Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class Header

type2String

public static java.lang.String type2String(byte type)

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.

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

Throws:

java.lang.Exception
