All Implemented Interfaces:

Serializable, NlsObject, NlsThrowable

Direct Known Subclasses:

NlsRuntimeException

public abstract class AbstractNlsRuntimeException
extends RuntimeException
implements NlsThrowable

This is an abstract base implementation of an unchecked exception with real native language support (NLS).
ATTENTION:
Please prefer extending NlsRuntimeException instead of this class.
INFORMATION:
Unchecked exceptions should be used for technical errors and should only occur in unexpected situations.

Since:

1.0.0

Constructor Detail

AbstractNlsRuntimeException

public AbstractNlsRuntimeException(NlsMessage message)

The constructor.

Parameters:

message - the message describing the problem briefly.

AbstractNlsRuntimeException

public AbstractNlsRuntimeException(Throwable nested,
                                   NlsMessage message)

The constructor.

Parameters:

nested - is the cause of this exception.

message - the message describing the problem briefly.

Method Detail

createUuid

protected UUID createUuid()

This method creates a new UUID.

Returns:

the new UUID or null to turn this feature off.

getUuid

public final UUID getUuid()

This method gets the UUID of this exception. The UUID is created when the exception is constructed or copied from the given cause if it is also a NlsThrowable.
The UUID will appear in the printed stacktrace but NOT in the message and should therefore be written to log-files if the NlsThrowable is logged. If you supply the UUID to the end-user in case of an unexpected error, he can easily find the stacktrace in the log-files.

Specified by:

getUuid in interface NlsThrowable

Returns:

the UUID of this exception. It may be null if this feature is turned of (it is turned on by default).

getNlsMessage

public final NlsMessage getNlsMessage()

This method gets the NlsMessage describing the problem.

Specified by:

getNlsMessage in interface NlsThrowable

Returns:

the NlsMessage.

printStackTrace

public void printStackTrace(PrintStream s)

Overrides:

printStackTrace in class Throwable

printStackTrace

public void printStackTrace(PrintWriter s)

Overrides:

printStackTrace in class Throwable

printStackTrace

public void printStackTrace(Locale locale,
                            NlsTemplateResolver resolver,
                            Appendable buffer)

This method prints the stack trace with localized exception message(s).

Specified by:

printStackTrace in interface NlsThrowable

Parameters:

locale - is the locale to translate to.

resolver - translates the original message.

buffer - is where to write the stack trace to.

printStackTrace

public void printStackTrace(Locale locale,
                            Appendable buffer)

This method prints the stack trace with localized exception message(s).

Specified by:

printStackTrace in interface NlsThrowable

Parameters:

locale - is the locale to translate to.

buffer - is where to write the stack trace to.

getMessage

public String getMessage()

Specified by:

getMessage in interface NlsThrowable

Overrides:

getMessage in class Throwable

Returns:

the message.

getLocalizedMessage

public String getLocalizedMessage(Locale locale)

This method gets the localized message as string.

Specified by:

getLocalizedMessage in interface NlsThrowable

Parameters:

locale - is the locale to translate to.

Returns:

the localized message.

See Also:

NlsThrowable.getLocalizedMessage(Locale, NlsTemplateResolver, Appendable)

getLocalizedMessage

public String getLocalizedMessage(Locale locale,
                                  NlsTemplateResolver resolver)

This method gets the localized message as string.

Specified by:

getLocalizedMessage in interface NlsThrowable

Parameters:

locale - is the locale to translate to.

resolver - is used to resolve the template in order to translate the original i18n message.

Returns:

the localized message.

See Also:

NlsThrowable.getLocalizedMessage(Locale, NlsTemplateResolver, Appendable)

getLocalizedMessage

public void getLocalizedMessage(Locale locale,
                                NlsTemplateResolver resolver,
                                Appendable buffer)

This method writes the localized message to the given string buffer.

Specified by:

getLocalizedMessage in interface NlsThrowable

Parameters:

locale - is the locale to translate to.

resolver - is used to resolve the template required to translate the internationalized message.

buffer - is the buffer where to write the message to.

See Also:

NlsMessage.getLocalizedMessage(Locale, NlsTemplateResolver, Appendable)

toNlsMessage

public NlsMessage toNlsMessage()

This method is the equivalent to Object.toString() with native language support.

Specified by:

toNlsMessage in interface NlsObject

Returns:

an nls message representing this object.
