Interface ReferenceExpression<I extends uk.ac.ed.epcc.webapp.Indexed>

Type Parameters:

I - type of reference

All Superinterfaces:

PropExpression<uk.ac.ed.epcc.webapp.model.data.reference.IndexedReference<I>>, uk.ac.ed.epcc.webapp.Targetted<uk.ac.ed.epcc.webapp.model.data.reference.IndexedReference<I>>

All Known Implementing Classes:

DoubleDeRefExpression, IndexedTag, ReferenceTag

public interface ReferenceExpression<I extends uk.ac.ed.epcc.webapp.Indexed>
extends PropExpression<uk.ac.ed.epcc.webapp.model.data.reference.IndexedReference<I>>

A prop-expression for references In this case the getTarget method is insufficient to define the type of the result fully so we add additional methods to provide the missing information.

ReferenceExpression<I> copy()

Description copied from interface: PropExpression

Generate an equivalent (and where possible immutable) copy of this expression. Most implementing types should themselves be immutable, calling copy on their arguments and returning a self-reference for copy. In this case the return type of the function should be narrowed to the implemeting sub-type.

Specified by:

copy in interface PropExpression<uk.ac.ed.epcc.webapp.model.data.reference.IndexedReference<I extends uk.ac.ed.epcc.webapp.Indexed>>

Returns:

PropExpression
