org.refcodes.exception.AbstractHiddenException

All Implemented Interfaces:

Serializable, ErrorCodeAccessor, Trap

Direct Known Subclasses:

HiddenException

public abstract class AbstractHiddenException
extends RuntimeException
implements Trap

Base exception for hidden (unchecked) / subsystem exceptions, providing functionality for exception specific multi-language messages. A hidden exception is an exception not representing the behavior of a system by its declared checked and runtime exceptions. Moreover, hidden exceptions may originate from subsystems wrapped by a system without the wrapping system being able to declare the actual subsystem's cause in its declarations (due to e.g. interface compliance reasons). You as a programmer cannot take care to prevent such exception as them may be even undocumented. Such exceptions may be exceptions wrapping an actual cause. Requiring a hidden exceptions may point to problems of your software design, the use of hidden exceptrions should be avoided.

AbstractHiddenException

public AbstractHiddenException(String message,
                               Throwable cause)

AbstractHiddenException

public AbstractHiddenException(Throwable cause)

AbstractHiddenException

public AbstractHiddenException(String aMessage,
                               Throwable aCause,
                               String aErrorCode)

Parameters:

aMessage - - the detail message (which is saved for later retrieval by the Throwable.getMessage() method).

aCause - - the cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

aErrorCode - The exception code to be assigned to the exception. An exception code can be provided when creating an exception and it can be used by the business logic to retrieve a language depended exception message (multi-language support) from a language pack instead of just providing the single language message as being stored by the default exceptions.

Method Detail

getErrorCode

public String getErrorCode()

Description copied from interface: ErrorCodeAccessor

Provides the according exception code. An exception code can be provided when creating an exception and it can be used by the business logic to retrieve a language depended exception message (multi-language support) from a language pack instead of just providing the single language message as being stored by the default exceptions.

Specified by:

getErrorCode in interface ErrorCodeAccessor

Returns:

The exception code in question.
