メソッドの詳細

newPacket

public static PppPacket newPacket(byte[] rawData,
                                  int offset,
                                  int length)
                           throws IllegalRawDataException

A static factory method. This method validates the arguments by ByteArrays.validateBounds(byte[], int, int), which may throw exceptions undocumented here.

パラメータ:

rawData - rawData

offset - offset

length - length

戻り値:

a new PppPacket object.

例外:

IllegalRawDataException - if parsing the raw data fails.

getHeader

public PppPacket.PppHeader getHeader()

クラスからコピーされた説明: 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.

定義:

getHeader インタフェース内 Packet

戻り値:

the Header object representing this packet's header. May be null if the header doesn't exist

getBuilder

public PppPacket.Builder getBuilder()

インタフェースからコピーされた説明: Packet

Returns a new Builder object populated with this object's fields' values.

定義:

getBuilder インタフェース内 Packet

定義:

getBuilder クラス内 AbstractPacket

戻り値:

a new Builder object populated with this object's fields values

getPayload

public Packet getPayload()

クラスからコピーされた説明: 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.

定義:

getPayload インタフェース内 Packet

オーバーライド:

getPayload クラス内 AbstractPacket

戻り値:

the Packet object representing this packet's payload. May be null if the payload doesn't exist

getPad

public byte[] getPad()

戻り値:

pad

calcLength

protected int calcLength()

クラスからコピーされた説明: 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.

オーバーライド:

calcLength クラス内 AbstractPacket

戻り値:

a calculated length

buildRawData

protected byte[] buildRawData()

クラスからコピーされた説明: 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.

オーバーライド:

buildRawData クラス内 AbstractPacket

戻り値:

a raw data built

buildString

protected String buildString()

クラスからコピーされた説明: 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.

オーバーライド:

buildString クラス内 AbstractPacket

戻り値:

a string representation of this object

equals

public boolean equals(Object obj)

クラスからコピーされた説明: 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.

オーバーライド:

equals クラス内 AbstractPacket

calcHashCode

protected int calcHashCode()

クラスからコピーされた説明: 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.

オーバーライド:

calcHashCode クラス内 AbstractPacket

戻り値:

a calculated hash code value for the object
