copy

public DoubleDeRefExpression<R,T> 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<T extends uk.ac.ed.epcc.webapp.Indexed>>

Specified by:

copy in interface ReferenceExpression<T extends uk.ac.ed.epcc.webapp.Indexed>

Overrides:

copy in class DeRefExpression<R extends uk.ac.ed.epcc.webapp.model.data.DataObject & ExpressionTarget,uk.ac.ed.epcc.webapp.model.data.reference.IndexedReference<T extends uk.ac.ed.epcc.webapp.Indexed>>

Returns:

PropExpression
