示例1: if
Acad::ErrorStatus
ArxDbgUtils::verifyEntityReference(const AcDbEntity* ent, const AcDbObjectId& idToValidate,
AcRxClass* classType, bool allowNull, bool allowErased)
{
if (ent == NULL) {
ASSERT(0);
return Acad::eInvalidInput;
}
// first check for NULL
if (idToValidate == AcDbObjectId::kNull) {

else

}
// now open it up and see what it is
Acad::ErrorStatus es;
AcDbEntity* entToValidate;
es = acdbOpenAcDbEntity(entToValidate, idToValidate, AcDb::kForRead);

// which should always be the case!

entToValidate->close();

}
// make sure that references are from the same block
// This can fail from a simple deepClone() to make a
// blockTableRecord. If the user didn't pick all the
// referenced objects in the anchor at the time of
// making the block, they will still point to the
// entities in modelSpace... which will eventually crash
// the whole thing.

entToValidate->close();

}
// see if they want to validate based on object type
