oddbray and explodegeometry
oddbray and explodegeometry
i noticed that when calling explodegeometry with an oddbray that the return code was eok and i got back an oddbray in the entity list.
this turned out to cause a stack overflow problem in a recursive function i wrote. it attempts to simplify the things it doesn't know about in order to handle items such as mtext or rtext or mline (for instance).
i have placed a test in my recursive function which makes sure the entity is a database resident object before trying to explode it but i am uncertain if there any entities which might explode, then explode again (say a dimension with mtext). if so i don't wish the test to reject these from explosion.
i suppose the test i need answers the question, "is entity a the same type as entity b?" note that having the same base type does not count, so i cannot use iskindof.
i am using version 2.3.0 with the drawing exported by odwriteex (acad2007, dwg format).
thanks.

perhaps obj1->isa()==obj2->isa(), is the test you are looking for.

that did it
thanks vladimir that seemed to do the trick.
here is how the code looks. the variable ent is an oddbentityptr that is set. the call traverseentity is a recursive call which tests for certain entity types and otherwise hits this explode code.
code:
odrxobjectptrarray::size_type i;
odrxobjectptrarray entities;
odresult res;
res = ent->explodegeometry(entities);
if ( res == eok )
{
for (i = 0; i < entities.length(); i++)
{
if ( ent->isa() != entities[i]->isa() )
traverseentity(entities[i], false);
else
{
str.format("%s (%s) is not a supported entity and cannot be reduced", (const char *)ent->isa()->name(), (const char *)ent->handle().ascii());
dxfin_warning(str);
}
}
}
