private static class ExtractorFactory.ElementMapExtractor
extends Object
implements Extractor<ElementMap>
The
ElementListExtractor
object is used extract the
constituent parts of the provided union annotation. This can
also be used to create a Label object for each
of the declared annotation for dynamic serialization.-

ElementMapExtractor
Constructor for theElementMapExtractor
object. This is used to create an extractor that can be used to extract the various labels used to serialize and deserialize objects.- Parameters:
contact
- this is the contact annotated as a unionunion
- this is the union annotation to extract fromformat
- this is the format used to style elements- Throws:
Exception

Method Details

getAnnotations
This is used to acquire each annotation that forms part of the union group. Extracting the annotations in this way allows the extractor to build aLabel
which can be used to represent the annotation. Each label can then provide a converter implementation to serialize objects.- Specified by:
getAnnotations
in interfaceExtractor<ElementMap>
- Returns:
- this returns each annotation within the union group
-
getLabel
This creates aLabel
object used to represent the annotation provided. Creating the label in this way ensures that each union has access to the serialization methods defined for each type an XML element name.- Specified by:
getLabel
in interfaceExtractor<ElementMap>
- Parameters:
element
- this is the annotation to create the label for- Returns:
- this is the label created for the annotation
-
getType
Each annotation can provide a class which is used to determine which label is used to serialize an object. This ensures that the correct label is selected whenever serialization occurs.- Specified by:
getType
in interfaceExtractor<ElementMap>
- Parameters:
element
- this is the annotation to extract the type for- Returns:
- this returns the class associated with the annotation
