Implement a class extending the class com.noheto.restapi.APIBusinessServiceAdapter to modify some properties of an instance object, before saving it after a creation or modification.

It is necessary to indicate in the action configuration (so in the JSON description) which component you want to use (indicating the plugin and the name of the class).

Methods

beforeCreate: executed before saving after creating a new instance
beforeUpdate: executed before saving after updating an instance
beforeCreateItem: executed before saving a new collection item
updateOrCreate: allow to intercept a creation or modification if you need to replace the instance, or cancel the process
First argument (com.noheto.restapi.BusinessServiceContext) provides methods:
- getSurfer() to get the surfer
- getAction() to get the action name
- getLogger() to get a RESTAPI plug-in logger
- getLocale() to get the current invokation locale (not the surfer locale)
- isUpdate() to test if the current action does a modification
- isCreate() to test if the current action does a creation
- setInfo(String) to provides an info in response of invocation (string or json string)
- getInfo() to get the current info
- getUpdateProperties() to get the names of updatable properties
- getConfiguration() to get the current action configuration

Example

Copy the concatenation of properties code1 and code2 to property name.

package fr.wedia.demo;

import com.noheto.restapi.APIBusinessServiceAdapter;

import wsnoheto.engine.IObjectWritable;

public class DemoBusinessService extends APIBusinessServiceAdapter {

	@Override
	public void beforeCreate(String action, IObjectWritable newObject) {
	    switch(newObject.getObjectType().toString()) {
	    case "product":
	        // build the name by concatenating the both codes
    		try {
    		    String name = newObject.getProperty("code1") + newObject.getProperty("code2");
    			newObject.setProperty(8, name);
    		} catch (Throwable e) {
    			throw new RuntimeException("Couldn't set product name",e);
    		}
	        break;
	    default:
	        // does nothing
	    }
	}

}

DAM services

It is possible to specify the trigger in the service configuration, but to have a service configuration without JSON, you can use the extension com.noheto.restapi.DamContributionAdapter
