- Method Detail
  - getHeader
```
public abstract AbstractPppPacket.AbstractPppHeader getHeader()
```
    Description copied from class: AbstractPacket
    
    Returns the Header object representing this packet's header. This subclass have to override this method if the packet represented by the subclass has a header.
    
    Specified by:
    
    getHeader in interface Packet
    
    Overrides:
    
    getHeader in class AbstractPacket
    
    Returns:
    
    the Header object representing this packet's header. May be null if the header doesn't exist
  - getPayload
```
public Packet getPayload()
```
    Description copied from class: AbstractPacket
    
    Returns the Packet object representing this packet's payload. This subclass have to override this method if the packet represented by the subclass has a payload.
    
    Specified by:
    
    getPayload in interface Packet
    
    Overrides:
    
    getPayload in class AbstractPacket
    
    Returns:
    
    the Packet object representing this packet's payload. May be null if the payload doesn't exist
  - getPad
```
public byte[] getPad()
```
    Returns:
    
    pad
  - calcLength
```
protected int calcLength()
```
    Description copied from class: AbstractPacket
    
    This method calculates the value length() will return by adding up the header length and the payload length. If you write this subclass which represents a packet with extra parts (e.g. a trailer), you need to override this method.
    
    Overrides:
    
    calcLength in class AbstractPacket
    
    Returns:
    
    a calculated length
  - buildRawData
```
protected byte[] buildRawData()
```
    Description copied from class: AbstractPacket
    
    This method builds the value getRawData() will return by concatenating the header's raw data and the payload's raw data. If you write this subclass which represents a packet with extra parts (e.g. a trailer), you need to override this method.
    
    Overrides:
    
    buildRawData in class AbstractPacket
    
    Returns:
    
    a raw data built
  - buildString
```
protected java.lang.String buildString()
```
    Description copied from class: AbstractPacket
    
    This method builds the value toString() will return by concatenating the header's string representation and the payload's string representation. If you write this subclass which represents a packet with extra parts (e.g. a trailer), you need to override this method.
    
    Overrides:
    
    buildString in class AbstractPacket
    
    Returns:
    
    a string representation of this object
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Description copied from class: AbstractPacket
    
    Indicates whether some other object is "equal to" this one. This method firstly compares this packet's header using the header's equals(Object) method, then compares this packet's payload using the payload's equals(Object) method. If you write this subclass with fields which represent somethings other than header or payload, you need to override this method.
    
    Overrides:
    
    equals in class AbstractPacket
  - calcHashCode
```
protected int calcHashCode()
```
    Description copied from class: AbstractPacket
    
    This method calculates the value hashCode() will return using the header's hash code and the payload's hash code. If you write this subclass which represents a packet with extra parts (e.g. a trailer), you need to override this method.
    
    Overrides:
    
    calcHashCode in class AbstractPacket
    
    Returns:
    
    a calculated hash code value for the object
