4.2 Program Own Initializers

Initializers fill the fields of a newly created document with default values.

Interface to implement

For own initializers you need to implement the interface hox.corem.editor.initialization.Initializer with the method getInitialValue.

Parameters to use

The getInitialValue method gets the following parameters:

Parameter	Type	Description
document	DocumentModel	The document which contains the property to initialize.
`propertyType`	`PropertyTypeModel`	The property to initialize.

Table 4.1. Parameters of the getInitialValue method

Return Type

Depending on the property type for which the initializer is intended to use the method may return the following values (return type is Object):

Property	Default PropertyModel	Value
String	`StringModel`	String
Integer	`IntegerModel`	Integer
Date	`CalendarModel`	Calendar
LinkList	`LinkListModel`	`ResourceHolder[]`
SgmlText	`SgmlTextModel`	`org.w3c.Document`
Blob	`BlobModel`	byte[]

Table 4.2. Return values of the getInitialValue method

Integrate your Initializer into the Site Manager using editor.xml

You can integrate your Initializer into the Site Manager using the element Initializer of the editor.xml file as shown in example.

<DocumentTypes>
	<DocumentType name="SomeType">
		<PropertyType name="SomeProperty">
			<Initializer 
			class="com.customer.example.editor.SimpleInitializer"/>
		</PropertyType>
	</DocumentType>
</DocumentTypes>

Example 4.1. Integrate Initializer in editor.xml

Example:

The next example shows a simple Initializer which checks whether the property to initialize is of type String or not. If it is, the property will get the name of the creator of the document as the initial setting.

import hox.corem.editor.initialization.Initializer;
import hox.corem.editor.proxy.*;
public class SimpleInitializer implements Initializer {
	public Object getInitialValue(DocumentModel doc, 
		PropertyTypeModel p) {
		String result = "";
		try {
			int ver = doc.getLatestVersion();
			PropertyModel pm = doc.getPropertyModel(ver, p.getName());
			if (pm instanceof StringModel) {
				result = doc.getCreator().getName();
			} 
		} catch (Exception e) { } 
		return result;
	}   
}
