  - getRawFields
```
protected java.util.List<byte[]> getRawFields()
```
    Description copied from class: AbstractPacket.AbstractHeader
    
    Returns a list of byte arrays which represents this header's fields. This method is called by calcLength() and buildRawData().
    
    Specified by:
    
    getRawFields in class AbstractPacket.AbstractHeader
    
    Returns:
    
    a list of byte arrays which represents this header's fields
  - length
```
public int length()
```
    Description copied from class: AbstractPacket.AbstractHeader
    
    Returns the header length in bytes. This method calls calcLength() and caches the return value when it is called for the first time, and then, this method returns the cached value from the second time.
    
    Specified by:
    
    length in interface Packet.Header
    
    Overrides:
    
    length in class AbstractPacket.AbstractHeader
    
    Returns:
    
    the length of the byte stream of the header represented by this object in bytes
  - buildString
```
protected java.lang.String buildString()
```
    Description copied from class: AbstractPacket.AbstractHeader
    
    This method builds the value toString() will return.
    
    Overrides:
    
    buildString in class AbstractPacket.AbstractHeader
    
    Returns:
    
    a string representation of this object
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Description copied from class: AbstractPacket.AbstractHeader
    
    Indicates whether some other object is "equal to" this one using return values of getRawData(). This method should be overridden so that it does more strict comparisons more efficiently.
    
    Overrides:
    
    equals in class AbstractPacket.AbstractHeader
  - calcHashCode
```
protected int calcHashCode()
```
    Description copied from class: AbstractPacket.AbstractHeader
    
    This method builds the value hashCode() will return using the byte array getRawData() returns. This method may be better to be overridden for performance reason.
    
    Overrides:
    
    calcHashCode in class AbstractPacket.AbstractHeader
    
    Returns:
    
    a calculated hash code value for the object
