Direct Known Subclasses:

RayBatch, RaySingle

extends Object
implements AoRay<T>

Abstract Reference Processor

1. Intro

Template pattern to provide all the calculation metadata in current class, all sub-classes could share the data structure that current class defined.

2. Components

Here are two hash maps that stored field = xx, the xx means components of following two categories:

• RaySource: The field calculator component that contains code logical ( Action ).
• DataQRule: The field definition rules POJO data object that contains metadata definition ( Rule ).

Method Detail

on

public AoRay<T> on(DataTpl tpl)

Bind the component to data model template DataTpl.

The critical code logical is as following:

• Bind the DataTpl to instance member tpl.
• Be sure the DataAtom in DataTpl is valid.
• Calculate the two hash maps in this method.

Specified by:

on in interface AoRay<T>

Parameters:

tpl - DataTpl The template that will be bind.

Returns:

AoRay The component reference

Throws:

_501AnonymousAtomException - Atom in tpl contains errors.

attach

public T attach(T input)

This method will modify the input Record element(s).

Here contains shorten code logical when the hash map is EMPTY, skip reference calculator.

Specified by:

attach in interface AoRay<T>

Parameters:

input - Input element of Record for single/multi

Returns:

Return the modified data record(s).

doAttach

public abstract T doAttach(T input)

This method must be inherit by all sub-classes, it provide reference data mounting.

Parameters:

input - Input element of Record for single/multi

Returns:

Return the modified data record(s).
