length_error Class

 

The latest version of this topic can be found at length_error Class.

The class serves as the base class for all exceptions thrown to report an attempt to generate an object too long to be specified.

Syntax

class length_error : public logic_error {  
public:  
    explicit length_error(const string& message);

    explicit length_error(const char *message);

};  

Remarks

The value returned by what is a copy of message.data.

Example

// length_error.cpp  
// compile with: /EHsc /GR /MDd  
#include <vector>  
#include <iostream>  
  
using namespace std;  
  
template<class  T>  
class stingyallocator : public allocator< T>  
{  
public:  
   template <class U>  
      struct rebind { typedef stingyallocator<U> other; };  
   _SIZT max_size( ) const  
   {  
         return 10;  
   };  
  
};  
  
int main( )  
{  
   try  
   {  
      vector<int, stingyallocator< int > > myv;  
      for ( int i = 0; i < 11; i++ ) myv.push_back( i );  
   }  
   catch ( exception &e )  
   {  
      cerr << "Caught " << e.what( ) << endl;  
      cerr << "Type " << typeid( e ).name( ) << endl;  
   };  
}  
\* Output:   
Caught vector<T> too long  
Type class std::length_error
