io.vertx.tp.atom.modeling.reference.RResult

All Implemented Interfaces:

Serializable

public class RResult
extends Object
implements Serializable

## Result ### 1. Intro Processing result based on configuration `connect` defined, different situation could trigger different joining Here are three critical concept: 1. Name: Mapped to `X_ATTRIBUTE` field `NAME`, it's the model attribute name. 2. SourceField: Mapped to reference field name. 3. JoinField: it's defined by `connect` configuration. ### 2. connect #### 2.1. Single Pair There is `connect` of String defined in json configuration such as following segment. ```json //

     {
         "connect": "joinField"
     }
 // 

``` > One to One/Many, join json object with JoinField ( Batch Mode ) 1. Pick data from reference data by `sourceField` name. 2. Join data based on `joinField` in Batch mode, connect json object/array. 3. Build new attribute key-pair `name = json object/array`. > JoinField, SourceField, Name. Result: `name = JsonObject / JsonArray`. #### 2.2. Multi Join There is `connect` of JsonObject defined in json configuration such as following segment. ```json //

     {
         "connect": {
             "sourceField1": "joinField1",
             "sourceField2": "joinField2"
         }
     }
 // 

``` > One to One/Many, join json object with JoinFields ( Batch Mode ) 1. Pick data from reference data by `sourceField1` and `sourceField2` name. 2. Join data based on `joinField1` and `joinField2` in Batch mode, connect json object/array. 3. Build new attribute key-pair `name = json object/array`. > JoinFields, SourceFields, Name. Result: `name = JsonObject / JsonArray`. ### 3. K-V 1. Left field is `sourceField` of reference record - `referenceField`. 2. Right field is `joinField` of current record - `currentField`.
