All Implemented Interfaces:

@Participant(value="ConcreteElement")
public class IntegerValuedVisitableSequence
extends AbstractVisitableSequence<Integer>

An integer valued visitable sequence allows any sequence delivering Integer values to become value visitable using the SequenceValueVisitor.visitIntegerValued(Sequence, Object) visitation method and is type visitable for any known sub-interface of Sequence that is implemented by the sequence.

Implementation notes:
Like StringValuedVisitableSequence, this sequence type could have declared a type parameter like <E extends Number> to allow this class to be utilised with any sub-class of Number, e.g. not only Integer, but also Long, Double, BigDecimal, etc. But since type parameters are erased at runtime, this class would have to call a single visitation method like visitNumberValued(Sequence<? extends Number>, ..), and the possibility to distinguish on a specific numeric value type delivered by a sequence is lost (unless of cause one would be so careless as to use the instanceof operator on actual sequence values, which is a really bad idea).

Constructor Detail

IntegerValuedVisitableSequence

public IntegerValuedVisitableSequence(Sequence<Integer> sequence)

Constructor.

Parameters:

sequence - The decorated sequence that will become visitable; cannot be null.

Throws:

NullPointerException - If sequence is null.

Method Detail

accept

public <P> void accept(SequenceValueVisitor<P> visitor,
                       P argument)

Description copied from interface: ValueVisitableSequence

Visits this visitable sequence using the value visitor supplied as visitor.

Type Parameters:

P - The type of visitor-supplied argument. Use Void for visitors that do not need an additional argument.

Parameters:

visitor - The visitor; never null.

argument - A context supplied argument, if any.

copy

public IntegerValuedVisitableSequence copy()

Returns a deep copy of this object. The decorated sequence is not copied.

Returns:

The copy; never null.
