    • fillFields

      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.
      recordFactory - May be null since this is not a container record.
      Returns:
      The number of bytes read from the byte array.
    • serialize

      public int serialize(int offset, byte[] data, EscherSerializationListener listener)
      Writes this record and any contained records to the supplied byte array.
      Specified by:
      serialize in class EscherRecord
      Parameters:
      offset - the offset within the byte array
      data - the data array to serialize to
      listener - a listener for begin and end serialization events. This is useful because the serialization is hierarchical/recursive and sometimes you need to be able break into that.
      Returns:
      the number of bytes written.
    • getData

      public byte[] getData()
    • getRecordSize

      public int getRecordSize()
      Returns the number of bytes that are required to serialize this record.
      Specified by:
      getRecordSize in class EscherRecord
      Returns:
      Number of bytes
