Method Detail

getOriginateTimestamp

public int getOriginateTimestamp()

Returns:

originateTimestamp

getReceiveTimestamp

public int getReceiveTimestamp()

Returns:

receiveTimestamp

getTransmitTimestamp

public int getTransmitTimestamp()

Returns:

transmitTimestamp

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().

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

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.

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.

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.

Returns:

a calculated hash code value for the object

getHeaderName

protected java.lang.String getHeaderName()

getIdentifier

public short getIdentifier()

Returns:

identifier

getIdentifierAsInt

public int getIdentifierAsInt()

Returns:

identifier

getSequenceNumber

public short getSequenceNumber()

Returns:

sequenceNumber

getSequenceNumberAsInt

public int getSequenceNumberAsInt()

Returns:

sequenceNumber
