Interface Data<T>

Type Parameters:

T -

All Known Implementing Classes:

JAXBData

public interface Data<T>

Data

Data facilitates lazy marshaling of data with a pre-determined marshaling mechanism.

It stores either Object (defined by Generic <T>) or String.

On asking for Object of type <T>, it will respond with the object if it exists, or unmarshal the string and pass the result back.

On asking for String, it will respond with the String if it exists, or marshal the String and pass the result back.

the "options" available on several functions control the output of this particular call. When blank, they will default to the DataFactory defaults. When present, they override this particular call. The available options are "pretty" (for XML and JSON) and "fragment" (XML only concept), which drops the "" header so you can create larger XML documents from the output.
