Method Detail

isTechnical

public boolean isTechnical()

Description copied from interface: NlsThrowable

Determines if this is a technical exception.

• A technical exception is an unexpected situation that is to be logged on error level and should be analyzed by the operators or software developers of the system. Further in such case the end-user can typically do nothing about the problem (except to retry his operation) and will typically not understand the problem. Therefore a generic message should be displayed to the end-user in such case. See TechnicalErrorUserException.
• A non technical exception is called user failure. It is an undesired but NOT abnormal situation. It should be logged on a level less than error (typically info). The message is typically intended for to end-users and has to be easy to understand.

This separation is intentionally not done via inheritance of technical and business exception base classes to allow reuse. However, if you want to have it this way, create such classes derived from NlsRuntimeException.

Specified by:

isTechnical in interface NlsThrowable

Overrides:

isTechnical in class NlsRuntimeException

Returns:

true if this is a technical exception, false if this is a user error.
