26 | * Default base class for SRU client response handlers. |
---|
27 | * <p> |
---|
28 | * This class is available as a convenience base class for SRU client |
---|
29 | * applications: it provides default implementations for all of the callbacks in |
---|
30 | * the three request handler handler classes: |
---|
31 | * </p> |
---|
32 | * <ul> |
---|
33 | * <li>{@link SRUExplainHandler}</li> |
---|
34 | * <li>{@link SRUScanHandler}</li> |
---|
35 | * <li>{@link SRUSearchRetrieveHandler}</li> |
---|
36 | * </ul> |
---|
37 | * <p> |
---|
38 | * Application writers can extend this class when they need to implement only |
---|
39 | * part of an interface; parser writers can instantiate this class to provide |
---|
40 | * default handlers when the application has not supplied its own. |
---|
41 | * </p> |
