Constructor Detail

CommandLineUsageException

public CommandLineUsageException()

Default constructor, for an exception with no nested exception and no message.

CommandLineUsageException

public CommandLineUsageException(java.lang.Throwable exception)

Constructs an exception containing another exception, but no message of its own.

Parameters:

exception - the exception to contain

CommandLineUsageException

public CommandLineUsageException(java.lang.String message)

Constructs an exception containing an error message, but no nested exception.

Parameters:

message - the message to associate with this exception

CommandLineUsageException

public CommandLineUsageException(java.lang.String message,
                                 java.lang.Throwable exception)

Constructs an exception containing another exception and a message.

Parameters:

message - the message to associate with this exception

exception - the exception to contain

CommandLineUsageException

public CommandLineUsageException(java.lang.String bundleName,
                                 java.lang.String messageKey,
                                 java.lang.String defaultMsg)

Constructs an exception containing a resource bundle name, a message key, and a default message (in case the resource bundle can't be found). Using this constructor is equivalent to calling the CommandLineUsageException(String,String,String,Object[]) constructor, with a null pointer for the Object[] parameter. Calls to NestedException.getMessage(java.util.Locale) will attempt to retrieve the top-most message (i.e., the message from this exception, not from nested exceptions) by querying the named resource bundle. Calls to NestedException.printStackTrace(PrintWriter,java.util.Locale) will do the same, where applicable. The message is not retrieved until one of those methods is called, because the desired locale is passed into getMessage() and printStackTrace(), not this constructor.

Parameters:

bundleName - resource bundle name

messageKey - the key to the message to find in the bundle

defaultMsg - the default message

CommandLineUsageException(String,String,String,Object[]), NestedException.getMessage(java.util.Locale)

CommandLineUsageException

public CommandLineUsageException(java.lang.String bundleName,
                                 java.lang.String messageKey,
                                 java.lang.String defaultMsg,
                                 java.lang.Object[] msgParams)

Constructs an exception containing a resource bundle name, a message key, and a default message (in case the resource bundle can't be found). Using this constructor is equivalent to calling the CommandLineUsageException(String,String,String,Object[],Throwable) constructor, with a null pointer for the Throwable parameter. Calls to NestedException.getMessage(java.util.Locale) will attempt to retrieve the top-most message (i.e., the message from this exception, not from nested exceptions) by querying the named resource bundle. Calls to NestedException.printStackTrace(PrintWriter,java.util.Locale) will do the same, where applicable. The message is not retrieved until one of those methods is called, because the desired locale is passed into getMessage() and printStackTrace(), not this constructor.

Parameters:

bundleName - resource bundle name

messageKey - the key to the message to find in the bundle

defaultMsg - the default message

msgParams - parameters to the message, if any, or null

CommandLineUsageException

public CommandLineUsageException(java.lang.String bundleName,
                                 java.lang.String messageKey,
                                 java.lang.String defaultMsg,
                                 java.lang.Throwable exception)

Constructs an exception containing a resource bundle name, a message key, a default message (in case the resource bundle can't be found), and another exception. Using this constructor is equivalent to calling the CommandLineUsageException(String,String,String,Object[],Throwable) constructor, with a null pointer for the Object[] parameter. Calls to NestedException.getMessage(java.util.Locale) will attempt to retrieve the top-most message (i.e., the message from this exception, not from nested exceptions) by querying the named resource bundle. Calls to NestedException.printStackTrace(PrintWriter,java.util.Locale) will do the same, where applicable. The message is not retrieved until one of those methods is called, because the desired locale is passed into getMessage() and printStackTrace(), not this constructor.

Parameters:

bundleName - resource bundle name

messageKey - the key to the message to find in the bundle

defaultMsg - the default message

exception - the exception to nest

CommandLineUsageException

public CommandLineUsageException(java.lang.String bundleName,
                                 java.lang.String messageKey,
                                 java.lang.String defaultMsg,
                                 java.lang.Object[] msgParams,
                                 java.lang.Throwable exception)

Constructs an exception containing a resource bundle name, a message key, a default message format (in case the resource bundle can't be found), arguments to be incorporated in the message via java.text.MessageFormat, and another exception. Calls to NestedException.getMessage(java.util.Locale) will attempt to retrieve the top-most message (i.e., the message from this exception, not from nested exceptions) by querying the named resource bundle. Calls to NestedException.printStackTrace(PrintWriter,java.util.Locale) will do the same, where applicable. The message is not retrieved until one of those methods is called, because the desired locale is passed into getMessage() and printStackTrace(), not this constructor.

Parameters:

bundleName - resource bundle name

messageKey - the key to the message to find in the bundle

defaultMsg - the default message

msgParams - parameters to the message, if any, or null

exception - exception to be nested
