Constructor Summary

UMException()
This constructor should not be used because it does not reveal any error information to the caller.

Constructor with nested exception and additional explanation text.

Method Summary

void	addMessage(IMessage message) Adds a message to the message buffer of this exception.
String	getLocalizedMessage() Returns the message text of the exception and of all nested exceptions in concatenated form.
String	getMessage() The same as getLocalizedMessage(), but using getMessage() first and if nothing delivered from there then using getLocalizedMessage().
Iterator	getMessages(boolean clearPermanentMessages) Returns an iterator which contains the IMessage objects assigned to this IPrincipal or null if no messages are assigned.
Throwable	getNestedException() Return the nested exception.
static void	main(String[] args) Quick demonstration how this exception works
void	printStackTrace() Print the stack trace and the stack trace of the nested exception (if present) to the error stream.
void	printStackTrace(PrintStream s) Write a stack trace to a PrintStream.
void	printStackTrace(PrintWriter s) Write a stack trace to a PrintWriter.

Constructor Detail

UMException

public UMException(Throwable nestedException,
                   String message)

Constructor with nested exception and additional explanation text.

Parameters:

nestedException - The exception that is wrapped into the PersistenceException.

message - A String with the message of the PersistenceException. Callers should not repeat the message text of the nested exception becasue its message is already printed out automatically.

UMException

public UMException(Throwable nestedException)

Constructor for PersistenceException wrapping another exception.

Parameters:

nestedException - The wrapped exception.

UMException

public UMException(String message)

UMException

public UMException()

This constructor should not be used because it does not reveal any error information to the caller.

Method Detail

addMessage

public void addMessage(IMessage message)

Adds a message to the message buffer of this exception.

Parameters:

message - The message to add at the end of the message buffer.

getNestedException

public Throwable getNestedException()

Return the nested exception.

Returns:

The wrapped exception, or null if there is none.

printStackTrace

public void printStackTrace()

Print the stack trace and the stack trace of the nested exception (if present) to the error stream.

Overrides:

printStackTrace in class Throwable

printStackTrace

public void printStackTrace(PrintStream s)

Write a stack trace to a PrintStream.

Overrides:

printStackTrace in class Throwable

Parameters:

s - A PrintStream.

printStackTrace

public void printStackTrace(PrintWriter s)

Write a stack trace to a PrintWriter.

Overrides:

printStackTrace in class Throwable

Parameters:

s - A PrintWriter.

getLocalizedMessage

public String getLocalizedMessage()

Returns the message text of the exception and of all nested exceptions in concatenated form. The message texts of this exception and of the nested exceptions are determined by calling method getLocalizedMessage() on the respective objects. If the method does not return a useful content (which might be the case for faulty implementations of exceptions), then the getMessage() method is used instead. Better any information than no information at all. The concatenation recogminzes if the nested exception starts with the same text as the wrapping exception and in this case removes the duplicate parts. This avoids duplicate appearance of the same message if when filling the UMException the caller fills in a nested exception and uses its texts as the message text for the wrapper itself.

Overrides:

getLocalizedMessage in class Throwable

Returns:

The most information about the exception and the nested exception as possible.

getMessage

public String getMessage()

The same as getLocalizedMessage(), but using getMessage() first and if nothing delivered from there then using getLocalizedMessage().

Overrides:

getMessage in class Throwable

See Also:

getLocalizedMessage()

getMessages

public Iterator getMessages(boolean clearPermanentMessages)

Returns an iterator which contains the IMessage objects assigned to this IPrincipal or null if no messages are assigned. If the method is called with parameter true, every subsequent call will return null if no new message was assigned to this IPrincipal.

Parameters:

clearPermanentMessages - Specifies whether permanent messages with life time IMessage.LIFETIME_PERMANENT should be removed from the message buffer.

Returns:

The messages assigned to this IPrincipal object or null.

main

public static void main(String[] args)
