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.

Inheritance

Constructors

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