A Framework for all Mapheads out there
What is this Framework about?
- generate pojos for easy map interactions (@MapWrapper)
- entity framework for all databases which represents it’s data in maps (@Entity)
- serialise/deserialise objects of complex classes in maps (@Mapper)
Quick View
@Entity / @MapWrapper
@Entity(database = "mydb_db")
@Fields(
Field(name = "type", type = String::class, defaultValue = "product", readonly = true),
Field(name = "name", type = String::class),
Field(name = "comments", type = UserComment::class, list = true),
Field(name = "image", type = Blob::class),
Field(name = "identifiers", type = String::class, list = true)
)
@Queries(
Query(fields = ["type"])
)
open class Product
@MapWrapper
@Fields(
Field(name = "comment", type = String::class),
Field(name = "user", type = String::class, defaultValue = "anonymous"),
Field("age", type = Integer::class, defaultValue = "0")
)
open class UserComment
Result
ProductEntity
.create()
.builder()
.setName("Beer")
.setComments(listOf(UserCommentWrapper
.create()
.builder()
.setComment("very awesome")
.exit()))
.setImage(Blob("image/jpeg", resources.openRawResource(R.raw.ic_kaufland_placeholder)))
.exit()
.save()
val allEntitiesOfType = ProductEntity.findByType()
val resultOfAComplexQuery = ProductEntity.someComplexQuery("foo")
@Mapper
@Mapper
class MyViewModel : ViewModel() {
@Mapify
var innerObjectList: List<MyMapifyableTest> = listOf(MyMapifyableTest(simple))
@Mapify
var innerObjectMap: Map<String, MyMapifyableTest> = mapOf("test" to MyMapifyableTest(simple))
@Mapify
var testSerializable: TestSerializable = TestSerializable(simple, 5)
@Mapify(nullableIndexes = [0])
var product: ProductEntity? = null
@Mapify
var booleanValue: Boolean = true
@Mapify(nullableIndexes = [0])
var bigDecimalValue: BigDecimal? = null
}
Result
// This is generated by the Annotation Processor
val mapper = MyViewModelMapper()
val oldObj = ViewModelProvider(this).get(MyViewModel::class.java)
// Save obj to Map
val mapToPersist = mapper.toMap(oldObj)
val newObj = ViewModelProvider(this).get(MyViewModel::class.java)
// restore obj
mapper.fromMap(newObj, mapToPersist)
