MarshalledObject JDK 1.6)

Description

publicfinal class MarshalledObject

A MarshalledObject contains a byte stream with the serialized representation of an object given to its constructor.

A MarshalledObject contains a byte stream with the serialized representation of an object given to its constructor. The get method returns a new copy of the original object, as deserialized from the contained byte stream. The contained object is serialized and deserialized with the same serialization semantics used for marshaling and unmarshaling parameters and return values of RMI calls: When the serialized form is created:

classes are annotated with a codebase URL from where the class can be loaded (if available), and
any remote object in the MarshalledObject is represented by a serialized instance of its stub.

When copy of the object is retrieved (via the get method), if the class is not available locally, it will be loaded from the appropriate location (specified the URL annotated with the class descriptor when the class was serialized.

MarshalledObject facilitates passing objects in RMI calls that are not automatically deserialized immediately by the remote peer.

Constructors

public MarshalledObject ( T obj) throws IOException

Creates a new MarshalledObject that contains the serialized representation of the current state of the supplied object.

Creates a new MarshalledObject that contains the
serialized representation of the current state of the supplied object.
The object is serialized with the semantics used for marshaling
parameters for RMI calls.
Parameters:
- obj - the object to be serialized (must be serializable)
Throws:
- IOException - if an IOException occurs; an IOException may occur if obj is not serializable.
Since: 1.2

Methods

Hide/Show inherited methods

public boolean equals (Object obj)

Compares this MarshalledObject to another object.

Compares this MarshalledObject to another object.
Returns true if and only if the argument refers to a
MarshalledObject that contains exactly the same
serialized representation of an object as this one does. The
comparison ignores any class codebase annotation, meaning that
two objects are equivalent if they have the same serialized
representation except for the codebase of each class
in the serialized representation.
Returns: true if the argument contains an equaivalent serialized object; false otherwise
Parameters:
- obj - the object to compare with this MarshalledObject
Since: 1.2

public T get () throws IOException ClassNotFoundException

Returns a new copy of the contained marshalledobject.

Returns a new copy of the contained marshalledobject. The internal
representation is deserialized with the semantics used for
unmarshaling paramters for RMI calls.
Returns: a copy of the contained object
Throws:
- IOException - if an IOException occurs while deserializing the object from its internal representation.
- ClassNotFoundException - if a ClassNotFoundException occurs while deserializing the object from its internal representation. could not be found
Since: 1.2

public int hashCode ()

Return a hash code for this MarshalledObject.

Return a hash code for this MarshalledObject.
Returns: a hash code
