IFSelect_SelectExplore Class Reference

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

Public Member Functions

Standard_Integer Level () const
 Returns the required exploring level

Interface_EntityIterator RootResult (const Interface_Graph &G) const
 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

virtual Standard_Boolean Explore (const Standard_Integer level, const Handle< Standard_Transient > &ent, const Interface_Graph &G, Interface_EntityIterator &explored) const =0
 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

TCollection_AsciiString Label () const
 Returns a text saying "(Recursive)" or "(Level nn)" plus
specific criterium returned by ExploreLabel (see below)

virtual TCollection_AsciiString ExploreLabel () const =0
 Returns a text defining the way of exploration

 IFSelect_SelectExplore (const Standard_Integer level)
 Initializes a SelectExplore : the level must be specified on
starting. 0 means all levels, 1 means level one only, etc...
