      • 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
      • getChildRecords

        public List getChildRecords()
        Overrides:
        getChildRecords in class EscherRecord
        Returns:
        Returns the children of this record. By default this will be an empty list. EscherCotainerRecord is the only record that may contain children.

      • setChildRecords

        public void setChildRecords​(List childRecords)
        Description copied from class: EscherRecord
        Sets the child records for this record. By default this will throw an exception as only EscherContainerRecords may have children.
        Overrides:
        setChildRecords in class EscherRecord
        Parameters:
        childRecords - Not used in base implementation.
