aoqi@0 | 27 | * Given an input object maps to an appropriate output object. A mapper may |
aoqi@0 | 28 | * variously provide a mapping between types, object instances or keys and |
aoqi@0 | 29 | * values or any other form of transformation upon the input. |
aoqi@0 | 30 | * |
aoqi@0 | 31 | * <p/>All mapper implementations are expected to: |
aoqi@0 | 32 | * <ul> |
aoqi@0 | 33 | * <li>Provide stable results such that for any {@code t} the result of two |
aoqi@0 | 34 | * {@code map} operations are always equivalent. ie.<pre> |
aoqi@0 | 35 | * Foo one = mapper.map(a); |
aoqi@0 | 36 | * Foo two = mapper.map(a); |
aoqi@0 | 37 | * |
aoqi@0 | 38 | * assert one.equals(two) && two.equals(one); |
aoqi@0 | 39 | * </pre></li> |
aoqi@0 | 40 | * <li>Equivalent input objects should map to equivalent output objects. ie.<pre> |
aoqi@0 | 41 | * assert a.equals(b); // a and b are equivalent |
aoqi@0 | 42 | * |
aoqi@0 | 43 | * Foo x = mapper.map(a); |
aoqi@0 | 44 | * Foo y = mapper.map(b); |
aoqi@0 | 45 | * |
aoqi@0 | 46 | * assert x.equals(y); // their mapped results should be as equivalent. |
aoqi@0 | 47 | * </pre></li> |
aoqi@0 | 48 | * <li>The mapper should not modify the input object in any way that would |
aoqi@0 | 49 | * change the mapping.</li> |
aoqi@0 | 50 | * <li>When used for aggregate operations upon many elements mappers |
aoqi@0 | 51 | * should not assume that the {@code map} operation will be called upon elements |
aoqi@0 | 52 | * in any specific order.</li> |
aoqi@0 | 53 | * </ul> |
aoqi@0 | 54 | * |
aoqi@0 | 55 | * @param <R> the type of output objects from {@code map} operation. May be the |
aoqi@0 | 56 | * @param <T> the type of input objects provided to the {@code map} operation. |
aoqi@0 | 57 | * same type as {@code <T>}. |
