@StableMinor(version="14.0",
             sinceVersion="4.0")
public abstract class AbstractSourceData
extends Object
implements ISourceData

Abstract implementation of a ISourceData that implements the default convertion behaviour. This convertion behaviour assumes the key is equals to the field id in the source.

This implementation does no conversion during the put method, it does conversion only during the get method. But it offers the convertValue(String, Class, Object) method to be used by it subclasses in the put implementation.

Since:

4.0.4
