its current state.

Throws

CloneNotSupportedException - If the cloning operation is not successful.

clearSensitiveData

public void clearSensitiveData()

Clears any sensitive data. The finalizer will clear the data, but it is not known when the garbage collector will call the finalizer. This method clears all sensitive data as soon as possible.

Overrides

clearSensitiveData in class ContentInfo
