Interface AoRay<T>

All Known Implementing Classes:

AbstractRay, RayBatch, RaySingle

public interface AoRay<T>

Reference Processor ( Ray )

1. Intro

The field of reference calculation components, after all the data have been read, these components could process reference field based on the records.

Here are three categories of attribute’s type:

1. INTERNAL : The standard attribute that has been mapped to database.
2. REFERENCE : The reference attribute that has been mapped to other dependency attributes.
3. EXTERNAL : The reserved attribute that has been mapped to third-part system.

2. Generic T

The T type should be two common object such as:

• JsonObject content of Json Record, the core type is Record.
• JsonArray content of Json Record[], the core type is Record[].

3. Standard Mode

3.1. INTERNAL

This kind of attribute support following features:

• It should be mapped to X_ENTITY fields instead of storing in other place.
• The data type must be based on database column type.
• X_ENTITY column type has been defined in abstract virtual layer to support Type Mapping.

3.2. REFERENCE

This kind of attribute support following features:

1. Complex Type: Such as up and down, the data format is JsonObject/JsonArray, calculated to the result here.
2. Dependency Type: The type is calculated by other INTERNAL field.
