从类复制的说明: 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.

指定者:

copy

public UNICAST2.Unicast2Header copy()

writeTo

public void writeTo(java.io.DataOutput out)
             throws java.lang.Exception

从接口复制的说明: Streamable

Write the entire state of the current object (including superclasses) to outstream. Note that the output stream must not be closed

抛出:

java.lang.Exception

readFrom

public void readFrom(java.io.DataInput in)
              throws java.lang.Exception

从接口复制的说明: Streamable

Read the state of the current object (including superclasses) from instream Note that the input stream must not be closed

抛出:
