public TargetRememberLastLabel(java.lang.String backgroundLabel,
boolean offset)
- offset determines how the memory and base sequences will be
aligned. If true, they'll be aligned like this:
MEM O O S S S E L
BASE O S S O E L O
otherwise, they'll be aligned like this:
MEM O S S S E E L
BASE O S S O E L O

public Instance pipe(Instance carrier)
- Description copied from class:
Pipe

This is the method by which all pipes are eventually run.
One can create a new concrete subclass of Pipe simply by
implementing this method.
