public int fillFields(byte[] data,
             int offset,
             EscherRecordFactory recordFactory)

This method deserializes the record from a byte array.

Specified by:

fillFields in class EscherRecord

Parameters:

data - The byte array containing the escher record information

offset - The starting offset into data.

serialize

public int serialize(int offset,
            byte[] data,
            EscherSerializationListener listener)

This method serializes this escher record into a byte array.

Specified by:

serialize in class EscherRecord

Parameters:

offset - The offset into data to start writing the record data to.

data - The byte array to serialize to.

listener - A listener to retrieve start and end callbacks. Use a NullEscherSerailizationListener to ignore these events.

Returns:

The number of bytes written.
