Method Detail

### fillFields

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

  Description copied from class: `EscherRecord`
  The contract of this method is to deserialize an escher record including it's children.

  Specified by:
    `fillFields` in class `EscherRecord`
  Parameters:
    `data` - The byte array containing the serialized escher records.
    `offset` - The offset into the byte array.
    `recordFactory` - A factory for creating new escher records.
  Returns:
    The number of bytes written.

### serialize

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

  Description copied from class: `EscherRecord`
  Serializes the record to an existing 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.

### 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

### getRecordId

    public short getRecordId()

  Description copied from class: `EscherRecord`
  Return the current record id.

  Overrides:
    `getRecordId` in class `EscherRecord`
  Returns:
    The 16 bit record id.

### getRecordName

    public java.lang.String getRecordName()

  Description copied from class: `EscherRecord`
  Subclasses should return the short name for this escher record.

  Specified by:
    `getRecordName` in class `EscherRecord`

### toString

    public java.lang.String toString()

  Returns the string representation of this record.

  Overrides:
    `toString` in class `java.lang.Object`

### getNumShapes

    public int getNumShapes()

  The number of shapes in this drawing group.

### setNumShapes

    public void setNumShapes(int field_1_numShapes)

  The number of shapes in this drawing group.

### getLastMSOSPID

    public int getLastMSOSPID()

  The last shape id used in this drawing group.

### setLastMSOSPID

    public void setLastMSOSPID(int field_2_lastMSOSPID)

  The last shape id used in this drawing group.

### getDrawingGroupId

    public short getDrawingGroupId()

  Gets the drawing group id for this record. This is encoded in the instance part of the option record.

  Returns:
    a drawing group id.

### incrementShapeCount

    public void incrementShapeCount()
