Traced
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 by 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)
Type parameters

-

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
xof typeAny,x.equals(x)should returntrue. - It is symmetric: for any instances
xandyof typeAny,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any instances
x,y, andzof typeAnyifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue.
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.

Calculates a hash code value for the object.
Calculates 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.

Determines if the given state is a “done state” for the view. By default, this is never the case, but that behavior can be overridden.
Once done, the view stops reacting to events and updating its graphics and may close its GUI window, depending on the constructor parameters of the view.

A number of simulated clock ticks are immediately sent to the view; this continues until either the view determines it is done or a predetermined maximum number of ticks has been reached.
