  - 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
  - calcLength
```
public int calcLength()
```
    Description copied from class: AbstractPacket.AbstractHeader
    
    This method calculates the value length() will return by adding up the lengths of byte arrays in the list getRawFields() returns.
    
    Overrides:
    
    calcLength in class AbstractPacket.AbstractHeader
    
    Returns:
    
    a calculated length
  - getHeaderName
```
protected abstract java.lang.String getHeaderName()
```
    Returns:
    
    the header name.
  - 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
  - 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
  - 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
