public interface MiTopology

List of cells interface.

A generic interface for a mesh topology.

Method Summary

Modifier and Type	Method and Description
long	getTimeStamp() Returns for this topology a unique time stamp across all topologies in the application.
boolean	hasDeadCells() Returns true if the topology contains dead cells.

Method Detail

getTimeStamp

long getTimeStamp()

Returns for this topology a unique time stamp across all topologies in the application.

When the content of the topology changes, the time stamp must increase. The time stamp allows extractors to identify this topology and to be aware of any changes to it.

Note: MxTimeStamp can be used to generate a valid time stamp.

Returns:

a time stamp value on this topology

hasDeadCells

boolean hasDeadCells()

Returns true if the topology contains dead cells.

When false, the cells traversal can be optimized by not testing the isDead method of each individual cells.

Returns:

true if the topology contains dead cells
