PendingDriver<SequenceItemType extends SequenceItem> class abstract

A special type of Driver which automatically pulls items out of the sequencer and into a queue of pendingSeqItems.

It also handles raising objections while there are pending items and ensuring that the queue is empty at the end of the test.

PendingDriver(String name, Component? parent, {required Sequencer<SequenceItemType> sequencer, Future<void> timeout()?, Future<void> dropDelay()?, bool enableEndOfTestEmptyCheck = true}): Creates a new PendingDriver attached to sequencer.

components → UnmodifiableListView<Component>: A List of all children Components.
no setterinherited
dropDelay → (Future<void> Function()?): A function called each time an objection would drop due to an empty pendingSeqItems, but the objection will only be dropped if there is no further activity before it completes.
final
enableEndOfTestEmptyCheck → bool: If true, will check at the end of the test that there are no pending items remaining to be driven.
final
hashCode → int: The hash code for this object.
no setterinherited
logger → Logger: A Logger for messages related to the test or testbench.
latefinalinherited
name → String: A name for this instance of the Component.
finalinherited
parent → Component?: The Component which constructed and contains this Component.
finalinherited
pendingSeqItems ↔ Queue<SequenceItemType>: A Queue of items that have been received from the sequencer and are waiting to be driven. After an item has been driven, it should be removed.
latefinal
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sequencer → Sequencer<SequenceItemType>: The sequencer from which this Driver acquires new items to drive.
finalinherited
timeout → (Future<void> Function()?): A function called each time there is something added or removed from the pendingSeqItems, and if it completes before an objection is dropped or some further activity occurs, an error is flagged.
final

build() → void: Performs additional build-related activities required before run.
inherited
check() → void: Performs additional checks at the end of the simulation.
override
fullName() → String: A descriptive name including the full hierarchical path of this Component.
inherited
hierarchy() → List<Component>: Returns a List of Components representing the full hierarchy of this Component, with the top-most parent at index 0 and this as the last element of the List.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
run(Phase phase) → Future<void>: Executes this Component's activities related to running the test.
override
toString() → String: A string representation of this object.
