Alexander Portnov updated ANN-28:
---------------------------------

    Attachment: annotations-any-patch2.txt

Added @MetaData annotation to avoid duplicate @MetaValue mappings on every property of the same type. @MetaData allows to specify mappings only once on the Interface itself. Also added metaDataClass attribute to @Any and @ManyToAny annotations. This is useful when property declaration uses generics. 

For example:

public class PropertyList<T extends Property> {
	private T someProperty;

...

	@Any(idType="integer", metaType="string", 
			columns = {
				@Column(name="property_type"),
				@Column(name="property_id")},
			metaDataClass = Property.class,	
			cascade= CascadeType.ALL)
	public T getSomeProperty() {
		return someProperty;
	}

}

Where Property is mapped as following:

@MetaData({
	@MetaValue(value="S", targetEntity=StringProperty.class),
	@MetaValue(value="I", targetEntity=IntegerProperty.class)
	})
public interface Property {

	public String getName();
	public String asString();
}
