A cohesive attempt to assimilate these concerns into the mainstream flow of the system would result in the effect of scattering and tangling. For example, when writing an application for a medical records, indexing diagnosis reports may be a core concern but logging the history of record changes to the database, or checking whether a client has the authority to execute a transaction on a particular object in the database are some of the unavoidable cross-cutting concerns that should be taken into account while designing/implementating of the system. ![]() Interceptors are commonly used when a business method on a target class is invoked on life cycle events to create/destroy or timeout, such as, found when implementing profiling, auditing, logging, and so forth. In Java, they are nothing more than components, colored to implement cross-cutting concerns, that are mainly used to intercept EJB method calls or invocation of life-cycle events on an associated target class. ![]() The Interceptor class is the object-oriented way to handle such situations. These concerns can neither be decomposed from the rest of the system nor they can be streamlined with the system flow: A system outcast who is too important to be ignored yet too unbiased to be coalesced with the system counterpart.
