a reference to this object.

bigIntValue

public ByteArrayAttribute bigIntValue(BigInteger value)

Set the big integer value whose unsigned byte-array representation is the content 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.

Returns:

a reference to this object.

getValue

public byte[] getValue()

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

Specified by:

getValue in class Attribute

Returns:

The byte-array value of this attribute or null.
