Class MarshalledObject<T>
- Serializable
A
MarshalledObject
consists of a serialized object which is
marshalled according to the RMI specification.
An object passed to the constructor is serialized and tagged with the needed
URL to retrieve its class definition for remote usage. If the object is a
remote reference its stub is serialized instead. The instance of this
marshalled object can be later retrieved by its
get()
method.
boolean | equals(Object obj) - Checks if the given object is equal to this marshalled object.
|
T | get() - Constructs and returns a copy of the internal serialized object.
|
int | hashCode() - Get a value that represents this Object, as uniquely as
possible within the confines of an int.

MarshalledObject
public MarshalledObject(T obj)
throws IOException
Constructs a MarshalledObject
from the given object.
obj
- the object to marshal
IOException
- if an I/O error during serialization occurs.
equals
public boolean equals(Object obj)
Checks if the given object is equal to this marshalled object.
Marshalled objects are considered equal if they contain the
same serialized object. Codebase annotations where the class
definition can be downloaded are ignored in the equals test.
- equals in interface Object
obj
- the object to compare.
true
if equal, false
otherwise.
hashCode
public int hashCode()
Get a value that represents this Object, as uniquely as
possible within the confines of an int.
There are some requirements on this method which
subclasses must follow:
- Semantic equality implies identical hashcodes. In other
words, if
a.equals(b)
is true, then
a.hashCode() == b.hashCode()
must be as well.
However, the reverse is not necessarily true, and two
objects may have the same hashcode without being equal. - It must be consistent. Whichever value o.hashCode()
returns on the first invocation must be the value
returned on all later invocations as long as the object
exists. Notice, however, that the result of hashCode may
change between separate executions of a Virtual Machine,
because it is not invoked on the same object.
Notice that since
hashCode
is used in
Hashtable
and other hashing classes,
a poor implementation will degrade the performance of hashing
(so don't blindly implement it as returning a constant!). Also,
if calculating the hash is time-consuming, a class may consider
caching the results.
The default implementation returns
System.identityHashCode(this)
- hashCode in interface Object
- the hash code for this Object
