Class RResult

java.lang.Object

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.

// <pre><code class="json">
    {
        "connect": "joinField"
    }
// </code></pre>

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.

// <pre><code class="json">
    {
        "connect": {
            "sourceField1": "joinField1",
            "sourceField2": "joinField2"
        }
    }
// </code></pre>

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.
