Method Detail

readObjectUnshared

java.lang.Object readObjectUnshared()
                             throws java.lang.ClassNotFoundException,
                                    java.io.IOException

Read and return an unshared object.

Returns:

an unshared object

Throws:

java.lang.ClassNotFoundException - if the class of a serialized object cannot be found

java.io.IOException - if an error occurs

readObject

<T> T readObject(java.lang.Class<T> type)
          throws java.lang.ClassNotFoundException,
                 java.io.IOException

Read and return an object, cast to a specific type.

Type Parameters:

T - the object type

Parameters:

type - the object class

Returns:

the object read from the stream

Throws:

java.lang.ClassNotFoundException - if the class of a serialized object cannot be found

java.io.InvalidObjectException - if the object is not of the expected type

java.io.IOException - if an error occurs

readObjectUnshared

<T> T readObjectUnshared(java.lang.Class<T> type)
                  throws java.lang.ClassNotFoundException,
                         java.io.IOException

Read and return an unshared object, cast to a specific type.

Type Parameters:

T - the object type

Parameters:

type - the object class

Returns:

an unshared object

Throws:

java.lang.ClassNotFoundException - if the class of a serialized object cannot be found

java.io.InvalidObjectException - if the object is not of the expected type

java.io.IOException - if an error occurs

start

void start(ByteInput newInput)
    throws java.io.IOException

Begin unmarshalling from a stream.

Parameters:

newInput - the new stream

Throws:

java.io.IOException - if an error occurs during setup, such as an invalid header

clearInstanceCache

void clearInstanceCache()
                 throws java.io.IOException

Discard the instance cache.

Throws:

java.io.IOException - if an error occurs

clearClassCache

void clearClassCache()
              throws java.io.IOException

Discard the class cache. Implicitly also discards the instance cache.

Throws:

java.io.IOException - if an error occurs

finish

void finish()
     throws java.io.IOException

Finish unmarshalling from a stream. Any transient class or instance cache is discarded.

Throws:

java.io.IOException - if an error occurs
