| Returns the list of selected entities. Works by calling the method Explore on each input entity : it can be rejected, taken for output, or to explore.

Detailed Description
A SelectExplore determines from an input list of Entities, a list obtained by a way of exploration. This implies the possibility of recursive exploration : the output list is itself reused as input, etc... Examples : Shared Entities, can be considered at one level (immediate shared) or more, or max level.
Then, for each input entity, if it is not rejected, it can be either taken itself, or explored : it then produces a list. According to a level, either the produced lists or taken entities give the result (level one), or lists are themselves considered and for each item, is it taken or explored.
Remark that rejection is just a safety : normally, an input entity is, either taken itself, or explored A maximum level can be specified. Else, the process continues until all entities have been either taken or rejected

Analyses and, if required, Explores an entity, as follows : The explored list starts as empty, it has to be filled by this method. If it returns False, <ent> is rejected for result (this is to be used only as safety) If it returns True and <explored> remains empty, <ent> is taken itself for result, not explored If it returns True and <explored> is not empty, the content of this list is considered : If maximum level is attained, it is taken for result Else (or no max), each of its entity will be itself explored.

overridevirtual |
Returns a text saying "(Recursive)" or "(Level nn)" plus specific criterium returned by ExploreLabel (see below)
Implements IFSelect_Selection.
◆ Level()
| Standard_Integer IFSelect_SelectExplore::Level | ( | ) | const |
Returns the required exploring level.
◆ RootResult()
|
overridevirtual |
Returns the list of selected entities. Works by calling the method Explore on each input entity : it can be rejected, taken for output, or to explore. If the maximum level has not yet been attained, or if no max level is specified, entities to be explored are themselves used as if they were input.
Implements IFSelect_Selection.
Reimplemented in STEPSelections_SelectInstances.
