QDLMetaModule (QDL root module 1.6.0 API)

All Superinterfaces:

Serializable

All Known Implementing Classes:

Crypto, DynamoDB, HTTPClient, QDLCLITools, QDLConvert, QDLDB, QDLMail, StatefulExample
```
public interface QDLMetaModule
extends Serializable
```
One way to make a Java module is to have a super class and have each method or variable defined as non-static inner classes. These then can share state between them. This interface should be implemented for those classes in order to ensure compatibility with the system. It has no methods and is a marker interface.
A typical basic
Let us say you wrote a module that has read a configuration file and named configuration. Stash those in a JSON object, along with any other state you need to reconstruct, which will be returned in serializeToJSON() and when the module is deserialized, these values can be reset from deserializeFromJSON(JSONObject). Then you can have a flag that checks if the configuration is active and if not, re-read the configuration. This allows you to seamlessly have your classes be saved by the system.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`deserializeFromJSON(net.sf.json.JSONObject json)`
`net.sf.json.JSONObject`	`serializeToJSON()`	Send back a serialization of internal state for this object.

- Method Detail
  - serializeToJSON
```
net.sf.json.JSONObject serializeToJSON()
```
    Send back a serialization of internal state for this object. This allows for the state you choose to be serialized and then reloaded.
    NOTE
    There is no canonical form for this. Set it how you will and deserialize it accordingly.
    
    Returns:
  - deserializeFromJSON
```
void deserializeFromJSON(net.sf.json.JSONObject json)
```
