# Traced

final class Traced[TraceData](val extractTrace: Model => TraceData) extends ViewComponent[Model], TraceGeneratingView[Model, TraceData]

A view that wraps around another, collecting a log or trace of events while delegating its actual event-handling to the wrapped view. Provides additional methods for accessing such traces: trace, simulateAndGet, and startAndGet. A few examples of using these methods are given below.

`simulate` 500 clock ticks on the trace-collecing view and print the trace of clock ticks accompanied by descriptions of the view’äs `model`.

    for (traceItem, traceEvent) <- myTracedView.simulateAndGet(500) do
       println(traceEvent + ": " + traceItem)

Or, equivalently:

    myTracedView.simulate(500)
     for (traceItem, traceEvent) <- myTracedView.trace do
       println(traceEvent + ": " + traceItem)

Alternatively, start the trace-collecting view and run it interactively until it is done or a tick limit is reached. Then print the trace of ticks and GUI events accompanied with descriptions of the view’s `model`.

    val futureTrace = myTracedView.startAndGet(tickLimit=100) recover {
       case Aborted(message, partialTrace) => partialTrace
     }
     for trace <- futureTrace; (traceItem, traceEvent) <- trace do
       println(traceEvent + ": " + traceItem)

override def equals(that: Any): Boolean

Compares the receiver object (`this`) with the argument object (`that`) for equivalence.

Compares the receiver object (`this`) with the argument object (`that`) for equivalence.

Any implementation of this method should be an equivalence relation:

- It is reflexive: for any instance `x` of type `Any`, `x.equals(x)` should return `true`.
- It is symmetric: for any instances `x` and `y` of type `Any`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is transitive: for any instances `x`, `y`, and `z` of type `Any` if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override `hashCode` to ensure that objects which are "equal" (`o1.equals(o2)` returns `true`) hash to the same scala.Int. (`o1.hashCode.equals(o2.hashCode)`).

## Parameters

that

  the object to compare against this object for equality.

## Attributes

Returns

  `true` if the receiver object is equivalent to the argument; `false` otherwise.

override def hashCode(): Int

Calculate a hash code value for the object.

Calculate a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (`o1.hashCode.equals(o2.hashCode)`) yet not be equal (`o1.equals(o2)` returns `false`). A degenerate implementation could always return `0`. However, it is required that if two objects are equal (`o1.equals(o2)` returns `true`) that they have identical hash codes (`o1.hashCode.equals(o2.hashCode)`). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the `equals` method.

## Attributes

Returns

  the hash code value for this object.
