| Method Summary | |
|---|---|
Object |
get(Object oldInstance)
Returns the replacement object which has been created by the encoder during the instantiation sequence or null if the object has not
been processed yet. |
ExceptionListener |
getExceptionListener()
Returns the currently active ExceptionListener instance. |
PersistenceDelegate |
getPersistenceDelegate(Class<?> type)
|
Object |
remove(Object oldInstance)
|
void |
setExceptionListener(ExceptionListener listener)
Sets the ExceptionListener instance to be used for reporting
recorable exceptions in the instantiation and initialization sequence. |
void |
setPersistenceDelegate(Class<?> type,
PersistenceDelegate delegate)
Sets the PersistenceDelegate instance for the given class. |
void |
writeExpression(Expression expr)
Note: If you call this method not from within an object instantiation and initialization sequence it will be silently ignored. |
protected void |
writeObject(Object o)
|
void |
writeStatement(Statement stmt)
Note: If you call this method not from within an object instantiation and initialization sequence it will be silently ignored. |

protected void writeObject(Object o)
public void setExceptionListener(ExceptionListener listener)
ExceptionListener instance to be used for reporting
recorable exceptions in the instantiation and initialization sequence. If
the argument is null a default instance will be used that
prints the thrown exception to System.err.
public ExceptionListener getExceptionListener()
ExceptionListener instance.
public PersistenceDelegate getPersistenceDelegate(Class<?> type)
public void setPersistenceDelegate(Class<?> type,
PersistenceDelegate delegate)
PersistenceDelegate instance for the given class.
Note: Throws a NullPointerException if the argument is
null.
Note: Silently ignores PersistenceDelegates for Array types and primitive wrapper classes.
Note: Although this method is not declared static changes to
the PersistenceDelegates affect all
Encoder instances. In this implementation the
access is thread safe.
public Object remove(Object oldInstance)
public Object get(Object oldInstance)
null if the object has not
been processed yet.
Note: The String class acts as an endpoint for the
inherently recursive algorithm of the Encoder. Therefore instances
of String will always be returned by this method. In other
words the assertion:
assert (anyEncoder.get(anyString) == anyString)
Note: If null is requested, the result will
always be null.
public void writeStatement(Statement stmt)
Note: If you call this method not from within an object instantiation and initialization sequence it will be silently ignored.
public void writeExpression(Expression expr)
Note: If you call this method not from within an object instantiation and initialization sequence it will be silently ignored.
