    • Method Detail

      • newPacket

        public static EncryptedPacket newPacket​(byte[] rawData,
                                        int offset,
                                        int length)
        A static factory method. This method validates the arguments by ByteArrays.validateBounds(byte[], int, int), which may throw exceptions undocumented here.
        Parameters:
        rawData - rawData
        offset - offset
        length - length
        Returns:
        a new EncryptedPacket object.

      • getBuilder

        public EncryptedPacket.Builder getBuilder()
        Description copied from interface: Packet
        Returns a new Builder object populated with this object's fields' values.
        Specified by:
        getBuilder in interface Packet
        Specified by:
        getBuilder in class AbstractPacket
        Returns:
        a new Builder object populated with this object's fields values

      • modifier

        protected java.lang.String modifier()

      • length

        public int length()
        Description copied from class: AbstractPacket
        Returns the packet 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
        Overrides:
        length in class AbstractPacket
        Returns:
        the length of the byte stream of the packet represented by this object in bytes

      • getRawData

        public byte[] getRawData()
        Description copied from class: AbstractPacket
        Returns this packet's raw data. This method calls buildRawData() 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. More correctly, this method returns a copy of the cached value, so that the cache can't be changed.
        Specified by:
        getRawData in interface Packet
        Overrides:
        getRawData in class AbstractPacket
        Returns:
        this packet's raw data, namely the byte stream which is actually sent through real network

      • 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
