Class PassedNcc

java.lang.Object
  com.sun.electric.tool.ncc.PassedNcc

public class PassedNcc
extends java.lang.Object

Cell pairs that have already passed NCC. PassedNcc is used to implement NCC's incremental mode: check only cells that have changed since the last NCC.

Constructor Summary

PassedNcc()

Method Summary

boolean	getPassed(Cell c1, Cell c2) Did Cells c1 and c2 match the last time NCC was run?
void	removeCellsChangedSinceLastNccRun(CellContext[] cellContexts) Purge all Cells that the user changed since the last NCC run.
void	setPassed(Cell c1, Cell c2) Remember that Cells c1 and c2 have passed NCC and are therefore topologically identical

public PassedNcc()

Method Detail

setPassed

public void setPassed(Cell c1,
                      Cell c2)

Remember that Cells c1 and c2 have passed NCC and are therefore topologically identical

getPassed

public boolean getPassed(Cell c1,
                         Cell c2)

Did Cells c1 and c2 match the last time NCC was run?

Parameters:

c1 - Cell one

c2 - Cell two

Returns:

true if Cells c1 and c2 matched the last time NCC was run. Therefore it is safe to assume that c1 and c2 are topologically identical.

removeCellsChangedSinceLastNccRun

public void removeCellsChangedSinceLastNccRun(CellContext[] cellContexts)

Purge all Cells that the user changed since the last NCC run. Then record the time of this new NCC Run.
