Syntax:
|
(bool:select2 in-body in-cells [acis-opts])
|
|
|
Arg Types:
|
in-body
|
entity
|
|
in-cells
|
graph | (entity ...)
|
|
acis-opts
|
acis-options
|
|
|
Returns:
|
entity
|
|
|
Description:
|
This extension modifies the
in-body body based on either the results of graph theory or a
Cellular Topology cell list in
in-cells. When
in-cells contains cell entities, these are the only entities that should be kept. When
in-cells is a graph, the graph could be the result of extensive graph theory operations. However, the resulting graph still maps to cells in the body and represents the cells to keep.
|
|
|
The mapping of cells in a graph to entities will not be the same from execution to execution.
|
|
|
in-body is an input entity.
|
|
|
in-cells is an input entity that contains either cell entities or a graph.
|
|
|
The optional
acis-opts contains parameters for versioning and journaling.
