Component Replacement

Business Components provide a simple extension mechanism where base-package code can be made available to be replaced by customizations. For this to take place, two things must happen:

An example replacement of the PersonFinders component is shown below. Component implementations are registered in the same order as the application stack, that is: base followed by ccb, then followed by cm. After the component is defined in one application, derived applications (higher on the stack) can replace the implementation.


package com.abcutilities.cis.customizations.person;
/**
 * @BusinessComponent
 *   (replacementComponent = true)
 */
public class CustomizedPersonFindersImpl 
    extends GenericBusinessComponent 
    implements PersonFinders {

    public Integer findCountByNameType(PerOrBusLookup nameType) {
        ... customized code ...
    }
    ...
}
