Hello, this is my problem:
I have a map:
typedef map<string, bfdb_recordBFDB ;
where:
typedef struct
{
size_t seq_no;
StdBloomFilter bf;
} bfdb_record;
where:
class StdBloomFilter : public BloomFilter
{
private:
vector<bool__fi lter;
size_t __size;
public:
StdBloomFilter( ):__filter(0),_ _size(0){};
StdBloomFilter( size_t _size): __filter(_size) , __size(_size) {};
StdBloomFilter( const StdBloomFilter& _source);
virtual ~StdBloomFilter (){};
operator CountingBloomFi lter();
StdBloomFilter& operator=(const StdBloomFilter& );
void set(size_t _pos);
bool test(size_t _pos) const;
void clear();
size_t size() const;
void merge(const StdBloomFilter& _source);
string to_string();
};
now I want to insert structure into my map:
__db.insert(mak e_pair(_id,_inf o));
or
__db[_id] = _info;
or
__db.insert(BFD B::value_type(_ id, _info));
I get a runtime error:
8 [main] LE 2560 _cygtls::handle _exceptions: Exception:
STATUS_ACCESS_V IOLATION
985 [main] LE 2560 open_stackdumpf ile: Dumping stack trace to
LE.exe.stackdum p
Is something in StdBloomFilter missing. If I change bf to int type in
the bfdb_record struct then everything works, but that is not what I
need!!!

That's C. You want
struct bfdb_record
{
size_t seq_no;
StdBloomFilter bf;
};
Are you sure you want to copy the entire StdBloomFilter object each time
you do an insert?
where:
class StdBloomFilter : public BloomFilter
{
private:
vector<bool__fi lter;
size_t __size;
Those are illegal names, anything starting with double underscore is
reserved.

What does your StdBloomFilter copy constructor do?

Ian Collins.
StdBloomFilter& StdBloomFilter: :operator=(cons t StdBloomFilter&
_source)
{
this->__size=_source .__size;
this->__filter =_source.__filt er;
}
And what should it do? These are no pointers. These should be copies
by value, right? It was not working, so I added this dummy copy
constructor, but it still does not work. ua****@gmail.co m wrote:

You realy should get rid of these illegal names.

Run you code under a debugger and see what it is doing. You don't show
the base class, so the problem may well be in there.

I can put StdBloomFilter object into a vector<StdBloom Filterand I
tried to get rid of any base class - does not help. Base class is an
abstract interface. ua****@gmail.co m wrote:

You should be able to see the last line in your code.
I assume you have implemented the assignment operator as well?

Well the assignment is smth like:
bool BFDatabase::upd ate(const string& _id, const bfdb_record& _info)
{
BFDB::iterator iter = __db.find(_id);
if (iter==__db.end ())
{
//__db.insert(mak e_pair(_id,_inf o));
__db[_id] = _info;
//__db.insert(BFD B::value_type(_ id, _info));
return true;
}
return false;
}
But the problem is the following:
This works:
StdBloomFilter bf(100);
vector<StdBloom Filtervec;
vec.push_back(b f);
And this does not:
map<int,StdBloo mFilterm;
m.insert(make_p air(5,bf)); ua****@gmail.co m wrote:

This is not the copy ctor. Show us your

The Top Level Design:
The class Base is a factory class with a twist. It uses the Assembly/Type
classes to extract all types that inherit from it and add them to the list
of types that inherit from it. During run time, using a static method, the
class creates an instance of the derived class using the Activator class and
returns it. This design pattern is very similar to the design pattern
applied by the Assembly class.

In C++ an overridden virtual function in a derived class must have the exact
same signature of the function which is overridden in the base class, except
for the return type which may return a pointer or reference to a derived
type of the base class's return type.
In .NET the overridden virtual function is similar, but an actual parameter
of the function can be a derived reference from the base class's reference
also.
