Interface FieldElement

All Known Implementing Classes:
AbstractTextFieldElement, AnnotatedTextFieldElement, ClangFieldElement, CompositeFieldElement, StrutFieldElement, TextFieldElement
public interface FieldElement
Used by Fields to combine text, attributes and location information (for example to and from screen and data locations). FieldFactory classes can use the various implementations of this interface, or create new ones, to include additional information specific to the fields that they create.
