Constructor Detail

ThresholdPublicKey

public ThresholdPublicKey(byte[] data,
                          int[] offset)
                   throws QSException
Method Detail

toString

public String toString()
Overrides:
toString in class Object

to_bytes

public void to_bytes(byte[] data,
                     int[] offset)
Description copied from interface: QuickSerializable
Store the object in its "on the wire" form in the byte array data, starting at index offset [0], and increment offset [0] by the number of bytes written; if data == null, increment offset [0] by the number of bytes that would have been written otherwise.
Specified by:
to_bytes in interface QuickSerializable
Following copied from interface: ostore.util.QuickSerializable
Parameters:
data - The byte array to store into, or null.
offset - A single element array whose first element is the index in data to begin writing at on function entry, and which on function exit has been incremented by the number of bytes written.

add_to_digest

public void add_to_digest(SecureHashBuffer buffer)
Description copied from interface: Digestible
Adds this object's state to the specified SecureHashBuffer using the various add methods.
Specified by:
