readAnnotation(ObjectStreamClass desc)
Reads and returns a class annotation string value (possibly
null) that was
written by a corresponding AnnotatedObjectOutputStream implementation. |
protected ObjectStreamClass |
readClassDescriptor()
Overrides the super method and tries to get the class descriptor from a local map.

Reads a repetitive object which was written by
MarshalOutputStream.writeRepetitiveObject(java.lang.Object). |

resolveClass(ObjectStreamClass classDesc)
Resolves the appropriate
Class object for the stream class descriptor
classDesc. |

names interfaceNames. |

Class object for the stream class descriptor
classDesc.
MarshalInputStream implements this method as follows:
First tries to check if this class descriptor was already resolved if it does return the class.
Else invokes the super class implementation.

AnnotatedObjectInputStreamnull) that was
written by a corresponding AnnotatedObjectOutputStream implementation.
AnnotatedObjectInputStream implements this method to just read the annotation
value from this stream using readUnshared, and if
readUnshared returns a non-null value that is not a
String, an InvalidObjectException is thrown.
A subclass can override this method to read the annotation from a different location.
