Sequencer<SequenceItemType extends SequenceItem> class Null safety

A Component that consumes Sequences and SequenceItems and properly forwards them to an output stream to be driven by a Driver.

If there is no special behavior required, using the default implementation of Sequencer is perfectly functional and just passes items directly through to the output stream.



Sequencer(String name, Component? parent)
Constructs a basic Sequencer of SequenceItemType named name which passes items directly through without additional processing to stream.


hashCode int
The hash code for this object.
read-only, inherited
isConnected bool
Returns true iff there is exactly one listener to stream, which should be a Driver.
logger Logger
A Logger for messages related to the test or testbench.
late, final, inherited
name String
A name for this instance of the Component.
final, inherited
parent Component?
The Component which constructed and contains this Component.
final, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
stream Stream<SequenceItemType>
The output Stream of SequenceItemType from this Sequencer, intended to be consumed by a Driver.


add(SequenceItemType item) → void
Adds a single item to this Sequencer to be passed on to the associated Driver.
build() → void
Performs additional build-related activities required before run.
@mustCallSuper, inherited
check() → void
Performs additional checks at the end of the simulation.
fullName() String
A descriptive name including the full hierarchical path of this Component.
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.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
run(Phase phase) Future<void>
Executes this Component's activities related to running the test.
@mustCallSuper, inherited
start(Sequence<Sequencer<SequenceItem>> sequence) Future<void>
Starts running the Sequence.body on this Sequencer.
toString() String
A string representation of this object.


operator ==(Object other) bool
The equality operator.
