Class CellBackup

java.lang.Object
  com.sun.electric.database.CellBackup

public class CellBackup
extends java.lang.Object

CellBackup is a pair of CellRevision and TechPool. It caches data that can be calculated when Technology is already known, but subcells are unknown.

                       ImmutableArcInst[] arcsArray,
                       ImmutableExport[] exportsArray,
                       TechPool superPool)

Creates a new instance of CellBackup which differs from this CellBackup. Four array parameters are supplied. Each parameter may be null if its contents is the same as in this Snapshot.

Parameters:

nodesArray - new array of nodes

arcsArray - new array of arcs

exportsArray - new array of exports

superPool - TechPool which defines all used technologies

Returns:

new snapshot which differs froms this Snapshot or this Snapshot.

Throws:

java.lang.IllegalArgumentException - on invariant violation.

ArrayOutOfBoundsException - on some invariant violations.

withRevisionDate
