Method Detail

writeObject

public void writeObject(ObjectOutput output,
                        K key)
                 throws IOException

Description copied from interface: Externalizer

Writes the object reference to the stream.

Specified by:

writeObject in interface Externalizer<K extends Key<String>>

Parameters:

output - the object output to write to

key - the object reference to write

Throws:

IOException - if an I/O error occurs

readObject

public K readObject(ObjectInput input)
             throws IOException,

readObject in interface Externalizer<K extends Key<String>>

Parameters:

input - the object input from which to read

Returns:

the object instance

Throws:

IOException - if an I/O error occurs

ClassNotFoundException - if a class could not be found

getTargetClass

public Class<? extends K> getTargetClass()

Description copied from interface: Externalizer

Returns the target class of the object to externalize.

Specified by:
