Class DelegatingCompositeFieldTransformer

java.lang.Object

info.magnolia.ui.form.field.transformer.basic.BasicTransformer<com.vaadin.data.util.PropertysetItem>

info.magnolia.ui.form.field.transformer.composite.DelegatingCompositeFieldTransformer

All Implemented Interfaces:

I18NAwareHandler, Transformer<com.vaadin.data.util.PropertysetItem>

public class DelegatingCompositeFieldTransformer
extends BasicTransformer<com.vaadin.data.util.PropertysetItem>

This delegating Transformer is dedicated to the CompositeField and SwitchableField; it simply delegates property handling to the configured sub-fields.

Therefore, sub-fields use their own transformers to store the field value; e.g. with BasicTransformer properties are named after their respective FieldDefinition.getName().

Method Detail

writeToItem

public void writeToItem(com.vaadin.data.util.PropertysetItem newValue)

This transformer's write implementation is empty. We do not need to write to the item as this is delegated to the sub-fields.

Specified by:

writeToItem in interface Transformer<com.vaadin.data.util.PropertysetItem>

Overrides:

writeToItem in class BasicTransformer<com.vaadin.data.util.PropertysetItem>

readFromItem

public com.vaadin.data.util.PropertysetItem readFromItem()

Returns a representation of the child items as a PropertysetItem; this is merely a map whose keys are the configured names of the sub-fields, and whose values are the child items, wrapped as ObjectProperties.

Specified by:

readFromItem in interface Transformer<com.vaadin.data.util.PropertysetItem>

Overrides:

readFromItem in class BasicTransformer<com.vaadin.data.util.PropertysetItem>
