public byte getType()

getSeqno

public long getSeqno()

getRange

public Range getRange()

getSender

public Address getSender()

writeTo

public void writeTo(java.io.DataOutput out)
             throws java.lang.Exception
Description copied from interface: Streamable
Write the entire state of the current object (including superclasses) to outstream. Note that the output stream must not be closed

Throws:
java.lang.Exception

readFrom

public void readFrom(java.io.DataInput in)
              throws java.lang.Exception
Description copied from interface: Streamable
Read the state of the current object (including superclasses) from instream Note that the input stream must not be closed

Throws:
java.lang.Exception

size

public int size()
Description copied from class: Header
To be implemented by subclasses. Return the size of this object for the serialized version of it. I.e. how many bytes this object takes when flattened into a buffer. This may be different for each instance, or can be the same. This may also just be an estimation. E.g. FRAG uses it on Message to determine whether or not to fragment the message. Fragmentation itself will be accurate, because the entire message will actually be serialized into a byte buffer, so we can determine the exact size.

Specified by:
size in class Header

copy

public NakAckHeader copy()

type2Str

public static java.lang.String type2Str(byte t)

toString

public java.lang.String toString()
Overrides:
