PerceptionCollectable (Open Traffic Sim road classes 1.04.04 API)

Type Parameters:

H - headway type

U - underlying object type

All Superinterfaces:

Iterable<H>, PerceptionIterable<H>

All Known Implementing Classes:

AbstractPerceptionIterable, AbstractPerceptionReiterable, DownstreamNeighborsIterable, LaneBasedObjectIterable, MultiLanePerceptionIterable, SortedSetPerceptionIterable, UpstreamNeighborsIterable
```
public interface PerceptionCollectable<H extends Headway,U>
extends PerceptionIterable<H>
```
Iterable that additionally provides support for PerceptionCollectors. These gather raw data, to only 'perceive' the result.

- Method Detail
  - collect
```
default <C,I> C collect(PerceptionCollectable.PerceptionCollector<C,? super U,I> collector)
```
    Collect the underlying objects in to a perceived result. This methodology is loosely based on Stream.collect().
    
    Type Parameters:
    
    C - collection result type
    
    I - intermediate type
    
    Parameters:
    
    collector - PerceptionCollector<C, ? super U, I>; collector
    
    Returns:
    
    C; collection result
  - collect
```
<C,I> C collect(Supplier<I> identity,
                      PerceptionCollectable.PerceptionAccumulator<? super U,I> accumulator,
                      PerceptionCollectable.PerceptionFinalizer<C,I> finalizer)
```
    Collect the underlying objects in to a perceived result. This methodology is loosely based on Stream.collect().
    
    Type Parameters:
    
    C - collection result type
    
    I - intermediate type
    
    Parameters:
    
    identity - Supplier<I>; the initial intermediate result value
    
    accumulator - PerceptionAccumulator<? super U, I>; accumulator
    
    finalizer - PerceptionFinalizer<C, I>; finalizer
    
    Returns:
    
    C; collection result
  - underlying
```
Iterator<U> underlying()
```
    Returns an iterator over the underlying objects.
    
    Returns:
    
    Iterator<U>; iterator
  - underlyingWithDistance
```
Iterator<PerceptionCollectable.UnderlyingDistance<U>> underlyingWithDistance()
```
    Returns an iterator over the underlying objects coupled with the distance.
    
    Returns:
    
    Iterator<UnderlyingDistance<U>>; iterator
