toString
public java.lang.String toString()
- Description copied from class:
java.lang.Object
- Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into System.out.println() 55
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a java.lang.RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null, string concatenation will instead
use "null".
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode()).
size
public long size()
- Description copied from class:
org.jgroups.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.
type2String
public static java.lang.String type2String(int t)
writeExternal
public void writeExternal(java.io.ObjectOutput out)
throws java.io.IOException
- Description copied from interface:
java.io.Externalizable
- This method is responsible for writing the instance data of an object
to the passed in stream. Note that this stream is not a subclass of
OutputStream, but rather is a class that implements the
ObjectOutput interface. That interface provides a
number of methods
for writing Java data values to a stream.
Not that the implementation of this method must be coordinated with
the implementation of readExternal.
readExternal
public void readExternal(java.io.ObjectInput in)
throws java.io.IOException,
java.lang.ClassNotFoundException
- Description copied from interface:
java.io.Externalizable
- This method restores an object's state by reading in the instance data
for the object from the passed in stream. Note that this stream is not
a subclass of
InputStream, but rather is a class that
implements
the ObjectInput interface. That interface provides a
mechanism for
reading in Java data types from a stream.
Note that this method must be compatible with writeExternal.
It must read back the exact same types that were written by that
method in the exact order they were written.
If this method needs to read back an object instance, then the class
for that object must be found and loaded. If that operation fails,
then this method throws a ClassNotFoundException
