Constructor Details

IIOPInputStream

public IIOPInputStream()
                throws IOException

Dummy constructor; passes upper stream a dummy stream;

Throws:

IOException

Method Details

getStreamFormatVersion

protected byte getStreamFormatVersion()

Specified by:

getStreamFormatVersion in class InputStreamHook

setTestFVDFlag

public static void setTestFVDFlag(boolean val)

setSender

public final void setSender(CodeBase cb)

getSender

public final CodeBase getSender()

setValueHandler

public final void setValueHandler(ValueHandler vh)

getValueHandler

public final ValueHandler getValueHandler()

readObjectDelegate

public final Object readObjectDelegate()
                                throws IOException

Override the actions of the final method "readObject()" in ObjectInputStream.

Throws:

ClassNotFoundException - Class of a serialized object cannot be found.

InvalidClassException - Something is wrong with a class used by serialization.

StreamCorruptedException - Control information in the stream is inconsistent.

OptionalDataException - Primitive data was found in the stream instead of objects.

IOException - Any of the usual Input/Output related exceptions.

Since:

JDK1.1.6 Read an object from the ObjectInputStream. The class of the object, the signature of the class, and the values of the non-transient and non-static fields of the class and all of its supertypes are read. Default deserializing for a class can be overriden using the writeObject and readObject methods. Objects referenced by this object are read transitively so that a complete equivalent graph of objects is reconstructed by readObject.

The root object is completly restored when all of its fields and the objects it references are completely restored. At this point the object validation callbacks are executed in order based on their registered priorities. The callbacks are registered by objects (in the readObject special methods) as they are individually restored. Exceptions are thrown for problems with the InputStream and for classes that should not be deserialized. All exceptions are fatal to the InputStream and leave it in an indeterminate state; it is up to the caller to ignore or recover the stream state., JDK1.1

simpleSkipObject

public final void simpleSkipObject(String repositoryID,
 CodeBase sender)

readObjectOverride

protected final Object readObjectOverride()
                                   throws OptionalDataException,
ClassNotFoundException,
IOException

This method is called by trusted subclasses of ObjectOutputStream that constructed ObjectOutputStream using the protected no-arg constructor. The subclass is expected to provide an override method with the modifier "final".

Overrides:

readObjectOverride in class ObjectInputStream

Returns:

the Object read from the stream.

Throws:

OptionalDataException

ClassNotFoundException

IOException

Since:

JDK 1.2

See Also:

• #ObjectInputStream()
• ObjectInputStream.readObject()

enableResolveObjectDelegate

public final boolean enableResolveObjectDelegate(boolean enable)

Override the actions of the final method "enableResolveObject()" in ObjectInputStream.

Throws:

SecurityException - The classloader of this stream object is non-null.

Since:

JDK1.1.6 Enable the stream to allow objects read from the stream to be replaced. If the stream is a trusted class it is allowed to enable replacment. Trusted classes are those classes with a classLoader equals null.

When enabled the resolveObject method is called for every object being deserialized., JDK1.1
